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:

Configure the following settings in the 

 area for call forwarding via VoIP: 

If you activate 

, the external parties you are toggling between will be connected 

when you press the end call key 

a. Your connections with the parties will be termi-

nated. 
To learn how to forward a call when you have activated 

 please see page 48.

Define the protocol (the contents of the "Refer To" information) that should be used with 

preference when forwarding calls:

This protocol is recommended for "closed" networks (internal company and business 

networks).

 

This protocol is recommended when the base station is connected to the Internet via a 

router with NAT. 

If you activate 

, 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 

. 

¤

Now click 

 to save your settings.

On the base station, save the complete code (with international code) for the area in which 

you are using the phone. 
For 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 setting your phone to prefix this code 

for all VoIP calls made in the same local area. 
For calls made via VoIP, 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. Exceptions: 

Numbers for which you have defined dialling plans (page 149).
