INTERNAL ARS DESTINATIONS
ARS mechanisms can handle internal destinations.
INTERNAL CALL FORCING
When a user tries to call a correspondent (connected to the same Alcatel OmniPCX Office system or
belonging to the same private network) by dialing the correspondent's public number, the ARS mecha-
nism converts the public number into an internal number, and an internal call is made.
Configuration example
"ARS Table" configuration:
"Trunk group list" configuration:
In this example:
- the public call from user 2102 to user 2103 (by dialing 08840722103) is converted into a local
call by replacing 8840722 by 2; the system therefore sends the number 2103.
- the public call from user 2102 to user 1101 (by dialing 08840721101) is converted into a local
call by replacing 8840721 by 1; the system therefore sends the number 1101 over trunk group 2
(as the 2 sets do not belong to the same PABX).
