© 2006 Cisco Systems, Inc. All rights reserved. CIPT1 v Summary Cisco Unified CallManager routes internal calls by matching the registered directory number to a destination. External calls do not have a registered directory number, and Cisco Unified CallManager will search for a matching pattern in the route plan. Route groups are a logical grouping of device gateways and trunks. Route lists consist of an ordered list of route groups. You use external route patterns for routing off-cluster calls. External route patterns can point to either an individual gateway or a route list. Cisco Unified CallManager uses closest-match routing. A basic route plan consists of voice gateways and trunks, route groups, route lists, and route patterns.
