CUCM 8.5 Cluster and Dial Peers Configuration

                   Hello guys!

    When adding a Subscriber server to an existing Publisher in order to create a cluster in the Cisco Communication Manager existing group in the Administration page, if the Subscriber is first in the CUCM group in order to take care of call control while the Publisher deals with the dayabase:

1. Does the dial-peers that route calls to the CUCM need to be modified? For example, if dial-peers points to the session target ipv4 of the exisiting Publisher, but now the Subscriber is the one dealing with call control, does the seassion target ipv4 of those dial peers need to be changed to the Subscriber's ip address?

2. If the voice port (for pots dial-peers) or the session target (for voip dial-peers) are not responding and if there is another dial peer with the same or less specific destination-pattern, the router should continue to that dial-peer correct?

Thanks in advanced for any help guys!

1. They don't need to but the preferred dial peer will control which CUCM server will process the call, so you should adjust your dial peers to have the preferred dial peer use the SUB rather than PUB

2. Correct
