DTMF Method for SIP
After the VoIP call is connected, when you dial a digit, this digit is
sent to the other side by DTMF tone. There are three methods of
sending the DTMF tone. The first one is “in band”, that is, sending
the DTMF tone in the voice packet. The second one is
“RFC2833”, that is, sending the DTMF tone as a RTP payload
signal. The third one is “SIP Info”, that is, sending the DTMF tone
as a SIP signal. Sending DTMF tone as a signal could tolerate
more packet loss caused by the network. If this selection is
enabled, the DTMF tone will be sent as a signal.
