Example of an alternately routed call between a branch office telephone in Normal Mode and
a main office telephone
Telephone B calls Telephone A (the user dials DN 5262). In this example, the
call alternately routes to the PSTN. (The PSTN telephone number of
Telephone A is 613-966-5262.)
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.
