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 trunk key
of your telephone, which means you
receive calls on this key. You can have several internal call numbers on
different trunk keys on your system telephone. The external call numbers at
which you can be reached are assigned to the trunk key.
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 communications system. The devices can be reached selectively
by means of call distribution of the numbers to the internal numbers. 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.
