Disruptive Telephony

(Originally posted at http://dyork.livejournal.com/250011.html)

Publicity helps, of course. Start talking about something and the people start signing up. Overnight the VOIPSA "best practices" mailing list has grown from 26 to 65 subscribers, with more subscription notices coming in each time I look at my email. This certainly reflects the way I distributed the word... I'm sure many people, myself included, route the VOIPSEC mailing list into a folder where they read it when they can. Or at least they read other messages before that of a "mailing list". So I expect I'll continue to see subscriptions coming in over the next couple of days.

As the mailing list administrator, I naturally receive the subscription notifications and I have to say that there are some pretty impressive people and companies among those who have subscribed. I think we now have one or more representatives of basically all of the major IP-PBX vendors, a good number of security vendors, univerisites, US government agencies, a few financial institutions (good to have, given the natural security paranoia of banks)... plus a whole host of people that are using various Gmail, Yahoomail, etc. addresses that give nothing away about their identity. (I would expect nothing less from a group of security professionals! :-) Good number of folks participating from companies around the world. Knowing the caliber of some of the people who have signed up thus far, I'll admit that it could be a bit intimidating.... luckily, for better or worse, I've never been accused of a lack of self-confidence. :-)

A lack of time is a different issue, though, but it looks like things are okay to the point where I can spend the afternoon putting the last pieces together in the wiki to be able to start a discussion tomorrow. We'll see...

Progressive Grocer doesn't immediately leap to my mind as a place that would be writing about VoIP, but here they were writing about Peru's Number 2 supermarket chain deploying VoIP. On second thought, though, it makes sense that "progressive" food retailers would look at VoIP as a way to enhance/improve their operations. In any event, kudos to Mitel's partner in Peru, Data Voice, as well as our South American team, for winning the business. Our press release has more information (obviously from a Mitel perspective).

Over on "Voice of VOIPSA", Dustin Trammel wrote a long post called "Click-to-Harrass" that discusses "click-to-call" services and specifically the new Google Maps click to call capability. I wrote a comment that inadvertantly wound up being almost as long as Dustin's article. Given that it had been a topic I was thinking about writing about here anyway, I decided to cross-post my comment here as well.

Dustin,

Nice piece. TechCrunch also had a post yesterday speculating that Google had pulled Click-To-Call because of harrassment issues, although it seems to have just been a temporary service outage as the service is back running today (used it myself this morning).

The interesting thing, though, is that you can see the immense value to the consumer for this type of service. Over the past few days I've been testing it myself with calling various local businesses here in Vermont. I have to say it has worked great. Find them in Google Maps, click the "call" button, wait for the ring of my phone, press the "Talk" button on my wireless handset and... ta da... I'm connecting to the business. It is a little strange for other people in the house (i.e. my wife) to hear the phone ring once before I pick up, but outside of that, it works fine. From a consumer point of view, it's a wonderfully easy way to find businesses and connect. Why should I remember my dentist's number when I can just find them in Google Maps and click "call"? Simple. Easy. Convenient.

Interestingly, the Caller ID that I see is that of the business I am calling, so I'm not entirely sure how that is all working. You are right, though, that this does raise serious issues around the accuracy of call records. I'll have to look at my next phone statement and see how (or if) these calls are recorded.

From a security point-of-view, too, it's not entirely clear to me personally where all these calls are going. Presumably Google is using some VoIP Service Provider (some posts have indicated it is VoIP, Inc., in Florida) who is initiating the calls to myself and the other business. How long is my call actually in "VoIP" versus the traditional PSTN? What IP networks does it traverse? What is the window of exposure for interruption or interception? All good questions without ready answers (at least that I can see).

What is interesting to consider, also, is how fundamentally disruptive this and other similar services are to the traditional carrier market. Why should I pay Verizon (my carrier here in VT) anything beyond the very, very basic service if I can use these services for my connections? Given that the model today here in the US is that incoming calls are free, what is my incentive to go beyond the very basic plan? Suddenly instead of paying $50 or $70/month for an unlimited NA calling plan, I'm paying $15/month for rudimentary service. Just use a click-to-call service... especially a free one from Google, and you're set. Now, granted, I need to use some other service for calling residences, since Google is only businesses, but still, the point is that these services have to be giving carrier execs severe cases of agita.

It will also be curious to see the effect this Google effort has on JaJah and friends, where Google is making it free. Given that JaJah's business model seems to be around charging people for calls longer than 5 minutes, a move like this has got to be a threat to that model. On the other hand, they may be wagering on the "stickiness" of customers... once they have started using Jajah, they'll stick with it. However, customers are fickle and we've seen time and time again that free beats everything else (witness Skype's growth).

What I am not entirely clear on is the business model for Google. Obviously this service can drive people to use Google Maps, but okay... so what? As of this moment, there is no blatant advertising on any of the queries I've done. Now this may just be that no one has sponsored any links relevant to my very local queries. I note that when I did a query on "map store, boston, ma", I got sponsored links above and below my search results. So maybe that is it... which seems kind of weak to me personally. If I'm looking up a business, for me odds are pretty certain that I'm going to call that business. But maybe that's just me. Maybe enough other people are clicking on the sponsored links that giving away calling minutes is an effective loss leader to bring people to the site. I'm sure Google being the behemoth that they are they can get very aggressive pricing, so all the collective minutes may just be noise in their balance sheet.

Anyway, it's fascinating to watch all of these services evolve, and yes, as you indicate, there are serious security issues that do need to be addressed. We shall see how this all shakes out.

Thanks for writing this post,
Dan
