Configuring SIP DTMF Relay
This section describes how to set the method of delivering DTMF tone via SIP
signaling. To relay DTMF tone, Ubigate iBG2016 supports the 4 methods as
follows.
inband
rtp-nte
sip-notify
sip-info
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 sip-
notify method delivers DTMF tone using SIP NOTIFY method. The sip-info
method delivers DTMF tone using SIP INFO method.
SIP NOTIFY based out-of-band DTMF relay format is simular to DTMF
message format described in RFC2833.
