Dialling internal destinations via external call numbers
Internal users can also reach internal destinations by dialling an external call
number with the help of an allocation table in AIMS. This is particularly helpful
when dialling with the aid of a phone book directory. In this way an internal and an
external call number do not have to be stored in the phone book directory.
When the PBX recognizes that it is an external call number, the call number is
checked against the entries in the allocation table (CM_2_1_12). If the dialled call
number matches an entry, the assigned internal call number is dialled instead of
the external call number. If no match is found, the external call number is dialled.
Note:
If the dialled number does not contain a country code, the country code defined in
the corresponding AIN region (CM_1_2_11) is automatically added to the call
number before the table is checked. This makes it possible to dial the call number
with or without the country code.
Example Switzerland:
[1]
The call is routed to external if no entry is found for the dialled number in the allocation table.
[2]
The call is routed to the internal destination which is assigned in the allocation table of the dialled exter-
nal number.
