Inter-Carrier HD Voice Updates?
I haven?t really heard anything on this subject in what seems like awhile so I figured I?d ask. Has T-Mobile been working on getting Inter-carrier HD calls with AT&T and Verizon users? It seems like Sprint might have VoLTE up and running before T-Mobile implements this. I mean they downgraded their voice codec for standard VoLTE (23.85 to 12.65 Kbps IIRC) for interoperability with the duopoly. AT&T and Verizon callers can call each other with HD voice, what?s holding back T-Mobile? Have they done their part?
Also posted this on Reddit but I figured the more knowledge the better.
