Telephoning General Functions Assignment of Internal and External Call Numbers Your telephone's internal number is assigned when the system administrator configures the OpenCom 100 / Aastra 800 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). External telephone numbers Call distribution scheme Internal telephone numbers on the call keys 4701 1678 4701 1234 4701 1345 4701 1456 47 Telephone 1 48 49 Telephone 2 50 Communications system 51 Telephone 3 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 / Aastra 800. 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 15 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 92). 46
