Cisco Call Manager (CUCM) - Route Groups, Route Lists, Route Patterns!! - Part 2

About this video

Part 2 of a Cisco Call Manager (CUCM) tutorial on outbound call routing, sponsored by INE. With route groups Luke and Leia already built in part 1, Chuck configures a single route list (the Empire Route List): he enables running it on all active Unified CM nodes, then adds the route groups in priority order and sets per-group digit manipulation, which he presents as the key advantage of route lists. For primary gateway Leia, the requirement is E.164 delivery, so he discards digits with the NANP pre-dot setting and prefixes +1. For failover gateway Luke, whose PSTN has an odd requirement, he prefixes 818181 instead. He then creates one route pattern (dialing prefixed with 8 to signal an external call, placed in the Tatooine partition) pointing at the route list, showing that one pattern serves both providers instead of duplicating patterns per transformation. He demonstrates the Route Plan Report for verifying the whole chain, then tests live in a GNS3 lab with two CUBE routers: calls go out Leia with +1 prepended, and after he swaps the priority, out Luke with 818181 prepended.

Key takeaways

• Route lists sit between route patterns and route groups: one pattern can reach multiple gateways in priority order
• Digit manipulation belongs in the route list per route group, avoiding duplicate route patterns for different PSTN requirements
• Primary path example: discard pre-dot and prefix +1 to deliver numbers in E.164 format; failover path example prefixes 818181 as that provider requires
• If the primary trunk is down, busy or out of concurrent sessions (he illustrates with 30 sessions), calls roll to the next route group
• The Route Plan Report is his go-to verification tool, and he proves the setup with live test calls through two CUBE routers in GNS3
