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 dial-
ling numbers from the directory and other
lists. Exceptions: Numbers for which you
have defined dialling plans (page 124).
