RE: VAD Bandwidth gain on G722 and G729

Voice Activity Detection (VAD) is used in speech processing to detect the presence or
absence of human speech. When detecting period of “silence”, VAD replaces that
silence efficiently with special packets that indicate silence is occurring. It can facilitate
speech processing, and deactivate some processes during non-speech section of an
audio session. VAD can avoid unnecessary coding or transmission of silence packets in
VoIP applications, saving on computation and network bandwidth.

For the present , no obvious disadvantage is found in turning it on
