SIP VoIP Advance Configurtion

DTMF Relay 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.

RFC2833 Payload

Adjust RFC2833 DTMF payload value; range from 96 to 127, default is

101.

Watchdog

Silence Compression

(VAD)

If this function is enabled, when silence is occurred for a period of time,

no data will be sent across the network during this period in order to

save bandwidth. (If you use Asterisk, please disable Silence

Compression, it maybe make you call disconnect.)
