Yesterday Om put up a GigaOm post, Skype on iPhone to be released as early as next week. While it’s still an unconfirmed “exclusive” rumor (and you can safely bet the eBay PR hounds are looking for any leak source if this is a leak), it does raise the issue of what we should expect the Skype experience to be if Skype for iPhone is released (even as a beta). It also raises the question of what is happening with the overall Skype on Mobile strategy outlined earlier this year by Skype COO Scott Durchslag in a blog post.

What I can confirm is that at the CES press conference back in January, Skype COO Scott Durchslag did say in an interview that Skype was looking to have Skype for iPhone at some future unannounced date. And I did meet the Skype for iPhone product manager at Skype’s CES 2009 reception; he was relieved that he could now at least give out his title, if not details. At the same CES press conference, Skype demonstrated calls made using its Java-based Skype Lite which has been in various forms of beta since last spring.

We’ve seen several attempts at accessing Skype on an iPhone(Truphone, Nimbuzz, Fring). I have also been using iSkoot on the BlackBerry (and at times Nokia N-series) smartphones as well as IM+ for Skype on various devices. Recently I have been able to check out the Skype IM feature of Skype Lite. Using and trialing these services have provided lots of details about feature set requirements for a fully-featured Skype user experience. As a result I have established some criteria for an acceptable “Skype on Mobile” experience.

1. Skype Contacts: bring up a user’s complete list of Skype contacts (regardless of number of contacts); be able to find a contact by typing in the first few letters of a name, see the appropriate real time presence information; launch a Skype chat session or Skype voice call.
2. User interface: I want to look at my Skype contacts, with presence information, and be able to hit the “green” call button on the device to initiate a call to a Skype contact. Hit the red “end call” button to terminate a call. (iSkoot on BlackBerry does this.)
3. Chat messages: I want the device to be able to monitor my Skype IM activity in background, notify me of activity and bring it up at my convenience. (iSkoot on BlackBerry does this.) I also want Skype Public Chat threads maintained as a single session; Nimbuzz treats each participant in a Public Chat as separate “contact” sessions.
4. Receiving calls; I want to be able to receive Skype calls whether I am in the “Skype-enabled” application or using another smartphone application. Receiving calls on the BlackBerry or Nokia smartphone is an option with iSkoot; with any iPhone application you must be in the application to receive a Skype call.
5. Native address book integration: I want to be able to find a contact in the device’s native address book and be able to make a SkypeOut call to a selected Home/Business/Mobile/Other phone number. Truphone has always been diligent about including native address book access; iSkoot also provides this in its more recent releases.
6. Mood message update: while not critical, it is definitely desirable to be consistent with a fully featured Skype service.
7. Battery life management: I want to have minimal battery use; iSkoot demonstrates that handling all the chat and call signaling activity can drain a battery quite quickly, especially if on a WiFi connection. Using BlackBerry’s “push” API’s is one means of addressing this issue. Battery lifetime will be even more important on any potential iPhone application; battery management, including lifetime, has been one of iPhone’s weaker points.
8. Call quality. While certainly limited by the mobile networks’ and smartphones’ inherent audio bandwidth, issues such as echo cancellation and call break-up have arisen with some services. Once again this has not been an issue on iSkoot for BlackBerry calls; however, I have found these issues to occur on calls to Skype contacts via Fring and Truphone on the iPhone.
9. Network quality: I have yet to have a good 3G network experience with AT&T; I have mentioned this in the past during recent trips to California and Nevada. Om has written about it to the point where he switched to using a 8900 Curve on T-Mobile after giving up on Bold and iPhone on AT&T. My vacation location this week only has AT&T 2G service available and, even then, it is minimal reliability. (T-Mobile 2G definitely has “more bars” here.) My only recommendation here can be, if you wish great 3G reliability and reception on a BlackBerry Bold or iPhone, move to Canada and use Rogers where 3G network availability and quality has never been an issue for me.

Here is my current Skype access on mobile situation:

• iSkoot provides excellent call quality as well as chat sessions in background (including content from sessions over the previous day or two). iSkoot’s major technical downside relates to battery drain, an issue that is correctable via newer “push” API’s. Costs will vary by my smartphone location:
  • Within the Toronto local calling area: no charge for voice or data.
  • Within Canada: long distance charges (~$0.25/minute) for voice; no charge for data. It’s still cost effective to use iSkoot.
  • Outside Canada: roaming charges ($0.95/minute in U.S.; much more in Europe) plus long distance charges make iSkoot a very expensive service. Only Skype services on 3 have partially addressed this issue in all the countries served by 3.
• Truphone’s Skype access:
  • Voice: Truphone for iPhone provides unacceptable Skype call quality (serious echo cancellation issues) but can complete calls to Skype contacts over a WiFi access point. The Truphone client must be open to receive Skype voice calls. Truphone Anywhere, which requires access to the carrier’s network for voice, has the same cost considerations as listed for iSkoot above. (To give due credit, a Truphone call over WiFi this afternoon directly to one of my iPhone contacts did not have echo issues.)
  • Chat: The Truphone client can only support IM chat sessions when the Truphone client is open. The content seen comprises only those messages exchanged while in the “current” chat session; all chat sessions are closed when you leave the Truphone application; previous content is not recallable.
• Skype for Mobile (aka Skype Lite) on Nokia E71:
  • As making Skype voice calls is reliant on having carrier relationships, I can only access Skype chat activity via WiFi; in this case previous Skype chat sessions can be recalled. Skype has announced they are working with carriers in ten named countries but no other details have been provided.

While I would expect any Skype on iPhone offering would use the “Skype Lite”/iSkoot /Truphone Anywhere architecture involving use of the data channel for chat and call signaling but the inherent carrier voice channel for voice, recall that Skype Lite is basically a Java application that has been in beta for some time whereas iPhone on Skype would require a relatively new and yet-to-be-beta-tested Apple OS/X application. On the other hand, iPhone 3.0 will address some of these issues.

Bottom line – there are many issues to be addressed to have Skype on the iPhone  maintain Skype’s reputation for providing an easy-to-use, reliable, scalable consumer service. While I won’t totally discount the rumors of Skype on iPhone, my prediction for what Skype may announce next week at CTIA Wireless: carrier agreements related to using Skype Lite:

• First announced last April (as Skype for Mobile), Skype Lite is at the point where Skype needs to announce some carrier agreements to demonstrate that Skype Lite actually has carrier adoption.
• Carrier adoption is critical to the business model for generating revenue from Skype Lite.
• It would be consistent with the Skype for Mobile strategy about which Scott Durchslag blogged during the Mobile World Conference in February.
• This is a major international conference where wireless carriers and vendors do business.

We’ll be looking forward to seeing what announcements do come out next week.

Yesterday’s announcement of the Skype for SIP beta created lots of commentary in the blogosphere; it remained the leading topic on Techmeme for several hours.

• Phil Wolff over at Skype Journal, in “Skype For SIP: Big Money, Skypeless, Brand Destroyer”, outlines some of the positioning with respect to Skype for Asterisk, channel schism issues and worries that it abandons Skype’s central tenants and could undermine the brand.
• Alec Saunders, in “Skype embraces SIP; announces beta service for business users”, talks about the impact on businesses using legacy PBX’s, the increased pressure on international long distance markets and a reminder that about 1/3 of all current Skype traffic is business related.
• Jason Goecke at Ahearsion, a Skype for Asterisk beta developer, worries about the impact on the market for Skype for Asterisk in “Skype for SIP = Skype for Asterisk DOA?”

But most interesting was the Voice On The Web Public Chat session that ensued. Being on a vacation I was away from my laptop for about seven hours (yes, it was a great day to be golfing) but when I returned I found a session that not only provided the flavor of the vibrant debate going on but also many answers. The key – Chris Moore, Skype’s Senior Product Manager responsible for Skype for SIP joined into the discussion to make several points:

• Most importantly – this is Skype for SIP beta; his team is looking for feedback from a range of beta testers, not only third party developers but also the IP PBX vendors themselves. To quote Chris:
  

  Yep, whole idea is to get feedback, see what people want/don’t want to help prioritize development of new features. Our group, Skype For Business, is getting a lot of focus and its a key strategic focal point for Skype now. We’ll never get it completely right at the start, but a start is still a start

• To qualify as a beta tester you need to have some experience with configuring IP PBX’s that are currently in the market. For instance, “you must have, and be able to configure, your own SIP Enabled PBX that supports G.729 codec.”
• Beta testers will need to create a temporary Skype name to use in the beta program; the issue of a separate SkypeID and how it was handled was hotly debated.
  One point to clarify:

  Skype for SIP actually can allow multiple Skype IDs to be mapped through to a single SIP identity. However, during the beta period, we are only supporting a 1 to 1 mapping due to the fact that Skype’s advanced Business Control Panel (BCP) configuration portal is not yet available at this time. If a company wishes to configure multiple Skype ID’s mapped to a SIP identity, we can accommodate this for a subset of the beta trial participants.

• The key connections made by Skype for SIP are:
  

  - PBX –> SkypeOut (PSTN)
  - SkypeIn/Online numbers (PSTN) –> PBX
  - Skype Clients –> PBX

• The business model, including pricing, has yet to be worked out. It will require Skype to determine a means to separate out business users from “consumer” users on both Skype for SIP and Skype for Asterisk. The principle here is that business benefits from the various features of these offerings; where such significant value-add exists there is a market for the services. But any pricing for either offering is yet to be determined, keeping in mind that both offerings’ desire to make significant market penetration will be a key moderator on pricing. Again quoting Chris:
  

  no new road is easy and enhancing our focus so Skype can support business users as a distinct group differently from consumers takes some work

• Differentiation from Skype for Asterisk will be an ongoing challenge. Initially Skype for Asterisk, which will be an Asterisk channel, includes handling SIP—>Skype calls, Skype-to-Skype calls and will incorporate presence information. (My comments on an ignored aspect differentiating these are below.)
• While SFS may incorporate some “Skype trunking” capability, SFS also offers the handling of inbound calling from Skype Online numbers.
• As for the current status of SFS, Chris says the focus at the moment is on getting voice connections right as this is the feature most demanded in the market:
  

  and this is baby steps for Skype, there are many more UC services to come, voice for SIP is the biggest ask from customers. Video/presence etc only make  sense when codecs are common between skype clients and SIP endpoints.Some work left there!

• Codecs are an issue. The initially supported G.729 codec requires licensing. The Skype for Business team is working on incorporation of G.711 within a few weeks but eventually hopes to assist with the adoption of the SILK codec across the industry by supporting SILK. But this also requires SILK support at the end points. Bottom line: codecs have both a technology and business issues to be resolved.
• Security is an issue that will probably provide one of the major challenges as Skype opens up access to its cloud from both Skype for Business offerings.

My own observations, not having been around for the discussion:

• Skype for SIP and Skype for Asterisk: the discussion yesterday centered on technical issues but totally ignored the market channel issues.
• Skype for SIP requires working with the various IP PBX vendors who have their own distribution channels; Skype for Asterisk is a partnering project with Digium who has its own unique distribution channels. These channels are both looking for innovation that keeps them in business. Yes, the common issue is that SFS and SFA both threaten the long distance market, but the VAR’s and System Integrators in these channels will need new offerings that meet this challenge.
• A significant challenge for both SFA and SFS will be the User Interface. How much will either of these products make the installation,  configuration and operational aspects so user friendly that outside support requirements are minimized or eliminated. This is a huge challenge in the SMB market as many small business owners will simply not want to be involved with such issues; they have their own business specialty to focus on. The value-add of VAR’s and SI’s serving any business market comes in making business communications low cost, seamless to the business operation and five 9’s uptime for their customers.
• There is not one solution that will meet the complete world of business needs. Currently in this SMB space we have several vendors: Cisco, Microsoft Response Point, Avaya, Siemens, etc. The world would be up in arms if there were only one offering for providing the disruptive innovation for which Skype can provide support to these channels.
• The issue of addressing consumer users vs business issues recalls the PC market twenty years ago when PC hardware vendors, initially Compaq, finally figured out how to differentiate and address these markets. This was a major issue I had to deal with in setting up a PC reseller network at the time. Today we see Dell addressing these various markets as soon as you launch into their website.

The Skype-enabled world is only healthy if there are alternative offerings and channels. Recall the theme of Skype President Josh Silverman’s reminder to the analysts last week: “Skype is a software company but we plan to be everywhere”. The Skype for Business group is focusing on making the software required to support these offerings; this software will leverage the IP PBX vendors and Digium distribution channels to drive adoption through into the various regional business market channels worldwide.

Update: While Om’s post, Skype Now Means Business, Friends the SIP World, demonstrates that he has not been following very closely the strategy being laid out by Skype’s new executive team over the past few months, the comment stream it triggered  is well worth reading. For instance, check out SFA developer Tim Panton’s comment about the opportunity for innovation he has found in SFA:

That aside, I’m a huge fan of S4A and our experience to date has been positive. We leverage the improved identity management (vs PSTN or SIP) and low costs of Skype to do some very cool integration with business processes and web applications by routing Skype calls through the extensible and scriptable platform of Asterisk.

• Skype Taps ShoreTel for Enterprise Play (gigaom.com)

Over the past eight months 1.2 million Skype users have participated in the Skype for Windows 4.0 beta program (stage 1, stage 2, stage 3). During this beta period, not only current user feedback was sought but also feedback from new users installing Skype for the first time. The goal was to provide a user interface that was more intuitive while encouraging users to go beyond simply voice calls to experience and use chat and video conversations.

Today Skype is announcing the Gold release of Skype 4.0 for Windows. From the download page:

We’ve built this brand new Skype so you can have the conversations that make a difference to you, every day. It’s easy to use, plus step-by-step guides help you get started.

While most of the new features have been revealed during the beta period, Skype’s marketing will focus on three key features:

• New user interface; with over 25% of Skype-to-Skype calls involving video this new release has been designed with a focus on improving the video call user experience.
• Improved call quality: Skype 4.0 for Windows incorporates Skype’s new SILK codec whose features are discussed in a separate post today. Bottom line is a crisp, crystal clear audio experience, yet only half the network bandwidth of other codecs is required to support a voice call.
• Bandwidth management: a new bandwidth manager has been developed with the goal of improving overall call performance by adapting, in real time, to degraded or low speed network conditions, such as those caused by excessive packet loss and/or jitter.

The new user interface also has taken into account factors that encourage users to explore Skype beyond voice calling. Incorporating beta user feedback Skype has found that the new UI is driving up adoption rates for Instant Messaging, file transfer and video. When you open a contact window launching a voice, chat or video conversation requires a single click on the respective voice (“Call”), chat or video button. The associated text pane tracks not only chat messages but also voice and video call detail information (launch time, end time) as well as file transfer information. And, as in the past with chat, the entire record is all archived on your local PC for future recall.

Other features: You can choose to view your Skype activity in one larger screen or in individual “conversation” windows. During a call a drop down menu on the “call audio control bar” provides quick access to making any necessary audio or video settings. Single click buttons allow you to quickly change oe add conversation modes to adapt to the context of the conversation. A wizard provides assistance with testing audio and video settings. During their testing they found that these features drove new users to more quickly experience chat and video while there was an increase in usage of these modes by legacy users.

On-the-fly the bandwidth manager can adjust both video and audio transmission by making real time adjustments to parameters such as video resolution, frames-per-second or audio bandwidth. to ensure an ability to maintain a basic level of communication while enduring these conditions. Once again the goal is to improve the overall user experience with no user intervention required.

Two changes;

• The SkypeMe! status button has been removed as a result of its tendency to be used for spamming and other forms of unwanted calls. (Of course you also still have the option to only allow callers in your Contact list to call you.). Along with this Skype has introduced “abuse reporting” which is monitored by Skype personnel for dealing with undesirable calling activity.
• While you can still participate in Public Chat sessions launched or joined from Skype 3.8, there is still no ability to launch or join a Public Chat from Skype 4.0 for Windows. This is my primary complaint about the new user interface. We have had a Skype 4.x Public Chat discussion ongoing since May, 2007; it has provided an interesting dialogue amongst Skype users and Skype personnel, including some feedback on features in Skype 4.0. And is has supported many other informal “water fountain” conversations amongst special interest communities of Skype users. Skype for Windows Product Manager Mike Bartlett claimed yesterday, during an interview, that Skype was reviewing how to embark on “public conversations” in today’s messaging world where services such as Twitter and Friend Feed also provide ongoing dialogues. However, Skype Public Chat has its own “space” in terms of user community; it needs to be brought back as soon as possible.

Over the next few weeks, with more experience using Skype 4.0 for Windows we may cover some features in more detail. In the meantime you can download it here. We look forward your feedback in the Comments. Release Notes are here.

Yesterday Skype went past 16 million concurrent users around 1830 GMT. It will be interesting to monitor both the concurrent user number and Hudson Barton’s “real user” indicator as Skype 4.0 for Windows installations grow over the next couple of weeks..

Of course, the best news is that Skype-to-Skype calls (including multi-party calls), chat and video calling remain free. And there are calling plan subscriptions available for low cost calling to landlines worldwide.

While there has been lots of dismay about the discontinuation of Skypecasts (Skype’s blog posts: here and here), it had appeared for the past several months that the service just did not have the robustness to provide the reliability and quality of service that users would expect. Being a free service, it was obviously placing resource demands with zero revenue potential on Skype developer and support personnel that hopefully can be diverted to bringing feature equality to Skype’s basic service, whether on Windows, Mac or Linux.

There are alternatives; in fact, this decision provides a unique opportunity for two third party conference calling services:

1. Skype Multi-Party Calling:

For up to 25 participants on a call, Skype has recently expanded its multi-party calling capacity. The caveat here is that the host must use a multi-core Windows PC and a reliable broadband internet connection (preferably cable). Participants can be on any version of Skype or be accessed via SkypeOut. In this case the host must set up the call and call out to all the participants. More details here. A unique feature of Skype’s multi-party calling is its ability to show which participant is actually speaking at any given time. But keep in mind Skype really offers multi-party calling, not a full conferencing service.

2. iotum CalliFlower

iotum’s CalliFlower has the benefit of no charge other than whatever it costs to make the connection to one of their access points. I often participate in their daily SquawkBox call via my SkypeOut account; the recent availability of SkypeOut CallerID, displaying my mobile phone number when I make a SkypeOut call, has allowed me to participate in these calls within my SkypeOut subscription without even using the provided password for each call. In fact, there are four options for accessing these calls:

As an example of building communities, iotum has worked with Alan Hunkin to provide a weekly interview session, CalliFlower Communiques, with notable personalities such as William Shatner. Immediate future guests include Ken Blanchard, author of “Being a One Minute Entrepreneur” and actor Alan Alda discussions his recent memoir “Things I Overheard While Talking to Myself.” Recordings of previous sessions are available at the page linked above.

3. HiDef Conferencing

Vapps’ HiDef Conferencing (formerly HiSpeedConferencing) provides high definition (HD) voice quality calls for participants accessing via Skype. Their business grade service involves fixed rate monthly hosting subscriptions involving unlimited Skype access, dial-in to specific numbers in several countries and toll-free numbers. Obviously this involves some ongoing expense to the host but their infrastructure supports providing the best possible voice quality, depending on access mode. The host uses their web controls to set up calls, manage call participants as well as record and archive calls.

Looking at the options it appears the best conference experience comes when:

• hosts are able to setup and fully manage the calls, including an open access invitation;
• users can participate through a web-based experience not only via voice but also via chat.

The good news is that Skype provides either free or low cost unlimited access to any of these services. What will be most interesting is to see if iotum and/or Vapps rise to the opportunity here and and is able to provide encouragement to the many communities that were supported by Skypecasts.

Over the past few months I have had reason to host, or participate in, voice calls involving more than two parties. Product demonstrations, daily Squawk Box sessions and weekly “broadcast” calls involving 200 or more participants have become part of my routine. But each is a different type of multi-party call.

Yesterday, along with several of my Contacts, I was involved in a test, initiated by Borderless Communicator’s Hudson Barton, of several of these services:

• Skype’s “Conference Call”: hosted through the Skype Windows/Mac/Linux client where a Skype user can host a Multi-Party call but use of the term “Conference” call is a misnomer. Free for Skype participants; SkypeOut charges apply to participants on the PSTN. Up to 25 participants
• HiDef Conferencing: hosting business grade conference calls with a user management interface operated by the call’s “moderator” or “host”. Monthly subscription required to host; unlimited free access for Skype participants; toll charges may apply for participants calling in via the PSTN. Up to 500 participants
• iotum Calliflower: again hosting a multi-party calls that can be managed by a “moderator” or “host” party. “Free” participation; however, participant responsible for any toll charges to reach Free Conference Call server, and
• Skypecast: a Skype service for hosting public “voice chat” rooms where participants can discuss a topic of interest. Public access; free but only accessed as a Skype user; no PSTN participation. Up to 100 participants. Popular use: learning English at Kantalk.

I can see four types of multi-party.calls:

• Ad hoc multi-party calls, such as what is misnamed Skype Conference Call. Informal, host can easily add/remove participants, but no other participant management features. All participants are active; no agenda (think the “UNconference” call)
• Conference calls which are often scheduled, usually have an agenda and where participants are all active but can be managed by the host (and/or other designated participants).
• Broadcast calls, such as training presentations, news and analyst conferences, large audience sales presentations, etc. where there is a call administrator and usually one or two active participants who will make a presentation to an audience of several hundred or even a thousand passive participants.
• Public voice chats, such as Skypecasts where any Skype user can join provided they find the link (either by email or text chat invitation or from a directory of Skypecasts).

While all these types of calls use technology that merges the various voice streams to be heard by all participants, the user interface and degree of active participation are the key differentiators:

• Ad hoc multi-party calls: you can host a multi-party call simply by selecting multiple Skype and/or SkypeOut contacts and starting what is labeled as a Skype Conference call. If you see a need to add another participant, either add a Skype/SkypeOut Contact or call up an additional SkypeOut number. The host can also remove participants from the call at will. In yesterday’s call we had excellent HD Voice quality, we could see who was speaking (see halos around Dan and Hudson, only is Skype for Windows) but individual participants manage features such as muting their own microphone. You can definitely detect who is on a SkypeOut connection due to the more limited audio bandwidth of a SkypeOut connection. Since the host is operating the call through his/her local PC, these quality of these calls can also be subject to variables such as the host’s CPU power and Internet connection (especially the upload speed). Good enough for consumers and internal business calls but definitely not business grade. In a different graphic format, .Skype for Mac lets you see who is talking, including individual volume levels. Requires third party product, such as Pamela or Skylook, to record a call.

Free Conference Call Participant View (pre-Calliflower)

• A true Conference Call is one where an administrator or host effectively “chairs” the call, has the option to schedule the call and provide an agenda, can manage each user’s level of active participation (mute/unmute, hand raising) and provide a hosted recording capability. Also these business grade calls are server-hosted to provide a consistent and manageable level of robustness and reliability as well as overall voice quality. Both HiDef Conferencing and iotum’s Free Conference Call have these capabilities.
  • While HiDef Conferencing provides excellent HD Voice quality for all participants connected via Skype and has a Host user interface to manage the call, it could use a web-based interface for participants to see who is on a call, who is speaking and provide a common chat “wall”. At one point during the test call, one participant went over to a PSTN connection and there was a very noticeable deterioration in his voice quality while on that connection.
  • iotum’s Free Conference call has the above-noted participant user interface features but is difficult to enter (while not a requirement, having a Facebook account makes it easier to access). Limited by its architecture to the legacy PSTN audio bandwidth, call quality is acceptable but not HD Voice. It had a significant call quality issue for one participant and needs a “Leave Call” button on the participant user interface. On the other hand iotum’s Free Conference Call has been shown to be robust and reliable enough to handle their daily Squawk Box conference call with relative ease; the ability to see who is participating and a chat “wall” are major benefits.
• In a Broadcast Call there are usually one or a few presenters while an audience passively listens unless they “raise a hand” to ask questions or make a point. When HiDef Conferencing calls get to the 100 participant level, it has usually become a Broadcast call. (In fact, VAPPS hosts the voice component of several other conferencing and meeting services, such as InstantTeleseminar)
• Our experience with the Skypecast trial today was one where there were significant difficulties joining the Skypecast (only four of our seven participants successfully got in) but where there was excellent voice quality. Limited participant management by host who can mute/unmite and eject a participant. Requires third party product, such as Pamela or Skylook, to record a call.

Some conclusions:

• Skype should rename their basic “Conference Call” to “Multi-Party Call”. Its service is effectively a multi-party scaling of my former Bell Canada “3-party call” service. The initiator of the call hosts the call on his/her PC and does not always have complete control over call quality and robustness of the call.
• Conference calls are hosted calls with “moderated” participant management. The key differentiator here is the user interface for both the host and the participants as well as the ease of call access by the participants. While the ability to link the voice streams of all the participants is common to all these services, overall call quality itself can be another differentiator.
• Hudson measured some call parameters during each call. Basically all services were in the same ball park for jitter and packet loss (none to <1%) – most participants connected to the calls via either Skype or SkypeOut; on the Skype Conference Multi-Party Call latencies were definitely related to the distance of the participant from my hosting connection.

While this blog tends to focus on new developments and the role they can play in our future real time conversations, it sometimes pays to look back to see what has been accomplished. For 2007, these are, from my perspective, top ten accomplishments for the Skype ecosystem:

1. eBay CEO Meg Whitman states at an eBay quarterly analyst conference call, “Not enough focus on ‘Delight The User’”. Hopefully this is a high priority guiding principal in the search for a new Skype CEO. Great technology but needs the business development, marketing and leadership skills of a seasoned high technology executive to truly make Skype happen on a world market leader scale. End users need a delightful “total” experience, including user support, adequate and well timed announcement of changes to calling plans, more participation in the blogosphere, higher awareness and broader availability of Skype hardware … and the list goes on.

2. Skype High Quality Video: because it brings a whole new dimension and level of realism to real time conversations. Yes, to take full advantage requires a new webcam with enhanced optics, but my final selection came because of the very positive reaction and response of those whom I converse with and who receive my High Quality Video (Recipients don’t need all the requirements of senders — the past two weeks two parties have observed “my” High Quality Video on their Macs.) A success story involving not only Skype software but also hardware specifications and co-operative device driver development.

3. HD Voice –nobody has called it that specifically but here I pick up a term used to name a Fall VON session. I refer to wideband voice transmission covering a minimum 8Khz audio bandwidth (twice that of conventional telephony). Over the year Skype has been making gradual improvements to the Skype voice engine, including the codecs, such that today most Skype voice conversations can be held with a basic laptop, and no additional headset or microphone (provided one is available in the laptop) is required. Over Christmas I helped my son with a Skype for Mac installation; he made a call yesterday from his home that was very clear using his basic Mac speakers and mic. Each new version of Skype since Skype 3.2 has had some improvements but with Skype 3.6 I am getting many unsolicited comments about how it better handles lower Internet connection bandwidth configurations. And, should you use a headset, such as the FreeTalk Wireless Stereo headset, for, say, personal privacy or office etiquette reasons, you will find your other parties on the call “in your head”. HD Voice received additional support this fall when HiDef Conferencing became equipped with the ability to ensure all Skype participants on a conference call would experience HD Voice quality when conversing with other Skype users on the same call.

4. Mobile Access to Skype. We still don’t have a Skype client for three of the most popular mobile devices (Nokia, Blackberry, iPhone); true mobile VoIP requires not only either WiFi or 3G connectivity but also appropriate wireless network infrastructure to handle the capacity demands VoIP would place on a wireless network. However, we have seen the release of several offerings that provide a combination of an IM client for these platforms along with a protocol that allows easy access to the wireless network to complete a call from a mobile device at reduced costs. These include the 3 Skypephone, IM+ for Skype (even works on not only the iPhone but also iPod Touch), iSkoot and Fring.

5. Skype Developer Partner acquired: Pioneering Skype Developer Partner Webdialogs was acquired by IBM’s Lotus Sametime division in September. Certainly says that with the right technology and offerings there is potential for other Skype developer partners to lead the way to expanding the Voice 2.0 world where applications are the value generator. Question: will IBM’s Lotus Sametime license Skype technology for their own real time conversations capability?

6. Skype Developer Platform. While still requiring web services support to be offering a complete mashup development platform, the Skype Mashup contest and announcement of the Skype Public Platform Roadmap have brought enhanced awareness to this program. Partner PamConsult has led the way in demonstrating, with PamFax, how Skype technology, digital rights management and transaction engine can be combined to offer a carrier independent, worldwide service that requires only a Skype user account, an Internet connection but no additional hardware beyond a basic PC.

7. Disruption Rules: While PamFax can reduce the cost of those $1.00+ per page faxes from hotels, two Skype Partners have introduced products that portend for significant business model disruption:

• OnState’s Call Center brings a “no hardware” solution to the call center space. Whereas a full call center previously required a low six figure investment in a PBX, as well as IT support and other infrastructure, OnState’s Call Center has the cost of a PC for each agent along with a $30 per month per agent ongoing subscription fee with no long term commitments.. Suddenly call centers become viable both for even the smallest business and for remotely located, geographically distributed employees.
• Vapps, Inc.s’ HiDef Conferencing provides hosted business grade conference calling (with HD Voice support as mentioned above) that is robust, reliable, scalable and supports up to 500 participants on a call. For as little as $25 per month to as much as $200 per month you can have 10 to 500 Skype participants with unlimited minutes as well as 300 to 5,000 toll-free minutes for callers from the legacy phone network. Six years ago $200 got me one hour of a five-party conference call. (Jan 2009 Update: HiDef Conferencing has been acquired by Citrix and is offering free trial calling until February 15, 2009.)

8. Innovation Rules. Whereas disruption requires the displacement of legacy business processes, innovation brings new services that allow new, previously unavailable (business) processes to happen:

• For instance, there is a Vosky distributor in Texas who has worked with a local social service agency to provide much more effective counselling services by bringing into the monthly review of “challenged” children’s education the child’s teachers located at the school during a social worker’s monthly visit to parents at home.via Skype conference calling.
• But we also are seeing innovative new services such as Evoca’s Media Service. This involves a hosted “Get a Phone for your Website” audio service that provides for asynchronous voice conversations being used, for instance, by Discovery Channel, with user access from either Skype or a legacy telephone.
• Collaboration: there are three different collaboration services, each addressing its own market niche. I label these services as innovative as they bring entirely new processes to business for both internal and external conversations, especially businesses that are geographically disbursed.

9. Skype Toolbars: For some time Skype has offered toolbars which make Skype calling more readily accessible in common applications such as Outlook, Internet Explorer and Firefox. In fact, the Skype Outlook Toolbar and Firefox extension have both become routine elements of my everyday communications operations. (Remember, I don’t dial phone numbers, I call people with real names.) Two weeks ago, Skype released a new version of the Skype Outlook Toolbar which has optimized Skype-enabled operations within Outlook while eliminating a couple of “nuisance” bugs in the previous version. However, the browser toolbars became embedded into the standard Skype installation but should you elect not to install them, you now have to re-install Skype itself. This is one example where Skype needs to “Delight the User” by restoring the ability to install these Toolbars individually when they were not installed at the time of Skype installation.

10. Skype Public Chats: Since first introduced in May, I have been a participant on several group chats, the most enduring being the Skype 3.x Discussion chat where several Skype enthusiasts share their thoughts and ideas. One interesting aspect of this particular chat is that a few members of the Skype Developer team and Skype PR people monitor the session and, when appropriate and not in conflict with “company policy”, participate in the conversation as well as provide notification about new releases, etc. It was a rather heated discussion on this public chat that lead to this Skype Journal post about restoring a “geek” feature buried in Skype related to Skype video. Another Public Chat was open during the beta testing of the Skype Outlook Toolbar; no doubt its input, and ability to bring out common issues, contributed to the robustness of the newly released Skype Outlook Toolbar.

11. (I can’t stop at 10): And for the 11th accomplishment: Skype Technology Licensing: In my recent interview with Sten Tamkivi, GM of Skype Estonia (a detailed post to follow), he mentioned that Skype is migrating its development focus to becoming a platform developer from simply a client and services developer. In addition to a platform for Partners (discussed above), the recent licensing to MySpace is the first in the series of what they hope becomes Skype infrastructure technology licensing deals with other services as their route into, say, providing social networking infrastructure.

From my perspective these have been the top accomplishment within the Skype ecosystem in 2007. It has resulted in a cost effective conversation ecosystem that has no equal amongst VoIP service providers. However, this ecosystem is not near demonstrating its full potential; hopefully eBay will announce a new CEO soon who captain the ship into providing a “delightful user experience” at full sail.

Ever since eBay’s acquisition of Skype over two years ago, there has been speculation as to how eBay and Skype should be “integrated” to enhance the auction process. While not the world’s most active eBay participant, I have used it several times to acquire items not normally available in Canada and to sell (ironically) a “surplus” Nortel PBX a few years ago. But I have also had the opportunity to attend a couple of eBay Live events and gain some of the flavor of the extent of the Ebay domain and the enthusiasm of its resellers, especially the several hundred thousand who run a full time business through eBay.

During these eBay Live sessions I have noted two key facts:

• There is very little Skype awareness amongst the eBay reseller community.
• When one or two Skype training sessions are available over the three days of eBay Live, they are well attended with an eagerness to learn more about Skype

My primary question has always been, how would one maintain the integrity of the auction process while engaging in real time conversations. It appears there are several stages to the auction process:

• Setting up the individual item’s auction information
• Executing the auction, accepting bids and “Buy Now” requests
• Finalizing the payment transaction
• Delivering the item, and
• Exchanging buyer and seller feedback.

The key for the first two stages is to enhance the integrity of the auction itself by ensuring that information exchanged between seller and bidder is available to all potential bidders. Real time one-on-one Skype chat and voice conversations have the potential to violate the integrity sought. Yet, with Skype there are two solutions:

1. Establish a Skype Public Chat that can be joined by any bidder who is on Skype; the reseller can manage who remains on the chat to eliminate “spammers” and others wh go off-subject..
2. Establish an ongoing asynchronous voice conversation using Evoca’s hosted voice recording and playback services. This allows all (potential) bidders to have an asynchronous, ongoing conversation with the seller incorporating all the additional information disclosed as a result of bidder queries..

For the last three stages, standard Skype conversations (voice, IM chat and video) can be used to provide customer service and support, as appropriate to the individual auction. Should their business be ongoing with sufficient transaction volume, even OnState’s ACD Call Center solution can be invoked (at $38 per seat per month – no capital costs) to ensure calls are directed to an appropriate party.

But then there is a bigger challenge beyond simply installing Skype and creating Skype accounts: training eBay Resellers on how they can implement and use Skype to their business’s advantage. It is not sufficient simply to make Skype buttons available for eBay Resellers. The Skype ecosystem not only offers basic real time conversation support but also, through its Skype Developer Partners, call recording and conversation archiving as well as collaboration and conferencing tools which may be useful for certain categories of resellers. But they need training to realize the full potential of Skype.

And then there is the missed viral opportunity yet to be fulfilled.

Dan York, over at Disruptive Telephony and a permanent participant in the Skype 3.x Discussion public chat, has just pointed us to Skype’s announcement that the limit for participants in Skype Public Chats has been raised to 150.

Dan is perplexed (and I am also) as to why we often see the actual number of participants is over the limit (whether 100 or 150). At 8:56 EDT this morning he saw (using the “/info” command in a Skype chat client) 201 “members” on the chat, yet less than an hour later I get only 83. Did 118 members sign off within an hour? (FWIW, I am running Skype 3.2.0.158.) Seems like the counter is having some difficulty. Or is it another “real time presence” issue?

BTW, if you use Pamela and upgrade Skype to this build (3.2.0.158) make sure you also upgrade Pamela to its latest version 3.5.0.54.

Yesterday Skype released its initial Skype for Windows 3.0 beta with several new features. However, the press release does not really show the entire picture and, in fact, two of the four features mentioned were available in the previous 2.6 beta – namely, Click-to-Call and Skypecasts Live. Click-to-Call is simply an embedding of the previously available Skype for Web Toolbars supported by the Phone Number Recognition COM-component. It is a very handy feature that I have been using for some time.

But the other two — Public Chats and a User Interface refresh — bring some significant changes:

Public Chats — my first activity was to walk through the Public Chat setup wizard. But I quickly realized it should be called the Skype Watercooler. The algorithm allows you to control who will participate; you can invite via emails, chat session or via a web page. You can control if a participant is active (able to contribute to the discussion) or passive (can only read the discussion). Lots of flexibility here. Whereas Skypecasts are publicly exposed such that anyone can join, the level of participation here is determined by the level of exposure you provide for your invitation.

But most interesting is to get the experience that comes from the persistence of a public chat. Yesterday I joined the Skype 3.0 Public Chat started by Phil; this morning when I came to my PC I could quickly review all the conversation that had occurred overnight (hey, those Europeans start their day early). Skype’s Public Chat will become an interesting tool within the social networking landscape but Skype Marketing needs to look at a more definitive, attention grabbing name for the service. Let me say it again: Skype Watercooler.

User Interface: Lots to talk about here but I will just highlight some features:

The first one that grabbed me eliminates one of the frustrations associated with answering Skype calls on PC’s containing multiple Sound Devices, namely, the incorporation of Sound Device settings into the Call Tab that comes up during a call. Click on the headphone icon on the right, above the Address Bar, and the Sound Devices menu shown appears allowing you to make a change without having to do the Control Panel | Sound Devices routine.

However, that “Windows Default Device” setting for my configuration allows my Sound Devices selection to automatically change when I pick up/set down my VoIPvoice enabled phones. I would like to see a stand alone Sound Device utility that provides the additional flexibility I need to switch between my headset (on an internal sound card), my USB speakers (for SlingBox and Windows Media Player) and my VoIPvoice phone configuration, but keeping the feature that automatically switches to my VoIPvoice drivers when I pick up a VoIPvoice device.

The blue button below the speaker setting provides one more speaker volume control; the control below the mic device selection can also have a blue ball — read about it in Jaanus’ post on Sound Device selection; however, you need his solution only if you have significant difficulty with your mic operation.

Tabs: A major UI change is the use of Tabs such that operating icons only appear within the appropriate tab. For instance, the Contacts Tab is the primary location from which you would launch a Search or a Conference call, so they are demoted to a secondary level in the primary Toolbar. Overall the new Tabs reduce Toolbar clutter while maintaining ready access to key features; reminds me of the move a few years ago to the more extensive use of Tabs in Windows XP.

Check out Duncan’s post for more information on the new UI covering Tabs, Contacts Tab, Calling functionality and (personal) Chats.

Extras Gallery: Here we see the initial implementation of the Skype Plug-in framework linking individual third party Skype-associated programs with Skype users via the Skype client. But more importantly we can start to see how Skype plans to provide a marketing vehicle for developers’ innovations. With direct access from the Skype client, these Skype related programs gain more visibility than simply via the Skype web store. The next obvious step would be to facilitate purchases using Skype credits (which can be purchased via PayPal). The challenge will be cataloging and displaying these partner programs in a user friendly, readily accessible manner as the number of available plug-ins/programs scales.

This is by no means a complete summary of all the new capabilities and “hidden” features. More will follow as we gain more experience. And keep in mind, this is still a beta although we’re hearing the target for a gold release is before year end. While my network of contacts says it is quite solid we’re still finding (and reporting) subtle bugs and issues. In fact, it is interesting to note that some are being picked up and communicated via the Skype 3.0 Public Chat referenced above; our thanks to those Skype employees who have joined this chat from time-to-time.
