12.2.2 Comfort Noise Generation
When using VAD, the V500 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.
12.2.3 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.

12.4 Speed Dial Settings Screen
Speed dial provides shortcuts for dialing frequently used phone numbers. You can map a
phone number to an alphanumeric keypad key (1 to 9) and then use that keypad key to call the
phone number (press and hold the key for one second or longer). Use this screen to add, edit,
or remove speed-dial numbers for outgoing calls.
You also have to create speed-dial entries if you want to make peer-to-peer calls or call SIP
numbers that use letters.
