Cisco Call Manager (CUCM) - Route Groups, Route Lists, Route Patterns!! - Part 1

About this video

A technical CUCM dial-plan lesson framed with a Star Wars scenario: phones inside the Death Star can call each other, but outbound calling was never configured, so Captain Tarkin cannot call the Mos Eisley Cantina on Tatooine to book an event. Chuck explains the hierarchy of route group, route list, and route pattern. A route group is a container grouping gateways and trunks; a route list is a prioritized list of route groups; and a route pattern can point either directly to a gateway/trunk or to a route list. He gives three reasons not to bypass the hierarchy even for simple setups: it follows Cisco best practice, it allows scalability, redundancy, and failover by adding devices to a group, and route lists enable digit manipulation per route group instead of creating multiple route patterns. In Call Manager he configures two route groups, one for the Leia CUBE and one for the Luke CUBE, via Call Routing > Route/Hunt > Route Group, noting distribution options such as top-down and circular. He then introduces route lists as the ‘bread and butter’ of the design, with the Leia PSTN path as primary and the Luke PSTN path as a secondary backup that costs far more per minute and requires a different digit handoff. Chuck notes the channel had reached 7,500 subscribers and that a CCNA giveaway was ending on the 15th at 11:59 p.m. Central.

Key takeaways

• Route group = group of gateways/trunks, route list = prioritized list of route groups, route pattern = dialed pattern that points to a route list or directly to a device
• Avoid pointing a route pattern directly to a trunk/gateway for production designs — you lose scalability, redundancy, and failover
• Route lists provide digit manipulation per route group, avoiding duplicate route patterns for gateways with different digit requirements
• Design a primary and backup outbound path: in the example, Leia is primary and Luke is backup, but Luke is much more expensive per minute
• Configure route groups in CUCM under Call Routing > Route/Hunt > Route Group and add the already-configured SIP trunks to each group
