Description

G711Sid RTP Payload Type

Specifies the G.711 Silence Insertion Descriptor (SID) RTP payload type, in the range of 0 to 127. This applies only if preferred audio encoding is G.711 with Silence Suppression.
The default value is 19, which is Sonus-proprietary comfort noise.
The other possible value is 13, which is standard RFC 3389 comfort noise.

Heartbeat

• enabled—send SID packets during silence intervals to provide an estimate of the background noise to the receiving end.
• disabled (default)—Do not send SID packets, placing the burden on the remote side to determine the way it will generate comfort noise.
