I have a test 3CX with 2 Cisco 7961G phones. No Gateways configured - just the 2 extensions. I can dial no problem, but the system doesn't recognize DTMF during calls. For example, the VM answers and waits for the pin, but doesn't 'hear' it. The template has the following DTMF settings: <dtmfAvtPayload>101</dtmfAvtPayload> <dtmfDbLevel>3</dtmfDbLevel> <dtmfOutofBand>avt</dtmfOutofBand> Any suggestions? Thanks!
