166 Alternative Call Routing for Network Bandwidth Management
Figure 67
Digits dialed and outpulsed with Alternative Call Routing for NBWM
1. IP Phone User B in the BO2 zone dials IP Phone A in the main office
zone (DN 5262) (action labeled 1 in Figure 66 "Call between a branch
office telephone in Normal Mode and a main office telephone" (page
164)).
2. The main office Call Server determines there is insufficient bandwidth
between the two zones.
3. The Call Server inserts the ALTPrefix configured for the BO2 zone prior
to IP Phone A’s telephone number, dialed by the user.
Example: ALTPrefix assigned is 222. The dialed number becomes 222
5262.
4. The call is routed to the virtual trunk by CDP or VNR. The virtual trunk
sends a request to the NRS for address resolution. The digit str ing sent
to the NRS contains the ALTPrefix. The NRS returns the IP address of
the branch office endpoint to the virtual trunk.
5. The virtual trunk places the call to the branch office.
