We  (ZipDX) have been interested in HDVoice interop with them for some time. We 
reached out to T-Mobile earlier this year, but it seems that they were not 
ready to HDVoice exchange traffic with anyone.
 
We also investigated smaller cellular-to-SIP gateway devices that supported 
AMR-WB, but could not find any available.
