WASHINGTON--(BUSINESS WIRE)--Voice Communication Exchange Committee (VCXC) launches the HDN Phase II Trial demonstrating HD voice provisioning through the Number Portability Administration Center (NPAC) operated by Neustar. The HDN provides a mechanism for provisioning HD voice between all US operators, who rely on the NPAC for seamless interoperability.
The expanding deployment of HD voice includes all major operators with AT&T, Verizon, T-Mobile, and Sprint making HD voice announcements in 2014. VCXC estimates the population of HD enabled IP phones includes 70 million devices, but there remains no interoperability supporting HD voice calling between any of the operators.
"HDN provides network operators a learn by doing opportunity and a means to explore novel IP transition enabled deployment models," said Daniel Berninger, founder, VCXC. "HDN users dialing '00' and the standard destination telephone number obtain the benefits of both a HD voice connection and Internet like unmetered calling between participating operators."
"Neustar included an IP field within the NPAC in anticipation of service creation opportunities like HD voice arriving with the IP transition," said Tom McGarry, Neustar Fellow. "Neustar supports the spirit of experimentation demonstrated by VCXC's HDN Phase II effort as an interesting test of HD voice as a use case for interoperability."
"Inteliquent welcomes the opportunity to support the VCXC HDN Phase II proof-of-concept by serving as the default media route between participating network operators," said Ian Neale, Sr VP Global Voice Services, Inteliquent. "HD voice represents an important and immediate benefit of the IP transition for the communicating public."
VCXC - Voice Communication Exchange Committee - launched an effort to complete the IP transition by 2018 at the IP Transition as Grand Challenge event in June 2012 and the case for industry interoperability via the Petition for a HD Voice Migration Notice of Inquiry in February 2014.
