I’ve noticed that when calling from my iPhone to another iPhone over ATT or TMobile, Wideband audio appears to be in-use. Does anyone know of any way to get end-to-end G722 or other high quality codec to work outside of our local switch?
Just about every major sip trunk provider just supports G.711
We are a national broadcaster and would love to be able to get higher quality calls without having to send each guest a SIP phone registered to our switch.
