Figure 6-15 Configuring a Route Pattern for Intercluster Calls
Note The simplified dial plan in this example provides no automatic
fallback or overflow to the PSTN. This capability would require a
route group for each destination, as in previous releases of
Cisco CallManager. You can add manual access to the PSTN in the
standard way. This example shows that the addition of a new cluster
requires no configuration on the existing Cisco CallManagers, only
on the gatekeeper and the new Cisco CallManager.
