clarity Posted November 22, 2008 Report Share Posted November 22, 2008 Tested with Polycom Phones (IP-650) (IP-670) and IP330 If I change the top (preferred codec) to be G722 in PBXNSIP.. Either globally (settings) -or at the individual account.. G722 calls work great between supported phones and to PBXnsip IVR/Voicemail prompts. However all calls break to other phones that do not support G722 such as Polycom IP-330 or to the PSTN gateway which is G.711 This is not expected behavior. I'd expect if one leg of a call.. be it another phone that does not support G722 or the PSTN Gateway (G711 only) should cause both legs of the call to fall back to the common accepted codec (g711). This is not happening... the IP 650's and 670's are still showiing "HD" in the display and get NO audio with the other end of the call which is G711. G722 phones sem to 'have no clue' that the far end is not supporting G722. I can provide packet traces if needed.
