Features
Note: Call forwarding works only for calls that arrive over VoIP.
The X5v cannot forward calls from the PSTN. However, if you
have VoIP to PSTN service, you can forward VoIP calls from the
X5v to the PSTN.
The command sequence to control call management is simple. We
have included a sample table below. On your telephone keypad,
enter
# <Forward code> <Forward Number> #
The X5v will attempt to place a call to the Forward Number.
If someone answers within 15 seconds, the forwarding feature will
become active. If not, you need to re-enter the command:
# <Forward code> <Forward Number> #
Then the forwarding feature you have selected will become active.
You will hear a stutter dial tone while call forwarding is active.
Chapter 2: Voice Over IP Settings
Meaning
Enabled by default.
Call waiting signals you with a tone when
another caller tries to contact you while you
are on the phone. Press the hook button on
your phone to be connected to the second
caller, and the person you were talking with
will be placed on hold. Press it again to
return to the first conversation. If you
disable it, callers will either hear a busy
signal or they will be given the option to
leave a voice mail message; this depends
on your service provider.
Enabled by default. Dial the call return
number for your region, preceded by the #
sign, if you want the X5v to dial the last
number that attempted to call you. if you do
not know the call return number or it does
not work, dial # and then * 6 9
