13.5 Prefix
The prefix" function enables a number to be dialled automatically before
the actual phone number. This is mainly implemented when using
call−by−call numbers. Various area access codes can be assigned to a
call−by−call number or you can dial the same call−by−call number before
every call. In the case of calls dialled from the phone book in which the
area access code stored is the same, the stored call−by−call number is,
naturally, also prefixed.
Up to three different call−by−call numbers, each with 5 digits, can be
stored. The automatically prefixed call−by−call numbers do not appear in
the display preceding the dialled number.
Note: If the Call button  is pressed first and then a phone number
dialled, no stored call−by−call number is prefixed.
