I have a GS BT102 which when receiving calls that include DTMF tones only have short clipped beeps. Is asterisk not passing the DTMF info on to the phone or is the tone not bing generated by the phone? I am trying to check that I am getting the DTMF for an application where the length that a key is held down is important so need the SIP device to be sent the start and end of each key press the user makes.
