XConnect (www.xconnect.net) is touting an AudioCodes HD voice transcoding solution between wireline and wireless networks for its HD Alliance customers. The Alliance is an IP-based federation with 11 service providers.
The new capability uses XConnect’s carrier-ENUM registry and IP interconnection services along with AudioCodes’ Mediant 3000 transcoding solution. XConnect says the solution has been “tested” and “certified” from end-to-end.
As a part of the deal, AudioCodes will also become an HD alliance partner and support cooperation and marketing efforts between the companies. Last year, XConnect did a marketing deal with Broadsoft, Dialogic, and Polycom to promote HD voice technology in the UK.
A review of the HD Alliance members currently lists 9 small to mid-sized service providers, plus two conferencing providers. All of them currently deliver HD voice in G.722; there are no AMR-WB wireless carriers listed in the HD alliance at this time.
XConnect may be the first to formally announce G.722/AMR-WB transcoding, but Tier 1 carriers are also designing transcoding solutions. Earlier this year, France Telecom said it would be enabling HD voice interoperability transcoding between its G.722 wireline and AMR-WB wireless networks in the 2012/2013 timeframe within countries and between its networks. Last year, AT&T hinted that transcoding between G.722 and AMR-WB would be a part of its SIP peering/transit network. Finally, Verizon is likely working on a solution between its G.722 Viper network and the LTE AMR-WB solution to be turned up next year.
