Jabber Service Discovery, when having multiple CUCM cluster.

[ShankarP]

Hi Experts, is it possible to discover services thro DNS, when deploying multiple cluster within same domain. Thanks

Eg: User A should be directed to Cluster A and User B should be directed to Cluster B.

Yes set up service discovery using SRV records, you will need to enable and configure ILS on the clusters to support Jabber user registering to their Home Cluster.
Once the users is authenticated into the service domain CUCM will search for the users home cluster through ILS and register the user there.
