144 Alternative Call Routing for Network Bandwidth Management
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 are 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.
Feature interactions
Call Redirections
The Alternative Call Routing for NBWM feature works with Call Transfer,
Call Forward All Calls, and Conference. Redirection operates as if the user
dialed the ALTPrefix manually.
Multiple Appearance Directory Number
If telephone endpoints sharing Multiple Appearance DNs (MADN) are
configured in different zones, then this feature handles the call in the same
way that Network Bandwidth Management does. The zone number of the
telephone that is prime for the DN is the only zone considered.
Network Bandwidth Management
The Alternative Call Routing for NBWM feature does not detect insufficient
bandwidth. It reacts to insufficient bandwidth detected by the Network
Bandwidth Management and Adaptive Network Bandwidth Management
features. For more information on these two features, refer to IP Peer
Networking Installation and Commissioning (NN43001-313) .
Network Class of Service
The telephone calling must have an NCOS assigned that allows the call
to use the alternate route.
