Configuring call forwarding via VoIP

vider-dependent). You can activate/deactivate call forwarding via the Web configurator.
You can also make settings.
¤ Open the Settings ¢ Telephony ¢ Advanced Settings website in the Web configurator.

If you activate Yes, the two external parties you are toggling between will be connected
when you press the end call key a. Your connections with the callers will be termi-
nated.

networks).
Original URL
This protocol is recommended when the base station is connected to the Internet via a
router with NAT.
Automatic Refer To
If you activate Yes, the base station will attempt to determine the best protocol automat-
ically.
If the base station cannot determine the best protocol, it will use the protocol defined
in Preferred Refer To.
¤ Now click Set to save your settings.
