I have two data centers and will be installed CUCM_PUB and CUCM_SUB in each location. and I want to install CER servers in each location as below combination but cannot find out CER requirement from CCO.
-data center1, CUCM_PUB, CER_PUB
-data center2, CUCM_SUB, CER_SUB
-can I install CER servers with the above combination?
-what is CER RTT (or something else) requirement between CER Publisher and Subscriber?
-CUCM RTT requirement is 80ms (after version 6.1). Is CER requirement belonging to CUCM?
***the CER subscriber requirement as per CER admin guide,
'Consider installing the standby server in a physically separate location from the primary server, and on a separate subnet not separated by a WAN link'
