Prestige 2602H/HW Series User’s Guide

9.6 Phone

You can configure the volume, echo cancellation and VAD settings for each individual phone port on the Prestige. You can also select which SIP account to use for making outgoing calls.

9.6.1 Voice Activity Detection/Silence Suppression

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

9.6.2 Comfort Noise Generation

When using VAD, the Prestige 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.

9.6.3 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.

9.7 Phone Configuration

Click Voice in the navigation panel and then Phone to display the following screen.
