to save your settings.

Setting area code predialling

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).
