Configuring DTMF Relay
This section describes how to set the method of delivering DTMF tone via
H.323 signaling. To relay DTMF tone, H.323 gateway supports the 4 methods
as follows.
inband
rtp-nte
h245-alphanumeric
queued-digits
The inband method delivers DTMF to a voice path without separate
processing. In this case, a distortion may occur due to loss of RTP packets.
The rtp-nte method delivers DTMF tone via RTP according to RFC 2833, RTP
Payload for DTMF Digits, Telephony Tones and Telephony Signals. The
h245-alphanumeric method delivers DTMF tone via H.245
UserInputIndication message. The queued-digits method delivers DTMF tone
as RTP packets according to RFC 2833, and Queued Digits are supported for
analog-FXS subscribers.
