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.
• There are 10 TRS levels available: 0 denies all calls, 1-8 may be partially restrictive per
assignments, and 9 allows all calls.
• TRS can restrict the number of digits dialed (1 to 20 digits limit or no limit).
• TRS can restrict the use of System Speed Dials (SSDs) for out dialing on a TRS class basis;
either no system speed dials or limit the range of SSDs.
• TRS can restrict the use of the star (*) or pound (#) digits on a TRS class basis.
The following calling restrictions are also available:
• Forced ARS Restriction (The ARS feature controls outside calls.)

Considerations
• The dialing restrictions included in this feature help prevent unauthorized outgoing calls. It is
possible; however, to program your System to allow SSD to override TRS.
• For more information on ARS/TRS, see the ARS/TRS Reference Manual.
