Moving from PSTN-based system to an all-IP world with SIP interconnections allows for seamless end-to-end HD voice calling, video calling and other powerful business and consumer applications - and that's why so many service providers want to make the switch.
But because it's still early for higher-level SIP interoperability, there are a lot of questions as to what service options are actually available.
Complicating matters in the HD voice world are numerous speech codecs and the necessity to translate between PSTN-grade service, G.722 for HD voice in the broadband and enterprise worlds, AMR-WB for mobile HD voice services in Europe, and the independence of Skype's (News - Alert) SILK codec just to make life even more interesting.
To set things straight, register for the April 14 Webinar "Interconnecting HD Voice and Video: Options Galore" at 2 p.m. EST. Hosted by Dialogic (News - Alert) and TMCnet, the webinar will educate attendees on available service options for HD voice interconnectivity.
Attendees will also get information on popular HD voice codecs and their applications., and learn how to transcode between different HD voice codec "islands."
Martyn Davies, director of technology, Dialogic, and Doug Mohney, editor-in-chief, HD Voice News, DougonIPComm, lead the session, the second of a two-part series.
