[VoiceOps] HD / G722

My apologies, Apparently I'm a bit green on the process.
 From what I recall from past conversations on this list, A few carriers 
(Inteliquent being the one that stands out in my memory) would negotiate 
G722 if it worked for all parties. I think I even recall a number (Not a 
URI) being provided at that time with someone saying "This number will 
accept G722 on the Inteliquent network".
 I'm not actually the one doing any interconnecting here. I'm purchasing 
wholesale SIP. But I'm told, If I send a call in G722, They'll send out 
whatever I send. So, for S&G's, I was hoping to find someone else perhaps 
on any particular network known to support 722 that had a number to make a 
few test calls with. Since my carrier has interconnects with many networks, 
It's possible it would work to many of those networks?
 I've used the zipdx demo (Thanks mgraves). But I know my switch supports 
722, And that I can make direct IP calls to zipdx in 722.
 Thanks for the info!

In the US, you'll only get G.722 over which non-TDM PSTN networks.    
 So this question might be asked, "Is there a number that answers G.722 on 
Level(3)'s network?" or, "On Bandwidth's network?".  For Level(3), there 
used to be many, but at last testing, Level(3) had clamped down their codec 
list to G.711 only. I'd be glad if someone has newer news.
 This is just a hunch though: If you peer with the wireless carriers, 
directly to their SBCs with interconnection agreements with appropriate 
minimums, and it's to their advantage to peer to provide HD Voice, you can 
expect to exchange AMR-WB traffic to their VoLTE customers.

    Anyone have a test number that will answer in G722? Looking to do some 
HD testing.
 Furthermore, Anyone have any success sending an HD call to any of the 
wireless guys? VZW/ATT/TMO all seem to support AMR-WB (G722.2) at least on 
the UE to IMS side. Surely they won't transcode for me 722>722.2?
