Hello, I am stuck while attempting to insert DTMF commands from a SIP gateway to an IVR menu running AGI php scrit. If I do: SIP phone --> ulaw --> IVR then dtmf works fine If I do: SIp gateway --> g729 --> IVR then the mneu still works but does not accept DTMF ? I have tried to set dmtfrelax=yes and dtmfmode=info, also tried dtmfinfo=rfc2833 Still did not work, any clues please?
