[VoiceOps] HD Voice / Wideband audio?

[Michael Graves]

Just an aside - in the wireless realm they may actually be using EVS. One of the attributes with EVS is that it has modes that are AMR and AMR-WB compatible. Thus, I'm told that the wireless carriers don't need to transcode it at the edge. The phones themselves will switch modes when necessary, passing AMR-WB to the foreign network.

 Nope, becoming table stakes. I push opus everywhere I can these days. Smaller footprint, HD experience, packet loss concealment. The downside is its relatively processor expensive to transcode. 
 Most of the wireless guys are using AMR which is royalty bearing and not quite as advanced. 
 Look at it like this, change codecs because you want better experience in less network footprint, the HD part is a bonus.

  I know this topic has come up a few times on the list before but now I can't seem to find the discussion(s)  now.    Is it mostly the wireless carriers  that support HD Voice / Wideband audio?
