Use the Facility Restriction Levels (FRL) feature to restrict some types of calls to specific users. For example, you can use FRL for some users to place international calls, but for other users to place only local calls.
Facility Restriction Levels supports the following capabilities:
Alternate Facility Restriction Levels (AFRL)
Use AFRL to assign a second set of FRLs within a route pattern or to lines and trunks. For example, you can use an AFRL to disable the ability to place long distance calls when the office is closed.
Traveling Class Mark (TCM)
The system uses TCM to pass the FRL of a caller from one server to another server. The server that receives the FRL uses the FRL to determine the calling privileges that are assigned to the user.
