Now that I’ve got Opus running with FreePBX, I’m trying to find affordable physical phones that support Opus. What brands & models support the Opus codec?
So far, I know of:
OBi1000 Series (OBi1022, OBi1032, OBi1062)
Yealink SIP-T40P/T23P/T23G/T21§ E2/T19§ E2
I read that all the Grandstream models have it available via a firmware update? Is that true?
