11.3.1 Voice Activity Detection/Silence Suppression

Voice Activity Detection (VAD) detects whether or not speech is present. This lets
the V300 reduce the bandwidth that a call uses by not transmitting "silent
packets" when you are not speaking.

11.3.2 Comfort Noise Generation

When using VAD, the V300 generates comfort noise when the other party is not
speaking. The comfort noise lets you know that the line is still connected as total
silence could easily be mistaken for a lost connection.
