Symptom:
There is a subdomain dependency in the CCM cluster. For example, with below setup, ccm1 seems to be querying the  ccm2.subdomain1.cisco.com  instead of ccm2.subdomain2.cisco.com  when they are in different domains (subdomain1 & subdomain2)

        ccm1 (publisher)    subdomain1.cisco.com  
        ccm2 (subscriber)  subdomain2.cisco.com  
        ccm3 (subscriber)  subdomain2.cisco.com  

Workaround > Use CNAME record on the DNS Server for CUCM 6.x and "A" records on CUCM 7.x
Conditions:
CUCM 6.x & 7.x
