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.

At the NRS:

•

Create a CDP entry for the ALTPrefix in the branch office gateway.
