Creating voice applications that interconnect with Skype and SIP

voxeologo.gifGiven that I write on Voxeo's blog site, I tend not to write much here about things we are doing at Voxeo.

But I thought I'd mention here one specific post I put up recently called "Skype-ifying your voice applications" which talks about the intriguing ways in which you can use our hosted platform to make voice applications accessible through a number of different mechanisms.

voxeo-inbound-outbound-1.jpgAs shown in the diagram to the left, an application that you write and is hosted on our platform can be called into over the PSTN, over a direct SIP connection or via Skype or FWD. Likewise calls can go out to PSTN numbers or to SIP endpoints.

This flexibility is one of the many things that intrigues me about the platform (of which I knew nothing about prior to joining the company in October).

Anyway, more information is in the full blog post. I just thought I'd mention it here. (By the way, if you'd like to try it out yourself, developer accounts are free.)

Nortel's fascinating move into open source telephony... but NOT with Asterisk

nortel.jpgNortel and "open source telephony"? Huh?

That was admittedly my thought when I received the list of who was going to be on the panel I moderated last week at VoiceCon on open source telephony. The other two panelists were obvious choices: Bill Miller was from Digium (makers of Asterisk) and Raza was from 3Com who have recently announced that they would be reselling a version of Digium's Asterisk Business Edition. Both Bill and Raza made sense to me. But Tony Pereira of Nortel? Nortel does not leap out at me as a company working with open source telephony - what in the world are they doing with it, I wondered?

It turns out that the answer is... "quite a bit!"

As Tony Pereira outlined in our panel as well as in conversations afterwards, Nortel is in the process of launching their "Software Communications Server 500" (SCS 500) targeted at small businesses and built using open source telephony software!

Interestingly, though, it does NOT use Asterisk.

sipfoundry.jpgInstead Nortel is using the "other" major player in open source telephony, the "sipXecs" product from SIPfoundry.org. (Previously called "sipX" but renamed "sipXecs" about a year ago.) I've not written all that much about sipX here but it certainly has been a product I've known of over the years. It started out as a PBX product from Pingtel which they then released as an open source version ("sipX" and now "sipXecs") and also had a commercial version called "SIPxchange". sipX garnered perhaps its most attention back in October 2006 when it was announced that Amazon.com would be using it for their internal phone systems (see the links on the SIPFoundry.org site). At a fundamental level, sipX provides similar functionality to Asterisk but where Asterisk is focused on being a "platform" for telephony that can work with a wide range of protocols, sipX is focused exclusively on SIP and also provides an extensive GUI management tool. (Pingtel provides a (obviously biased) comparison of sipXecs vs Asterisk on their wiki.)

From what I learned at our panel, Nortel is essentially creating their own supported version of "sipXecs" that they will sell as the "SCS 500". It will have full commercial support from Nortel. Target market will apparently be "small" businesses. No info really available on Nortel's site yet, although glimpses are visible through support documents (such as here and here(although this appears to be about an earlier 1.0 version last year)).

All in all it's to me a fascinating move by the folks at Nortel and I look forward to learning more about the SCS500 product over the next weeks and months as they launch it. It's a rather nice boost for the whole world of "open source telephony", too, to have Nortel making this move as well.

How do YOU see social networking changing enterprise communication?

1F986311-DE40-482A-B982-3300FE408328.jpgHow do you see "social networking" and "social media" changing communication within companies, enterprises, etc.? How do you think blogs, wikis, etc. will change enterprise communication? What about Facebook and other similar sites?

What would you say on this topic to an audience at VoiceCon Orlando this week?

That's the task ahead of Irwin Lazar and I as we talk with Eric Krapf and Fred Knight in a keynote "conversation" from 10:30-11:00am on Wednesday. The panel, called "Social Networking Meets Enterprise Communication"has this for a description:

It's no secret that world of enterprise communications is undergoing a transformation; IP Telephony and Unified Communications are changing the nature of the game. Now new forms of interaction, which began in the consumer/personal communications market -- blogs, wikis and online services like Facebook are migrating into the enterprise. Where do these social networking systems and mindset fit into the enterprise communications landscape? Join us for a discussion about what's real today and what's likely to happen in the future.

Obviously, this is a topic about which I am rather opinionated and have been writing about in my various blogs for years (including this blog, as well as on Disruptive Conversations and in my reports into For Immediate Release), so I'm very much looking forward to the session with Irwin on Wednesday.

We've already got a long list of points we can cover... and obviously won't be able to cover them all in only 30 minutes (and we've got a hard stop at 11am as what's next is a presentation with Al Gore and Cisco CEO John Chambers!). But I thought to myself - how can I do a keynote panel on the impact of social networking in enterprise communication if I don't somehow include social networking into the prep for that panel?

So here's my question for you all -

What do you see as the top one or two ways that social networking / social media will change the ways in which people communicate within enterprises?
Both internally among employees and also externally between the company and its customers and partners?

To perhaps get the conversation going, here are a few of the topics that Irwin and I already have in our list:

  • interest in the opportunities to improve collaboration among employees, especially virtual/distributed
  • interest in the opportunities to improve collaboration with customers and partners/vendors
  • concerns over enterprise usage of public sites/services, i.e. what security is there for corporate data out on these sites?
  • challenges with rolling out these services internally (from a deployment point-of-view as well as business case, who owns it, integration of different systems, etc.)
  • expectations of new generation of incoming workers
What do you think? How do you see social apps/services changing enterprise communication? (Or do you take the contrarian view that it won't?) Your feedback is definitely welcome... (thanks in advance)

My presentations at VoiceCon this week...

1F986311-DE40-482A-B982-3300FE408328.jpgI'm down in Orlando this week for VoiceCon Orlando and will be part of three sessions. Tomorrow, I'm moderating a panel at 8am on VoIP security and on Thursday I'm moderating a panel on open source telephony. On Wednesday, I'll be part of a keynote panel with Irwin Lazar on "Social networking and enterprise communication", which should be quite fun. I'll include below the full descriptions of the various sessions. If you are attending VoiceCon and want to connect, please do contact me.

Session Title: Top VOIP Security Threats
Date: 3/18/2008
Time: 8:00 AM
Room: Osceola B
Session Description: There's been a lot of concern about voice over IP security, but have there been many actual exploits? This session will inform you about the state of VOIP security. You'll learn about generalized IP attacks that have affected IP telephony systems deployed on IP networks, and you'll also find out what VOIP-specific attacks have actually been observed "in the wild"--and what to expect in the future.
KEY QUESTIONS: * What are the most serious voice-oriented attacks that are actually being carried out? What potential attacks haven't occurred yet but probably will before long? * How do you protect your VOIP systems against these attacks? * What types of equipment and technologies must you implement to stop voice-oriented attacks? * What specific kinds of damage can these attacks cause?
Moderator(s): Dan York - Dir of Emerging Comm Tech - Voxeo
Panelist(s): Sachin Joglekar - Vulnerability Research Lead - Sipera Systems

Session Title: Open Source for Enterprise Voice: How Much, How Soon?
Date: 3/20/2008
Time: 11:45 AM
Room: Sun C
Session Description: Open source PBXs are gaining a higher profile: Asterisk and other open-source PBX software packages continue to gain acceptance, and some traditional PBX vendors have implemented open source code for their products. But these efforts still aim mainly at smaller implementations. In this session, you'll learn why open source PBX software has growing appeal, and whether it will appeal to larger customers as the market progresses.
KEY QUESTIONS: * What level of market share and acceptance has open source PBX software attained? What is expected? * Which products use open source PBX software? * What are the most compelling reasons for choosing open source PBX software? What are the greatest areas of concern in making this choice? * What are the technical challenges of an open-source PBX deployment, and how are these overcome? * What are some real-world customer experiences with open source PBX software?

R.I.P., Russell Shaw, VoIP blogger for ZDnet

A876A2AC-FF07-4758-BF29-9765A305180C.jpgA little bit ago, Andy completely surprised me with a call via Skype (it was 8pm-ish on a Saturday night and I just happened to be at my computer printing out boarding passes for tomorrow's flights) with some terrible news.

As Andy relays in his blog post, fellow VoIP blogger Russell Shaw passed away suddenly in his hotel room in San Jose sometime over the past couple of days. Russell was out there to attend eComm 2008 and Andy said that several folks were wondering where he was as he never made it to the actual show.

I've enjoyed Russell's writing on his IP Telephony blog at ZDNet and while I never really worked with him in any way, I would often run into him at the various VoIP conferences (and often at Andy's famous dinners). He was "one of us"... those who choose for whatever reason to write about VoIP/IP Telephony/Unified Communications/whatever... and so it is definitely sad to learn of his passing.

My thoughts right now are certainly with his family, wherever they may be, as they come to grips with this very sudden change.

Rest In Peace, Russell... you will definitely be missed!

P.S. ZDNet's Editor, Dan Farber, also has a nice post up about Russell.

The Oprah-tization of VoIP via Skype!

6562BA82-E145-4494-8CE7-854A04CA3AF5.jpgDid you ever think that we would utter "Oprah" and "VoIP" in the same sentence?

Well, we are... or more precisely "Oprah" and "Skype". If you have no idea what I am talking about, you need to head over to Skype Journal and read Jim Courtney's piece: "Skype Sponsors Oprah's 'A New Earth' Web Event"

Essentially, Oprah has taken her Book Club online to host a weekly web collaboration session for the next ten weeks with, oh, 750,000 members of her club! More information - and an audio introduction from Oprah - is available on the Skype campaign page. Monday night was the first first session and as Jim subsequently noted (as did Howard Wolinsky on the new Skype US blog), the session didn't go so well with regard to technical issues. As Oprah's company, Harpo Productions (Hint: spell "Harpo" backwards) said in their statement:

Monday night's webcast was one of the largest single online events in the history of the Internet. More than 500,000 people simultaneously logged on to watch Oprah Winfrey and Eckhart Tolle live, resulting in 242 Gbps of information moving through the Internet. Unfortunately, some of our users experienced delays in viewing the webcast. We are working to identify the specific causes for the problems experienced and will work diligently to rectify them.

252 Gbps, eh? I think that's bringing new meaning to "disruptive telephony/communication!" I'll have to ask next week at IETF-71 if anyone there ever thought we'd see that kind of throughput! Pretty cool, on one level, but it obviously taxed the Internet a wee bit - or at least the connections into the servers running all of this. They go on to say:

Harpo Productions, Inc., Move Networks and Limelight Networks recognize that interactive Internet broadcasting to a mass audience is still an emerging medium

Yep!

But as Jim notes in his post, there are some definite wins for Skype here. Apparently the Skype portions of the web conference, which involved people asking questions over Skype High Quality Video, worked very well. There were also apparently some great statements from Oprah about how great she thought Skype was.

Kudos to Skype for getting in there in such a massive event - I can honestly say that I never would have thought I'd be writing about Oprah here. It will be interesting to see how the subsequent sessions go.

And for all us who are not joining in - for the next 9 weeks, Monday nights are probably a good time to stay off the Internet! (You know... read a book... play a game... go for a walk... ;-)

I'll be down at VoiceCon Orlando in March 2008...

No Jitter |.jpgFYI, I will be down at VoiceCon Orlando on March 17-20, 2008. I'm moderating two panel sessions (see the schedule). First, up, bright and early at 8am on Tuesday, March 18th, I'll be moderating a panel on "Top VoIP Security Threats". This should be a fun one as it has VOIPSA Chair Dave Endler, Mark Collier of SecureLogix and Sachin Joglekar of Sipera Systems. I know all three of the guys, particularly Dave and Mark who have both worked on VOIPSA matters, and this session should be a good bit of fun. I'm planning on making it a rather interactive session. :-)

At the other end of the show, on Thursday, March 20th, at 11:45am, I'll be moderating a panel "Open Source for Enterprise Voice: How Much, How Soon?". This would should be interesting because it has Bill Miller from Digium (makers of Asterisk), who I know well, and M Raza from 3Com... and then Tony Pereira from Nortel! 3Com's presence on the panel isn't particularly surprising given their relationship with Digium, but it will be interesting to see Nortel's view on the matter.

All in all it should be quite an interesting show. Lots of good sessions and, I'm sure, interesting people to meet. If you're going to be down there, please do drop an email as I'm always interesting in meeting readers of the blog.

Congrats to Skype on hitting 100 BILLION minutes!

skype_logo.pngA huge congrats to Skype for hitting the milestone of over 100 BILLION minutes of Skype-to-Skype calls! As Skype's Villu Aruk notes in his amusing post, it's rather hard to wrap your head around numbers of this size. Congrats to all the folks involved with Skype... it is a milestone to celebrate.

See also Jim Courtney and Jon Arnold with their views of this announcement.

The EComm 2008 Interview with Skype's Jonathan Christensen should be required reading...

42F19C6B-67C5-433E-91B4-641B9323CD48.jpgAs we enter into the final month before eComm 2008, I would suggest that the interview with Jonathan Christensen, Skype's general manager of audio and video, should be required reading for anyone seriously interested in this space. Why? Well, in part because Jonathan Christensen does provide some good information about what Skype has done and is doing but also because it provides some good insight into what one of the people driving Skype's agenda is thinking about this space. Take one of the final paragraphs where he answered Lee Dryburgh's question about what he saw as the the future of communications (bold emphasis added by me):
Well, a big question I guess and, having worked on the space for quite a while, I think that it's only going to get more interesting over the coming years since, well, like this open spectrum for example. You know, I just have to reiterate, I think that anybody who has not figured out that the Internet is the platform and that there isn't any such thing as walled gardens that will survive, or sub-networks [such as AOL tried] that are going to survive, those people are doomed. The intersection of these worlds is going to be chaotic. It's going to be violent. It's going to be messy for a while but it is going to happen, and the Internet will survive as the one open platform. You are going to see a trend towards extreme innovation at the edges - on the devices, in the PC platform, in software, all around the edge of the Internet.

I think that you are only going to see further disruption of the telecom industry and the emergence of totally new businesses that we can't imagine today. I think that [the] net result, that drives me every day, is that we're going to have this very rich, open, cheap and accessible communications. This is going to be not just a game changer for the telecom industry, but will be a change agent for all of humanity. So, a platform that allows us all to see each other and hear each other more clearly maybe makes us a little bit less crazy, less polarized and more open as a world society.

Good stuff... and the whole interview is worth a read. Given my recent criticism of Skype, I'm particularly pleased to read the comments I emphasized in bold. Jonathan Christensen will be giving one of the keynotes at eComm 2008, March 12-14 in Silicon Valley and if you haven't considered going, I would encourage you to do so. It should be a great event!

P.S. I also wrote about this interview in relation to SIP over on Voxeo's "Speaking of Standards" blog.
