Basic functions
Device key
The device key is stored with your internal device call number (main phone number). It is labelled
with your internal call number (or alternatively with a text programmed by your system administra-
tor).
INTERNAL keys and EXTERNAL keys
Besides your device key other call keys can be set up on your phone. These keys allow you to make
and receive internal and external calls. Each of the keys has its own call number.
Calls from internal subscribers are signalled on INTERNAL keys. In the case of an EXTERNAL key your
internal call number is assigned to an external call number under which you can be reached from
the outside. Several external call numbers may be assigned to the key.
To make a call, seize one of your INTERNAL/EXTERNAL keys by pressing the call key; you can then
make an external or internal call immediately (depending on the system setting), see the section
entitled “Making internal/external calls” on page 40ff.
Direct call key with signalling
“Direct call keys with signalling” are special call keys that allow a connection to be set up to one des-
tination partner only. When you are making a call using a “direct call key with signalling” your pho-
ne’s other call keys remain free. This means other callers can reach you.
MULTIPLE key
A MULTIPLE key is a call key (device key or INTERNAL/EXTERNAL key) programmed on several pho-
nes. This means that MULTIPLE keys have the same (internal) call number. The phones involved
represent a team; calls to one team member are signalled to all the MULTIPLE keys on the phones of
the other team members.
A MULTIPLE key is operated in the following way:
• When a call is made to a team member you can use the key to answer the call in his place.
• You can use the key to make calls yourself, in which case you will be occupying the team
member’s call number.
• Depending on whether your MULTIPLE key is a team member’s INTERNAL or EXTERNAL key you
can set up internal or external connections using the MULTIPLE key.
For more information please refer to the section on team functions on page 87ff.
