10.6.2 Comfort Noise Generation
When using VAD, the Prestige generates and sends comfort noise when you are not speaking.
Comfort noise uses the lowest possible transmission bandwidth to match the background
noise. The comfort noise lets the person at the other end of the connection know that the line is
still connected (total silence would easily be mistaken for a lost connection).
10.6.3 Echo Cancellation
G.168 is an ITU-T standard for eliminating the echo caused by the sound of your voice
reverberating in the telephone receiver while you talk.
