2.2 General Functions
2.2.1 Assignment of Internal and External Call
Numbers
Your telephone’s internal number is assigned when the system administrator con-
figures the 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 OpenCom 100/OpenCom X300. 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.
