HD Voice / Wideband audio?
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?
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. -Ryan On 8/14/2018 2:33 PM, Ryan Finnesey wrote:

I?m 100% SIP in and out via Inteliquent/Neutral Tandem/Bandwidth.com. I run Broadworks which is codec agnostic and lets the end points figure it out. I enable all codecs supported by end points (Polycom). I?m seeing 15.6% of calls establish as g722, 1.5% as g729, 0.1% as g722.1, 0.5% t38 and the rest g711u -Matt -- Matthew Crocker Crocker Communications, Inc.

Matt, Are those G722 calls between users hosted on your switch (internal calls) or external calls from other Bandwidth.com carrier customers? On Wed, Aug 15, 2018 at 8:21 AM Matthew Crocker <matthew at corp.crocker.com> wrote:

Most of my traffic runs over Inteliquent and about 14% of that traffic is g722. I?m not seeing any g722 traffic through bandwidth.com or ThinQ -Matt -- Matthew Crocker Crocker Communications, Inc.

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.
