HD Voice

VoIP traffic has been growing exponentially in recent years, as both enterprises and consumers increase their adoption of IP services. To keep pace with the demand, fixed networks, mobile 4G networks, cable networks and enterprises are migrating to IP-based infrastructure. The true potential of IP-based voice communication has not been realized so far because of the narrowband voice technology in use today. HD voice promises to change the consumer experience with VoIP communication by offering clear, vibrant and life-like conversations. As the leader in VoIP communication for over a decade, Sonus is at the forefront of enabling HD voice communications in IP networks and enterprises.

 

While HD Voice offers significant benefits in terms of crisper, clearer conversations and better comprehension, its users can only communicate in HD with other people who are on the same HD network or who are using the same HD codec, such as 3G users with AMR-WB. This restriction creates "islands" of HD voice users, a fragmentation that prevents the technology from being adopted widely. By enabling transcoding between the important HD Voice codecs, Sonus creates a unified, seamless HD Voice service that allows any user to reach any other user on any network in crystal-clear HD.

Current Analysis
Joe McGarvey, Principal Analyst of IP Infrastructure
 
"Like many early technologies, HD Voice has been hampered by vendors using different codecs for their equipment without any transcoding support in the network.  This has kept most people from using the service, as it restricted who they could reach in HD.  It's bascially like buying an HDTV that can only get HD Video on a few channels.  As the industry works towards a standard HD Voice codec, Sonus' new HD Voice transcoding, combined with the company's installed base, takes the technology a giant step forward".
