HDConnect discusses benchmarks for HD voice service

Washington D.C. — A group of HD Voice industry executives met yesterday to discuss the issues and hurdles facing the widespread and ubiquitous  proliferation of HD service around the globe, as well as potential ways the U.S. government could foster the uptake of wideband technology.

Discussions were lead by HDConnect Executive Chairman Dan Berninger with participants including Dave Erickson of WydeVoice, Mike Rude of DSP Group, Jim Machi of Dialogic, Jeff Rodman of Polycom, and Ari Rabban of Phone.com; Editor-in-Chief Doug Mohney also offered information and comment at times during the afternoon sessions.

How good is HD voice compared to a regular PSTN call? A consensus formed around the concept of using a “toll quality” PSTN call as a rating/yardstick/benchmark of 1 with HD voice providing at at least “twice the sound” of a regular call.

The marketing benchmark would enable a simple way to describe HD to consumers and policymakers, as well as allow vendors to rate/compare existing products/codecs to both “SD”/PSTN calls and to current and future technologies with the belief that companies would work to evolve HD beyond a simple “2 times” beyond PSTN through competition.

Interoperability/interconnection came up several times with no clear solution as to how to facilitate and encourage efforts by enterprise and service provider islands to interconnect for end-to-end HD voice calls.  One suggestion was to have the federal government mandate SIP interconnection as current phone call interconnection is mandated today.

Discussing what roles the federal government could play in the adoption of HD lead to a range of suggestions from having the administration’s COO and/or CTO make wideband voice a standard method of communications for agencies because of its ability to improve the effectiveness of voice calls and conference calls to having the FCC insert the use of HD voice as one of the clear-cut improvements the national phone system and/or national broadband plan should implement as it transitions from legacy technology to an all-IP network.
