Assignment of Internal and External Call
Numbers
Your telephone’s internal number is assigned when the system administrator
configures the Forum 500 / Forum 5000 communications system. The call
number is linked to the call key
g
of your telephone, which means you
receive calls on this key. You can have several internal call numbers on
different call keys on your system telephone. The external call number(s) at
which you can be reached is (are) assigned to the call key(s) (with the internal
number).
Example of the assignment of internal and external call numbers
The above example shows that the system’s external call numbers are first
stored in the Forum 500 / Forum 5000. The telephones can be reached
selectively by means of call distribution of the numbers to the internal
numbers (call keys). As you see, telephone 1 and telephone 2 both ring when
a call is made to the number 4701 1234. At the same time, telephone 1 can
also be reached on the number 4701 1678.
Signalling on the Call Keys
“Call key” is the general term for all keys of your telephone which you use to
make calls and are called. These are feature keys (please refer to page 15 and
page 16 also) or call keys with team functions (team keys or direct call keys,
please refer to the chapter
Managing Calls in a Team
starting on page 96).
