Configuring call forwarding via VoIP
If you are toggling calls via VoIP connections, you can connect the two external callers (pro-
vider-dependent). You can configure settings for this type of call forwarding.
¤ Open the following Web page: Settings ¢ Telephony ¢ Advanced Settings.
¤ Configure the following settings in the Call Transfer area for call forwarding via VoIP:
Transfer Call by On-Hook
If you have activated Yes, the external parties you are toggling between will be con-
nected when you press the end call key a. Your connections with the parties will be
terminated.
To learn how to forward a call when you have activated No, please see page 42.
Preferred Refer To
Define the protocol (the contents of the "Refer To" information) that should be used with
preference when forwarding calls:
Target's contact info
This protocol is recommended for "closed" networks (internal company and business
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.
Setting Area Code Predialling
In VoIP calls you must generally always dial the area code – even for local calls.
You can save the need to dial the area code for local calls by activating the Area Code Predi-
alling function. In VoIP calls, the area code entered is then prefixed to all numbers that do
not start with 0 – even when dialling numbers from the directory and other lists. Excep-
tions: Numbers for which you have defined dialling plans (page 135). The area code is not
added as an area code to these numbers.
¤ Open the following Web page: Settings ¢ Telephony ¢ Dialling Plans.
Configure the following settings in the Area Code Predialling area:
¤ Enter your area code in the Area Code field (max. 10 digits), e.g. 020.
¤ Click Yes next to Predial area code for local calls through VoIP to activate the function.
Click No to deactivate the function. You will then need to enter the area code for local
calls made via VoIP. Numbers in the directory must always contain the area code for dial-
ling via VoIP.
¤ Click Set to save the settings.
