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.

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.
