Use authorization code to control the calling privileges of system users. Authorization codes extend control of calling privileges and enhance security for remote access callers. You can use authorization codes to:

• Override a facilities restriction level (FRL) that is assigned to an originating station or trunk

• Restrict individual incoming tie trunks and remote access trunks from accessing outgoing trunks

• Track Call Detail Recording (CDR) calls for cost allocation

• Provide additional security control
