Configuring Standard Local Route Group CUCM

Configuring Standard Local Route Group CUCM

Standard Local Route Groups(sLRG) is a feature which helps in reducing the complexity and maintenance of the numbering dial plan when you have a large number of locations/sites. It can be used in a scenario where the dial plan is uniform across the locations.

For example – In Unites States, lets say we have 5 locations like New York, Honolulu, San Francisco, Chicago and Seattle. Emergency number in United States is “911” across all the sites. Ideally, if you do not use LRG, you have to create “911” pattern for 5 sites i.e., 5 Route Patterns. When you use LRG, you just need to create one 911 pattern which will work for all the 5 sites. Similarly for 7 Digit Dialing, 10 Digit Dialing and 11 Digit Dialing, you can use LRG to decrease the number of Route Patterns and make your dial plan simple and effective.

How to achieve it?

(Note : Assuming that you have already create Route Groups and Device Pools for each of the above mentioned sites and associated the local gateways to their respective site)

Create Route List

  • Go to Call Routing > Route/Hunt > Route List > Add New
  • Name > 911_Global_Emer_RL
  • Description > 911 Global Emergency Route List
  • Cisco Unified Communications Manager Group > Select the CUCM Group from the Drop Down
  • Click on Save
  • Check Mark > Enable this Route List (change effective on Save; no reset required)
  • Click on Add Route Group
  • Route Group > Select “Standard Local Route Group” from the drop down menu
  • Click on Save
  • Click on Reset

Modifying Device Pools

  • Go to System > Device Pool > Click on Find
  • Locate New York Device Pool and go to Device Pool Configuration
  • Local Route Group > Select New York Route Group from Drop Down Menu
  • Click on Save
  • Go to System > Device Pool > Click on Find
  • Locate Honolulu Device Pool and go to Device Pool Configuration
  • Local Route Group > Select Honolulu Route Group from Drop Down Menu
  • Click on Save
  • Follow the same process for  San Francisco, Chicago and Seattle and associate their Route Group to their respective locations.

Creating Partitions

  • Go to Call Routing > Class of Control > Partition > Add New
  • Name > 911_Global_Emer_PT
  • Description > 911 Global Emergency Partition

Associating Partitions to Calling Search Space

  • Go to Call Routing > Class of Control > Calling Search Space
  • (Associate “911_Global_Emer_PT” to the Calling Search Space that you would allow users to dial 911 numbers from their IP Phone)

Create 911 Route Pattern

  • Go to Call Routing > Route/Hunt > Route Pattern > Click on Add New
  • Route Pattern > 911
  • Route Partition > 911_Global_Emer_PT
  • Gateway/Route List > 911_Global_Emer_RL
  • Check Mark > Urgent Priority
  • Click on Save

That’s all!! In the similar way, you can achieve 7 Digit Dialing, 10 Digit Dialing and 11 Digit Dialing as well.
(Note: Please do not make attempt to dial 911 number if there is no emergency.    🙂    )
Hope this helps!
