Programming Automatic Route Selection (ARS) Restriction

(For Hybrid/PBX mode only)

As an additional security step, network dialing for all extensions, including messaging port extensions, should be processed through ARS using dial access code 9.

All ports on the communications system that are programmed as VMI ports must be:

  • Assigned an FRL of 0
  • Outward Restricted
  • Assigned Disallowed List 7

This combination of restrictions is designed to prohibit all Outcalling.

To prevent toll fraud, ARS FRLs should be established, using:

Each extension should be assigned the appropriate FRL to match its calling requirements.

If...

Then...

A messaging port extension is not used for Outcalling

It should be assigned to FRL 0 (the factory setting)

Outcalling will be used for the MERLIN Messaging System

For Release 2 or later, Program the appropriate ARS FRL for each messaging port extension as follows:

  • Port 2 only on a 2-port system
  • Port 4 only on a 4-port system
  • Ports 5 and 6 only on a 6-port system
  • Ports 7 and 8 only on a 8-port system
  • Ports 9 and 10 only on a 10-port system
  • Ports 11 and 12 only on a 12-port system

For Release 1 and 1.1, ports to be unrestricted or toll restricted are:

  • Port 2 only on a 2-port system
  • Port 4 only on a 4-port system
  • Port 6 only on a 6-port system


Note:

 

Refer to your communications System Planning Form containing Call Restrictions and Lists information to identify the appropriate FRLs for system ports and other restrictions.
