Toll Restriction Service

Description
Toll Restriction Service (TRS) allows access levels, including the prohibition of long distance calls or
after-hours calls, to be assigned to specific extensions or CO lines. This minimizes non-business
related calls and reduces phone bills by only allowing long distance calls over designated lines.
TRS can be used in conjunction with Automatic Route Selection (ARS).
• TRS classes are set on an extension and trunk basis. Up to 50 TRS classes can be assigned.
• Each TRS class is then assigned to a TRS level. This level is used as the basis for allowing or
restricting calls.
