H.323 VoIP Advance Configurtion
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.
