Before You Begin; The Sip Service Provider Screen - ZyXEL Communications P-2612HNU-F1 User Manual

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.
Use this screen to maintain basic information about each SIP account. You can
also enable and disable each SIP account, configure the volume, echo cancellation
and VAD (Voice Activity Detection) settings for each individual phone port on the
ZyXEL Device.
