DTMF Relay for H.323
After the VoIP call is connected, when you dial a digit, this
digit is sent to the other side by DTMF tone. There are two
methods of sending the DTMF tone. The first is “in band”,
that is, sending the DTMF tone in the voice packet. The
other is “out band”, that is, sending the DTMF tone as a
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.

mode, enable this selection when it is necessary. The
default is disabled (using fast start mode).
