Call Rerouting for Virtual Tie Lines 91
Figure 15 Sample Dial Plan Entries for Rerouting VTL Calls
Explanation:
The TableEntry Create command specifies that when a user on the local
NBX system dials a six-digit number beginning with the digits 72, the call
is routed via route 6, which is the route that normally contains only the
VTL extension list (*0006).
To allow VTL calls to be rerouted, route 6 is configured to use both the
VTL extension list and the Line Cards extension list (*0001). Calls that use
route 6 can be completed using devices in either of these extension lists.
There are four DestinationRouteOperation lines. The first two lines specify
the primary way to handle the call, using VTL methods. The last two lines
specify the backup way to handle the call if the first method fails.
