Disruptive Telephony

Has Asterisk NOT "crossed the chasm" for developers? (Key links to read for open source)

Jay Phillips is frustrated. He passionately wants to see open source telephony enjoy success all around the world. Yet right now, when people think "open source telephony", they almost always think of Asterisk... and Jay sees too many challenges for developers embracing Asterisk. Jay, the creator of the Adhearsion telephony framework for Ruby, has spoken about this at recent conferences and pulled together his thoughts in a lengthy post earlier this week entitled "What We're Not Admitting about Asterisk".

Jay argues that Asterisk has not crossed the proverbial chasm for developers and outlines some of the issues he sees.

What is perhaps most interesting about Jay's post is the equally lengthy response by Asterisk creator Mark Spencer. Mark responds to Jay's various points and in doing so provides some good insight into his views on Asterisk's connections to developers, APIs, etc., as well as the differences between the markets that Digium, the company, goes after versus the "market" of Asterisk, the raw telephony platform.

Both Jay's article and Mark's response are definitely worth reading. I'm friends now with both of them and they both bring immense passion and energy to the world of open source telephony. Ultimately they both make the point that we need better tools for developers to create voice applications. This kind of dialogue is great and will only result in better tools in the end. Please do check out the posts.

P.S. Thomas Howe has also weighed in with a post saying this is a clash in world views, which also makes for good reading. I agree with Thomas that we are in a transition into a world of "web-as-a-platform"... basically a transition "into the cloud"... and so we do need "web-centric" interfaces and APIs. But I disagree with Thomas that Asterisk is "tired". To me, Asterisk is just... well... "plumbing". Asterisk is a telephony platform, as is FreeSWITCH... as is Yate... as are all the commercial IP-PBXs. Asterisk is an open source component of the rewiring of our communication infrastructure that we have underway right now. I think anyone, including Mark, would agree that Asterisk has technical challenges it needs to overcome but I, for one, am not ready to write it off yet.

FYI - I'll be out at OSCON next week in Portland talking about voice mashups...

If any of you reading this will be out at O'Reilly's OSCON Open Source Convention next week (July 21-25) in Portland, Oregon, I (Dan York) will be there giving a talk on Wednesday on "Mashing Up Voice and the Web Through Open Source and XML". Here's the abstract:

With over 4.5 billion mobile and fixed phones out there as of November 2007, the phone represents the most ubiquitous user interface out there. As “mashups” on the Web let us quickly and easily access information from multiple data sources, how do we extend those mashups to the world of the phone? How do we bring the old world of voice and telephony into the new world of the Web, social networks, and social media? And how do we do that using open source tools and open standards? In this session, Dan York will introduce participants to the world of “voice mashups” and how applications can be quickly built on top of open source and open standards. Topics covered will include:

• The technology and architecture behind voice mashups
• The open standards in voice of VoiceXML, Call Control XML (CCXML), the Session Initiation Protocol (SIP), and new standards emerging from the Internet Engineering Task Force (IETF)
• Open source tools related to voice including Asterisk and RocketSource.org
• How to quickly build voice applications that interact with web sites, databases, and even new services like Twitter.

During the session, York will demonstrate multiple applications and provide participants with sample code, tips, and pointers so they can return home and get started building voice applications with open source and open standards.

If any of you will be attending, please do drop me a note as I always enjoy meeting up with people who read this blog. If you are not attending but are interested, it's not too late... you can still register at the OSCON site. Should be a great convention for those interested in open source development. The schedule is pretty amazing as it truly has a collection of some of the best folks out there in the open source world. (The convention starts on Wednesday with Monday and Tuesday being for tutorials.) I'm definitely looking forward to the event!

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

As 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.

Voice mashups - Notes on Alec's conference call today

UPDATE, Jan 11: The recording of this conference call is now available.

---

As I mentioned in an earlier post today, Alec Saunders convened a 30-minute conference call today on voice mashups. The call was recorded and will be available as a podcast from his site. (I'll add the link here once I'm online.)

I was traveling down through the state of Vermont today and so while I had no Internet access I did call in and joined the call from my Blackberry. (My wife was driving the car at the time.) I wrote down the following notes on my laptop during the call.

---

Alec introduced the call, mentioned that it would be recorded and distributed as a podcast. He then muted all the callers except for himself, Thomas Howe, Jim Courtney and Andy Abramson. For callers with Facebook open, they could press a button to "raise their hand" at which point Alec could unmute them. I was calling in on my cell phone while traveling with no Internet access, so for me it was to press "*2" to raise my hand.

Alec tossed out the first question which was "what is a voice mashup?" Thomas laid out one definition which Andy then amplified. Alec then asked if a mashup could involve something like Skype to which Jim described the results of the Skype Mashup contest and the winning PamFax app. Alec asked for examples and Thomas gave several. Alec asked how this looked like to the end-user. Thomas mentioned that it could be a web interface, but it might also simply be a telephone interface. The user would just call a number and do some kind of service. (Thanks for the mention of Voxeo, Thomas!)

Alec asked next "why do people build these?" Thomas... they are lightweight, easy to put together, easy to build for small interest groups (and therefore easy to put together a business case). Most ubiquitous interface is the phone. Business case can be small, but because of the architecture the application can actually scale massively if necessary. Jim... talked about ROI of PamFax... ability to take business documents from one location to another. Andy... mashup apps need to serve a purpose. Small, focused apps will be the general rule. However, that can be repurposed. You can globally deliver an app to small pockets of people who need that application. Andy recommends you look at Salesforce.com's app exchange. Mentions Mashery and the work they are doing looking into how you manage the rights around the use of mashup apps.

Alec - "So how do you monetize mashups?" Thomas... at least 3 hooks for monetization: 1) make businesses run faster, eliminate delays; 2) customer satisfaction - giving users a view into your system without; 3) make businesses more efficient. Question from (Dean - someone on wall) - who is making the money? Thomas - most of the work is in professional services. Focus is on developing apps, not necessarily in sale of apps.

(At this point I pressed *2 to raise my hand to ask a question related to monetization. A few minutes later I pressed *2 again.)

Tony from Voxalot talked about his voice mashup for an Australian dating site that allows users to be anonymous callers. Jim Courtney mentioned that PamFax is getting revenue on every transaction. Tony, I believe, also mentioned that Alec is getting revenue based on the usage of his conference call app.

Thomas... mashup architectures allow you to not have to pay upfront capital costs. You don't have to pay for a phone number and manage it, for instance. You can just temporarily use a phone number. Mashup architectures lower the barriers to entry.

As it was now 10:00am, Alec suggested that we should wrap up the call and throw it out to the assembled crowd for questions. It sounded from the tone of his voice that he wasn't seeing anyone raising their hand (and I was wondering what happened to my *2!). Thomas started answering...

---

... and then I entered one of those glorious pockets of Vermont where Verizon has no cell phone coverage - and so I was dropped off the call. Since it sounded like it was going to be wrapping up, I didn't bother calling back in a few minutes later when I was back in a coverage area.

All in all it was an interesting discussion. It undoubtedly could have gone on much longer. As I've been wanting to write more about this whole topic of voice mashups, I'll probably have some further posts on this soon.

It was also an interesting usage of Alec's Facebook "Free Conference Calling" application. The Iotum gang has certainly developed that app further and I'll definitely be looking at it again and toying with some ideas about how to use it. The recording feature is certainly an interesting one for someone who likes producing podcasts... :-) (Although it does not seem to be wideband so you are still limited to lousy PSTN audio.)

It's the (app) platform, stupid!

"Phone systems" are dead. PBXs are dead. IP-PBXs are dead.

Well, okay, not really... people will still be buying "PBXs" for quite some time. Just as there are certain communities out there who still buy horse-drawn wagons. But the reality is this:

"Phone systems", PBXs and IP-PBXs without easy application programming interfaces (APIs) are a dead branch on the evolutionary tree.

The future of communication belongs to mashups. To quick and easy ways to interconnect disparate systems. To integration of communication systems with business processes and other applications. In a world where voice is no longer always the primary mode of communication, we have to stop thinking about "phone systems" and take a larger look at how "communication" in general fits into our infrastructure. More than just how we use the system, we have to look at how we can get data in and out of the communication system. To borrow from the 1992 Clinton campaign:

It's the platform, stupid!

As you look at communication choices, the question is really about who has the "best" APIs... whose system is easiest to integrate with.... who lets you get data out of their system easily - and also lets the data back in... who lets you control the communication experience through an external application (and does so securely, naturally).

There's a good number of players out there who "get it", and either have or are in the process of developing a strong ecosystem of application partners, but let's take a quick spin down the list of some of them:

• Microsoft - Duh! Everything about Office Communication Server and all the other components is all a platform play. The goal is integration of communication into the rest of your IT infrastructure (which they would of course like to have you run entirely on Microsoft products).
• IBM - They don't usually get as much mention as Microsoft, but IBM's been back there making Sametime a communication platform play similar to OCS (only it has been out there for several years). With their latest move to OEM components from Siemens to make their Universal Telephony Server to allow interconnection with many different IP-PBXs, they very clearly see the value in integration.
• Digium/Asterisk - The name Asterisk also refers to the "*" wildcard character which in UNIX-land basically means it will match on everything. Asterisk has always been about being a platform for telephony/communication from its very beginnings.
• Skype - With its "Extras" gallery and the developer program they have been working to promote, Skype is trying to be an applications platform and currently does have many applications now available (use the "Do More" link to get to the Extras Gallery).
• Oracle - They don't get as much coverage, but I would watch what the folks at Oracle are doing, because they are building communication solutions that move around Oracle's database solutions.
• Social networking sites - Facebook and MySpace don't immediately come to mind as "communication" choices, but the reality is that they are becoming that - and they both understand the need and value in an API ecosystem. How well they will execute remains to the be seen.
• The IP-PBX vendors... to a degree - I hesitate on this one a bit. Some of the vendors get this. Avaya has been running around with their SOA toolkit. Siemens has been doing a good bit of work in this space (so much so that IBM OEM'd product from them). Cisco has been running around buying up companies. But at least to me it seems to be somewhat half-hearted. For the others I've listed, communication is a platform, while for the vendors it seems to be something else they need to do. It's a different mindset which, I think, reflects the IT focus of the ones I've listed previously.

There are certainly others out there ... and more will undoubtedly enter the space in the time ahead. The key question I think we all in general need to be asking:

How well does your communication system provide a platform for applications? (or for integration with applications?)

P.S. And yes, my new employer is one of those who understands this... although ironically I wrote the draft of this entry about 3 weeks ago before I'd even heard of them... but more on that later today. :-)

Digium buys SwitchVox and gets presence, Web 2.0 interface, mashups to Google Maps, Salesforce.com, SugarCRM...

Imagine you are a customer service rep (CSR) at a small/medium company and a phone call comes in from a customer. As your phone rings, up on your screen pops all the information about that customer, pulled from your CRM database in Salesforce.com or SugarCRM, plus other information from other databases and finally a nice Google Map showing you where that customer is located and potentially other information like the locations of your nearest offices. During the call, the CSR needs to bring in a subject matter expert so the CSR consults their web panel and looks at the presence information displayed for each of the other people in the business. The CSR can then contact someone showing as available and potentially bring them into the call.

Now imagine that all that is running on top of open source telephony... specifically Asterisk.

You can now stop imagining, because Digium just bought the company that does precisely that. There will undoubtedly be much attention today (at the very least in the VoIP blogosphere) about Digium's announcement here at AstriCon today that they have acquired SwitchVox. I am going to bet that much of the reporting today will focus on angles like these:

• Digium now has very competitive offerings (SwitchVox SOHO and SwitchVox SMB) for going after the small / medium business market.
• Digium bought themselves a very sophisticated/simple/easy GUI/management interface that moves them forward dramatically in making Asterisk easy to use, deploy and manage.
• Digium just got 1400 paying customers with over 65,000 endpoints.
• Digium bought themselves parity (or more) in their ongoing competitive feud with the folks at Fonality/Trixbox.

All of that is true. The SwitchVox products offer a very seriously competitive list of features (you have to go through and expand the subsections to see all the features). The GUI is very well done and simple. The price is quite compelling for the servers and also the support. I mean, for $1200 ($995 server plus $199 support) an SMB gets an IP-PBX with a very broad range of features and an unlimited number of users! Yes, the business still has to pay for IP phones, but they can buy any of a wide range of phones at varying price points to suit their needs. Considering that almost all the mainstream IP-PBX vendors charge on a per-user basis for licenses, the unlimited user model is certainly disruptive in its own right. (Digium has also been doing this with their Asterisk Business Edition.) And yes, Digium now has an answer to the growing competitive threat of Trixbox and it's management interfaces, support, hybrid model, etc.

All that is true - but it's not the really interesting story.

To me, what is far more compelling is that Digium just bought themselves a whole group of people who "get" the world of "unified communications", business process integration, Web 2.0 mashups, etc.

Digium has had no story at all around "presence" within its core offerings. Now it does. While Asterisk has always been a platform play where you have the ability to integrate Asterisk with other apps, doing so has not exactly been for the faint-of-heart. Hire yourself some programmers and you can do pretty much anything with Asterisk... but that's not something that many businesses want to get into. SwitchVox now gives Digium a way to do easy integration with databases and web sites. The integrations to Salesforce.com and SugarCRM are slick. The Google Maps popup is a seriously cool mashup! (And where is that on the roadmap of the mainstream vendors?)

Throw in a "click to call" add-in for Firefox to let you dial any number you see on any web page, plus a plug-in for Outlook, and you've got a very compelling offering. For a very nice price. My only knock (other than the fact that I can't find a picture of their Google Maps mashup anywhere on their website) is that it doesn't seem like their presence capability is yet integrated with existing instant messaging services. Given Asterisk's XMPP (Jabber) capabilities, this seems an obvious path that could get them connected to Jabber and GoogleTalk presence information. If they don't have that yet, I hope they add it soon, as we really do NOT need yet another place to change/update our presence info.

Regardless, this integration capability is, to me, the real story. Phones are being commoditized. I have to believe call servers/IP-PBXs are on their way to being commoditized. (Folks like Microsoft are going to help in pushing those prices down.) The money will ultimately go away from those areas.

The future of "unified communications" is about platforms. About mashups. About web services. About exposing APIs. About making it easy to combine different sources of data into interfaces that make people more productive. Microsoft gets that. Some of the traditional IP-PBX vendors get that. Digium has always known that, but this acquisition gives them a far better ability to make it happen.

Congrats to the folks at both Digium and SwitchVox for making this happen... I very much look forward to seeing where it evolves! (And in the meantime, I'm going to have to go down to the AstriCon exhibit hall and get some video of the Google Maps mashup to show how very cool it is...)

Skype Mashup Contest: And the European winner is......

The first result of the Skype Mashup contest was announced yesterday at the Skype developer event in Prague, and the winner is....

PamFax!

Yes... a fax application!  As Jim Courtney writes over on Skype Journal (he was also one of the judges):

The PamConsult team created PamFax to solve the problem of providing a very simple process (especially relative to the somewhat cumbersome WinFax) of using the Internet to easily fax an MS Office document anywhere worldwide. The primary Skype feature here has nothing to do with voice; they used the Skype Extras publishing platform not only to install the application but also as a transaction processor for collecting revenues for the service using Skype credits. Skype Chat is used to send notifications re a fax's delivery. In addition they developed a web-based portal to manage and archive your use of the service. The application can be launched from the Skype Extras menu or from within MS Excel or MS Word. A link to Google Maps will also show roughly where the fax is being sent (to within an Area Code).

The interesting aspect to me is how it uses Skype's micro-payment infrastructure.  No need for credit cards or anything... it just debits your Skype Credit.  Your Skype Credit, in turn, can be linked to your PayPal account... which can then pull money from credit cards or bank accounts.  So you wind up with a very effective and simple way to bill people for services rendered.

Jim goes on to explain a bit more about what PamConsult did:

PamConsult married the Google Maps API's, Microsoft Office COM objects and a backend fax API with their long term experience using the Skype API's. They started a year ago this summer with development of specifications; coding commenced in January with an initial version available in May. After a beta testing program in July, PamFax was released as a Skype Extra in the second week of August.

As noted in the Skype Developer blog post, winners in the US and Japan will be announced at those specific events over the next couple of weeks.  

The list of submitted mashups can be found in the Skype Extras gallery.  Some look quite intriguing and I'll perhaps write more about them in the future.

Skype Journal: "The Dawn of the Mashup World"

For a couple of months now, a post has been swirling around in my brain that I was tentatively titling "The Dawn of the Mashup Culture" in which I wanted to talk about "mashups" and why they are so incredibly important.  Unfortunately I just haven't had the time to put all those thoughts into the written word.

Well, in the meantime, Jim Courtney went off and wrote something very close to what I was intending to do:  "The Dawn of the Mashup World - Part 1: Challenges, Why and Expectations"  followed by "Part 1a: What is a Mashup?"

Read them.  (And the follow-on posts that Jim indicates he's writing.)

Mashups are fundamentally changing the way we can use and control services.  It's the remix culture. 

You need to understand it... because if you don't, your products and services will be left behind.

Open APIs win.  Mashups win.
