[cisco-voip] CMM with two CUCM clusters and MGCP

[Lelio Fulgenzi]

you'll have to decide how to send calls back and forth from each cluster. your goal is probably to make it as simple for the users as possible. here's one option: 


    • on cluster A, create a route pattern 2XXX that sends calls to the new cluster over the inter cluster trunk 
    • as you migrate phones from cluster A to cluster B, on cluster A, move their DN to a non-reachable partition 
    • on cluster B, create a route pattern, *77.2XXX, that drops the *77 and sends the 2XXX over the intercluster trunk to the old cluster. 
    • phones on cluster B that have not been migrated will have a CFUR destination of *772XXX 



you'll have to ensure CSS and partitions are set properly so calls can be made properly. 




one thing to remember is to ensure that the CSS of the trunk does not have access to a partition that contains a route pattern that can send the call back to itself. this will help prevent loops.

hmmm... CFUR might come in handy... so basically I just register CMM to the new CUCM cluster and then create 2XXX route pattern (this is the numbering plan) to the old CUCM cluster (using inter-cluster trunk) and each device to have CFUR to the same DN, right?

call forward unregistered. very very handy for stuff like this.

Thanks for your replay Pavan. Yes this is one possible scenario but the migration of users is completely random so I cannot determine some pattern and to make those DNs to be routed to the new cluster. Plus, when the migration of the users is complete we need to shutdown old cucm so I then I would have to register the CMM modules on the new CUCM and this means some downtime and reconfigurations.

I would keep the CMM registered to the old ccm and route calls to it from the new ccm back to the old ccm. 
Inbound calls from cmm need to be routed to the new ccm from the old one based on some characteristic of your 150 user batch or by using cfur on old ucm. 

Curious if others have a better idea !

> Hi, I have a bit of a problem... I have a customer that migrates from CUCM 6.1 (two server cluster) to CUCM 8.6 (two VM cluster). They have two CMM line cards registered with the old CUCM cluster using MGCP. Now I have to do a migration of users/devices to the new cluster in several phases (150 users per phase) and they will be using the same numbering plan on both clusters. My problem is how to register the CMM modules on both clusters and how to manage the incoming calls when both clusters will have the same numbering plan...
