External/Internal Calling
Line Seizure
When dialling internal or external call numbers, it is critical whether your system
administrator has configured an internal or external preferred key for your tele-
phone.
Internal preferred key: the internal preferred key (standard configuration)
requires entering a code for seizing external lines when dialling an external call
number. The system administrator will inform you what the code is.
For enquiries and call diversions to external call numbers, you must also prefix
the external call number with a line seizure code.
External preferred key: you can immediately dial an external call number
(without entering a line seizure code) by pressing the
A receiver key. This
preferred key is primarily configured if you have to carry out many external
calls.
Line Seizure via “Direct Call Key with Signalling”
“Direct call keys with signalling” can be configured on your telephone. Dialling via
“direct call keys with signalling” is done the same way as entering a call number.
For all procedures described in this chapter, you can select “direct call key with sig-
nalling” from the key menu instead of entering a call number. Open the key menu
with a short or long key press on the C key
C (see also page 25).
Line Seizure via “Team Direct Call Key”
“Team direct call keys” can be configured on your telephone. You can use a “team
direct call key” from the key menu to directly call the programmed destination.
Open the key menu with a short or long key press on the C key
C (see also
page 25).
