Comfort Noise Generation
When using VAD, the VDSL Router 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.
MWI (Message Waiting Indication)
Enable Message Waiting Indication (MWI) enables your phone to give you a
message–waiting (beeping) dial tone when you have a voice message(s). Your
VoIP service provider must have a messaging system that sends message waiting
status SIP packets as defined in RFC 3842.
Custom Tones (IVR)
IVR (Interactive Voice Response) is a feature that allows you to use your
telephone to interact with the VDSL Router. The VDSL Router allows you to record
custom tones for the Early Media and Music On Hold functions. The same
recordings apply to both the caller ringing and on hold tones.
Recording Custom Tones
Use the following steps if you would like to create new tones or change your
tones:
1
Pick up the phone and press “****” on your phone’s keypad and wait for the
message that says you are in the configuration menu.
2
Press a number from 1101~1105 on your phone followed by the “#” key.
3
Play your desired music or voice recording into the receiver’s mouthpiece. Press
the “#” key.
