Example of an alternately routed call between a Branch Office telephone and another Branch
Office telephone
Telephone B in the BO2 zone calls Telephone F in the BO1 zone (the user
dials 6020). In this example, the call alternately routes to the PSTN. (The
PSTN telephone number of Telephone F is 506-348-6020.)
Configuration required Configure the following:
At the main office:
• Use one of the dialing plan software packages to process the call, such
as CDP or NARS.
• Provision an ALTPrefix for the BO2 zone.
• Provision the ALTPrefix as a Steering Code at the main office. Build a
Route List Index (RLI) so these calls go to the virtual trunk or configure
the Vacant Number Routing feature to do the same.
At the Branch Office:
• Provision the ALTPrefix as a steering code. Build a Route List Index and
DMI associated with this steering code that alternately routes these
calls to the PSTN.
