Editorial: Snapshots of HD voice progress this month at TMCnet

I have  pair of articles on TMC discussing the latest progress of HD voice in the United States and around the globe.

For the U.S.–

HD voice has finally arrived on all four major U.S. wireless carriers. However, users should be aware of the different issues and potential problems with some carriers. 

Verizon launched Voice over LTE (VoLTE) last week, but only supports four phones and lost support for name and company name Caller ID info in the process (Not what I’d call Advanced Calling 1.0; more like Advanced Calling 0.9 when you LOSE features associated with analog calling).  You’ll also drop calls when moving between VoLTE and CDMA networks (Advanced Calling 0.8, maybe?)

Worldwide, HD voice is available on 116 mobile operators in 75 countries.

The kickers here are 3G HSPA operators playing catch up with the rest of the world and the forthcoming wave of VoLTE deployments that will roll out between the end of the year and the end of 2015.

As always, HD voice interoperability (i.e., being able to make seamless end-to-end HD voice calls across/regardless of network) looms large as the next big step for the mobile world. The SBC guys are going to have a field day over the next three years.
