Disruptive Telephony

Given 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.

As 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.)

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.

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.)

If you are interested in "voice mashups", as I am, and are available today from 9:30 - 10:00am Eastern US time, you might be interested in joining a conference call hosted by Alec Saunders and several others. More information can be found over at Alec Saunders blog:

Talking about Voice Mashups: "Thursday morning a few of us will be doing a round table discussion on Voice Mashups using the iotum FREE Conference Call service. Andy Abramson, Tom Howe, Jim Courtney and myself will convene for 30 minutes to have a con-cast (Conference Call + PodCast).  If you're interested in the topic, please join us and contribute. "

I'm going to be traveling today, but if cell service works, I'll be joining in. Should be an interesting conversation.

The major product Dean Elwood has been working on now that he has moved to Truphone is the Facebook application that Truphone announced two days ago. Their blog provides a link to the Facebook application and, of course, in true Truphone style, offers us a video with cows:

I've not yet had a chance to do more with it than install it and play a bit with the configuration options:

but I'm very much looking forward to giving it a try. There are several interesting aspects to this app for me:

• It is an embedded softphone (Java-based). No extra software you need. Just click the button and you can call the person who has it on their Facebook profile. To my knowledge this is the first time we've seen this in a Facebook app.
• From the user side, you can link that button to any of the following:
  • Your Truphone number.
  • Any regular landline or mobile phones in the US or Canada.
  • A SIP address.
  • A Google Talk address.
• A GrandCentral phone number.
• The Facebook app uses the IAX protocol used primarily by Asterisk. This gets around all of the firewall/NAT traversal issues that plague SIP.

All of that makes for an interesting new app inside of Facebook. Now, there are already a number of "click-to-call" Facebook apps out there (some of which I've covered here) but in his announcement of moving to Truphone, Dean talks about what is different:

There are several click to call/callback/speak type applications already on Facebook. The differentiator here, and the interesting part about this application (and also the hardest part) is that we’ve embedded a JAVA based softphone right into the heart of Facebook. This makes the experience from a user point of view seamless with the Facebook environment. The user never leaves Facebook, they speak into Facebook. Additionally, the "call me" button for this application is not restricted to your own profile page - it functions as a Facebook attachment, which means it can be dropped onto a friends Wall, or added to a Facebook mail message or any other attachment-accepting application which exists on Facebook now or might do in the future.

So now Facebook users can put this "Call Me For Free" button in other locations within Facebook... and Facebook users can use this as a way to stay inside of Facebook but yet new mix in voice communication to people outside of Facebook. Now I can look up someone in Facebook and then simply click the call button to reach them by voice directly.

I look forward to experimenting with the application in the next week or two. Those of you who are Facebook users and want to try it out can simply install the application.

What do you think? Do you think people will use this app? Does voice have a role mixed into a social network like Facebook?

By way of my Facebook NewsFeed this morning, I learned that several friends had installed a new Facebook app called "VoxCall" (must be logged into the walled garden of Facebook to see the link). A quick Technorati search brought me to Alex Saunders' blog post on the subject which clued me in to the fact that this was from the folks at Voxalot, some of whom I'd met down at Fall VON in Boston.

[Side Rant: This also shows the inherent weakness and stupidity of Facebook's current implementation of "groups". The Voxalot folks had posted info about this app in both the news and wall of their Facebook group, but of course I would never see it unless I just randomly happened to go there. Had they sent a message to all group users, I would have seen it in my Facebook Inbox, but it would be nice if instead Facebook had some way to notify you that you had new info in the groups to which you subscribe.]

The VoxCall app is basically a "click-to-call" app that makes use of Facebook's directory. You simply click on the name of someone else who has the app installed and, like many click-to-call apps, you are called first and then the other party is called and the connection is made.

An interesting aspect is that VoxCall works with SIP URIs (addresses). When you install the app you have to enter your SIP URI at which point you then receive a call on that URI where you are asked to enter the PIN displayed on the screen:

It's actually a pretty nice way of authenticating the endpoint. Given that Voxeo's a VoIP application platform company, we naturally all have SIP URIs for our extensions (sip:[email protected] for me) so it was easy for me to sign up. Users of Gizmo would likewise have a SIP address, as would users of many other VoIP services. If you don't have a SIP URI, Voxalot has a suggested path to get one on their VoxCall FAQ. (One thing I don't completely understand is why you would need to do their step #2, Register for a VoxPremium account, if you already get a SIP URI from the Voice Service Provider you signed up with in step #1. But maybe the point is that some of those VSPs won't give you SIP URIs... ?)

Once registered, the process is quite simple. You have a "Call Friends" tab that is shown below (complete with some advertisement being blocked by the local proxy server that I run that blocks ads from typical ad-serving sites):

You simply click on the person's icon and the call process starts. First it calls you, then it calls the other party. No charges incurred by anyone outside of whatever inbound connection fees we would normally pay (in my case, none). I called Alec and so my page changed to show his picture and the fact that I was calling him:

Alec and I had a good chat with surprisingly good audio quality given the convoluted path our call was taking. I was on a Polycom IP phone connected across the Internet to Voxeo's SIP servers in Florida. The call went across some network cloud to Alec's TruPhone number (which has a SIP URI) which wound up ringing his mobile as he was driving along the 401 somewhere in southern Canada. Audio quality was quite good and didn't seem to have any real issues in the 5 or 10 minutes we chatted.

The VoxCall app also has an Echo Test number you can call to hear the latency and has some conference rooms that I have not yet tried.

Overall, it's an interesting app, although I guess my basic question is simply this: will I use it? As I wrote earlier, the phone is no longer as critical of a communication tool for many people, myself included. When I think of Facebook, I think of it as a place for email-ish communication. If I need to reach someone urgently, I have used Facebook as a place to get a phone number from in the past. Will I think to use to it place a call in the future? I don't know.

There are a couple of barriers to that, really. First, the app only works with people who have it installed. Second, to install it you need a SIP URI and the whole concept of SIP addresses is only really now starting to come to people's attention (outside the early adopter crowd). Third, initiating the call requires going into the VoxCall application page inside Facebook to click on the person's icon to call. It would be nice if it could be done simply from the list of friends that you have. (Having said that, it's actually easier to simply go into the app page than it is to search through Facebook's friend list and then go into their profile to then click on a link below their picture.)

The nice thing about the app, though is that it does use the Facebook directory. As Alec puts it:

Perhaps the biggest differentiator for Voxcall is simply that it hooks into a directory that a lot of people know and use.

As Facebook continues its climb in popularity and moves onward toward the goal of being your definitive "portal" to the Internet, this VoxCall app (and others like Alec's own Free Conference Call app) help connect in voice to the communications mix (for those who still want/need to use it).

In any event, kudos to Voxalot to bringing out another voice app on top of Facebook. It's good to see the platform being used for voice. As a advocate for SIP and open standards, I applaud apps that promote the use of all things SIP. Give it a try. What do you think of it? (Feel free to give me a call if you are a Facebook friend of mine.)

"It's about an open platform, stupid!" While I didn't include Google when I first wrote my post about how voice is really all about application platforms, I did note in the comments that I had intended to do so... and today's announcement really shows that they should be in anyone's list of telephony application platforms. As announced on the Google blog with "Where's my Gphone?", Google today announced the Open Handset Alliance and the associated set of forthcoming software called Android. The front page of the Open Handset Alliance provides a rather compelling (to me) statement:

What would it take to build a better mobile phone?

A commitment to openness, a shared vision for the future, and concrete plans to make the vision a reality.

Welcome to the Open Handset Alliance™, a group of more than 30 technology and mobile companies who have come together to accelerate innovation in mobile and offer consumers a richer, less expensive, and better mobile experience. Together we have developed Android™, the first complete, open, and free mobile platform.

We are committed to commercially deploy handsets and services using the Android Platform in the second half of 2008. An early look at the Android Software Development Kit (SDK) will be available on November 12th.

The list of partners in the Open Handset Alliance is quite interesting... handset manufacturers, semiconductor companies, software companies... but also cellular/mobile operators such as Sprint and T-Mobile as well as NTT DoCoMo and the giant China Telecom.

Also intriguing to note that eBay is listed as a partner. Would this be for eBay itself or could it perhaps be for Skype? Adding Skype into this mix could be interesting as well.

The Google blog page contains this text which gives some insight into Google's interest:

Android is the first truly open and comprehensive platform for mobile devices. It includes an operating system, user-interface and applications -- all of the software to run a mobile phone, but without the proprietary obstacles that have hindered mobile innovation. We have developed Android in cooperation with the Open Handset Alliance, which consists of more than 30 technology and mobile leaders including Motorola, Qualcomm, HTC and T-Mobile. Through deep partnerships with carriers, device manufacturers, developers, and others, we hope to enable an open ecosystem for the mobile world by creating a standard, open mobile software platform. We think the result will ultimately be a better and faster pace for innovation that will give mobile customers unforeseen applications and capabilities.

We see Android as an important part of our strategy of furthering Google's goal of providing access to information to users wherever they are. We recognize that many among the multitude of mobile users around the world do not and may never have an Android-based phone. Our goals must be independent of device or even platform. For this reason, Android will complement, but not replace, our longstanding mobile strategy of developing useful and compelling mobile services and driving adoption of these products through partnerships with handset manufacturers and mobile operators around the world.

In the end, Google wants a platform upon which they can offer their many services. With this plan, they are hoping to turn a zillion mobile phones into a platform which Google - and many others - can use.

Fascinating move... and one that is naturally getting a ton of coverage in the blogosphere. I've not had the time to read much of it, but did catch Scoble, the NY Times article and ZDNet's take. I'm sure we'll all be reading much more about it in the days ahead.

Right now, all we can really do is speculate until next Monday when the (apparently open source) SDK becomes available. We shall see... although the initial signs are certainly that this could indeed cause some disruption.

P.S. One of the commenters on Scoble's blog wondered why there wasn't equivalent attention being given to http://www.openmoko.com/ , especially since it is out already with a product. My quick reaction would be that from what I know of OpenMoko, it is about an open platform, but from a single vendor and on a single hardware platform. This Google announcement would appear to transcend both the vendors and the hardware platforms. It's also an announcement from Google and it has impressive backers.
