Internal and External
Telephone Numbers
The internal number of your tele-
phone is assigned when you con-fig-
ure your communication system.
The telephone number is linked to
the call key
of your terminal,
which means you receive calls on
this key. You can have several inter-
nal telephone numbers on different
call keys on the OpenPhone 63 and
65. The external telephone
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 telephone numbers
The above example shows that the
system’s external telephone num-
bers are first stored in the OpenCom
100. The terminals can be reached
selectively by means of call distribu-
tion of the numbers to the internal
numbers (call keys).
As you see, telephone 1 and tele-
phone 2 both ring when a call is
made to the number 4701 1234.
At the same time, terminal 1 can
also be reached on the number
4701 1678.
