Alternative Call Routing for Network Bandwidth Management Page 147 of 258

by the same Central Office, PSTN calls can use the trunks at the main office. However, if the two systems are located at a great distance from each other, it may make sense to program the main office to use trunks at the branch office for alternately routed calls.

If there is a location with multiple NXX codes for DID users, it is possible to translate and outpulse calls properly as long as each NXX has a unique DN range. Non-DID users can be reached through the attendant console, by deleting the ALTPrefix and the DN dialed and inserting the digits in the Listed Directory Number (LDN).

When calls are rerouted to use the PSTN instead of the station-to-station IP network, there may be a loss of feature functionality normally available for station-to-station calls. Features that are not available over the PSTN are not available to the user.

This feature does not apply to virtual trunk calls. It only applies to station-to-station calls, and routes them over the PSTN or MCDN network. Virtual Trunk calls already have this feature and can be alternately routed using traditional methods (such as NARS), which is outside the scope of this feature.

Alternative Call Routing for NBWM does not apply to users who are registered in local mode to the Branch Office.

Calls that are in an ACD queue cannot be alternately routed by this feature. These calls remain in the ACD queue until an ACD agent and sufficient bandwidth are available.

Music on Hold is not affected by this feature.

A QoS0038 message prints out when insufficient bandwidth is detected between two zones. A QoS0039 message prints out when the Alternative Call Routing for NBWM feature is invoked.

If a user at a branch office attempts to make a conference call, Alternative Call Routing for NBWM is not invoked.
