Configuring The Advanced Analog Phone Screen - ZyXEL Communications P-2612HW-F1 User Manual

Voice Activity Detection/Silence Suppression
Voice Activity Detection (VAD) detects whether or not speech is present. This lets
the ZyXEL Device reduce the bandwidth that a call uses by not transmitting "silent
packets" when you are not speaking.
Comfort Noise Generation
When using VAD, the ZyXEL Device 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.
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.
