peer device. -1 is the quietest, and 1 is the loudest.

the peer device. -1 is the quietest, and 1 is the loudest.

Echo Cancellation

G.168 Active Select this if you want to eliminate the echo caused by the sound of your voice

reverberating in the telephone receiver while you talk.

Fax Option This field controls how the ZyXEL Device handles fax messages.

G.711 Fax

Passthrough

Select this if the ZyXEL Device should use G.711 to send fax messages. The peer

devices must also use G.711.

T.38 Fax Relay Select this if the ZyXEL Device should send fax messages as UDP or TCP/IP

packets through IP networks. This provides better quality, but it may have inter-

operability problems. The peer devices must also use T.38.

Dialing Interval

Select

Dialing Interval

Select

Enter the number of seconds the ZyXEL Device should wait after you stop dialing

numbers before it makes the phone call. The value depends on how quickly you

dial phone numbers.

If you select Active Immediate Dial in VoIP > Phone > Common, you can press

the pound key (#) to tell the ZyXEL Device to make the phone call immediately,

regardless of this setting.

VAD Support Select this if the ZyXEL Device should stop transmitting when you are not

speaking. This reduces the bandwidth the ZyXEL Device uses.
