consultation on cluster CUCMs

[leoandino]

Hi...

Good afternoon, I have the following question;

What happens when you change the IP (different network segment) of the CUCM Publisher that there is a cluster of CUCMs?

Are there problems are present?

regards

Hi,

it is crucial that you follow the right process as outlined here:

http://www.cisco.com/c/en/us/support/docs/voice-unified-communications/unified-communications-manager-callmanager/116292-install-cucm-00.html

or here

http://www.cisco.com/c/en/us/td/docs/voice_ip_comm/cucm/install/7_0_1/ipchange/ipchg701.html

or the version that belongs to your CUCM Version. Otherwise the cluster is broken and you will have much work.

Hi.

+5 to the suggestion here above.

The main thing before you do any action on CUCM PUB, take a full backup to keep safe in case of disaster :)

In addition to great posts by my colleges (+5), review any services and integrations the pub is responsible, for example if you have TFTP service running on it make sure you update your DHCP scopes, if you have call accounting apps pointing to it, do the same, and on and on.
