CUCM Route Plan: Understanding Route Lists and Route Groups

Scenarios calls between Phoenix and Detroit..

Detroit WAN Devices (Primary)

*Top Down/Circular Distribution Algorithm

  • Detroit Intercluster Trunk

PSTN Devices (Backup)

  • Via 2810 ISDN Gateway

*If a Device is used in a Route Pattern, it disappears from anything else.

Add New Route List ‘Ways to Detroit’

  • Add Route Groups to Route List
  • Detroit WAN Devices (Primary)
  • PSTN Devices (Backup)

Then under Route Pattern add the Route List ‘Ways To Detroit’ (Which contains the 2 Route Groups WAN and PSTN)

Transformations to follow when Called/Calling information is sent across the PSTN as normal dial plan for WAN calls will not work over the PSTN
