1815-01: DTMF Relay
DTMF Relay allows a VoIP extension user to dial DTMF digits to control a remote voice mail or other
interactive service. If enabled for the selected profile, user-dialed digits are included as port of the
transmitted voice packet, separated out at the far end, and then sent to the destination as in-band DTMF
digits. If disabled, DTMF digits are not passed to the far end.
