NCR is especially useful for multisite call center operations in which the Best Service Routing (BSR) feature is activate as the number of PRI B-channels needed for call interflows is reduced. The queue-to best vector step can be used to interflow ISDN calls between Communication Managerover the PSTN. This method provides the best approach for balancing loads across a multisite environment and is more cost effective and accurate than pre-delivery routers.
NCR is activated by the queue-to best vector step when the BSR feature determines a BSR location is the best BSR location and that location is administered with the Net Redir option set to y on the BSR Application Table screen.
Note:
The administered Interflow VDN field on the Best Service Routing Application screen must be a PSTN or VPN endpoint number without a trunk/ARS/AAR access codes included. For some PSTN switch dialing plans, the long-distance access code. For example, 1 in the United States must be prefixed to the PSTN number for the call to be successfully routed by the PSTN switch.
As shown in the following example, the Best Service Routing Application Plan screen must include locations that have the Net Redir field set to y.
BEST SERVICE ROUTING APPLICATION
Number: 1 Name: Maximum Suppression Time: 60 Lock? y
Num Location Name Switch Node Status Poll VDN Interflow VDN Net Redir?
1 Omaha 95552011 3035551211 y
2 Paris 95552022 18005551234 y
3 Sydney 95552033 18665553456 y
An appropriate vector is then used to identify a BSR best location and NCR is activated by the queue-to-best vector step.
