Vodia PBX Posted January 15, 2009 Report Share Posted January 15, 2009 ever since we upgraded to versino.3120 any grandstreams phone in our enviornment are unable to send dtmf in voicemail menu...DTMF works when calling other phone numbers. There is probably a problem with the DTMF codec negotiation. Try the latest Grandstream firmware or try setting the codec on the phone to 101, that's the codec the PBX will propose.
