VAD can avoid unnecessary coding or transmission of silence packets in VoIP applications, saving on computation and network bandwidth.
Comfort Noise Generation (CNG) is used to generate background noise for voice communications during periods of silence in a conversation.
Note: VAD is used to send CN packets when the phone detects a “silence” period; CNG is used to generate comfortable noise when the phone receives CN packets from the other side.
The following table lists the parameter you can use to configure VAD&CNG.
Parameter | DBID_VAD_CNG_MGT |
