business related calls and reduces phone bills by only allowing long distance calls over designated
lines.
TRS (Call Barring) can be used in conjunction with Automatic Route Selection (ARS).
• TRS (Call Barring ) classes are set on an extension and trunk basis. Up to 50 TRS (Call
Barring) classes can be assigned.
• Each TRS (Call Barring) class is then assigned to a TRS level. This level is used as the basis
for allowing or restricting calls.
• There are 10 TRS (Call Barring ) levels available: 0 denies all calls, 1-8 may be partially
restrictive per assignments, and 9 allows all calls.
• TRS (Call Barring) can restrict the number of digits dialled (1 to 20 digits limit or no limit).
• TRS (Call Barring) can restrict the use of System Speed Dials (SSDs) for out dealing on a
TRS (Call Barring) class basis; either no system speed dials or limit the range of SSDs.
• TRS (Call Barring) can restrict the use of the star (*) or pound (#) digits on a TRS (Call
Barring) class basis.
The following calling restrictions are also available:
• Forced ARS Restriction (The ARS feature controls outside calls.)

Considerations
• The dialling restrictions included in this feature help prevent unauthorized outgoing calls. It is
possible; however, to program your System to allow SSD to override TRS (Call Barring).
