SIP INFO
DTMF digits are transmitted by the SIP INFO messages when the voice stream is established after a successful
SIP 200 OK-ACK message sequence. The SIP INFO message is sent along the signaling path of the call. The SIP
INFO message can transmit DTMF digits in three ways: DTMF, DTMF-Relay and Telephone-Event.
