Doug on IP Comm – An independent voice on VoIP, telecom, and IP Communication

You’ll find three (3) pieces about HD voice from AstriCon over at the HD Connect Now website (–

Bottom line: You have to look REALLY hard to find a VoIP handset that doesn’t have support for the G.722 wideband codec these days.  Even Cisco’s $130 cheap-end VoIP phone has G.722 built in… and yes, I’m sure people are going to start nit-picking about mic quality, speaker quality, does the gear really sample at 16 KHz, etc… we’ll see.

Also very interesting that AT&T is quietly trialing HD voice in its back yard. No details yet on exactly what is going on; I’m hoping the company will be as forthcoming as Verizon Business, but then again, AT&T never rolled out Casabi after playing with it nearly a decade ago..


Dialogic and Digium have recently launched online communities to stimulate applications development for their respective products.   Digium is providing code, while Dialogic is offering prizes for new apps.

The Dialogic Exchange Network (DEN) and the Dialogic Innovator Award [Yours truly as one of the award judges] were launched in late April.  DEN is an online social networking community for customers, developers, Dialogic employees and others to connect, share ideas, learn about industry trends, and do the whole forum thing.

If you get a good idea from DEN for developing a new application, the Dialogic Innovator Award Contest awaits.  The most innovative application built using Dialogic components gets a free one-year service and support contact, $5000 credit to a future purchase of Dialogic products, t-shirts, press releases, and a joint marketing opportunity with the company.

Over at Digium, Switchvox Developer Central was launched last week. The website provides a wiki containing documentation for the Switchvox Extend API, a forum for discussions, a blog for the Digium engineering team, and tools for development and testing.

The big deal out of this is the exposure of the Switchvox Extend API. Third-party developers (i.e. either the do-it-yourself admin or a VAR/system integrator) can now go integrate their phone system with a custom web app.  It opens up a world of Switchvox-tailored vertical applications and ad hoc mashups.
