Remember to change the IP address in a number of configurations where the IP address is hard coded.

For example,

- Under Enterprise parameters, there are a number of URLS with the hard-coded IP address.

- Under Services (address book or fast dials)

- TFTP Service

- Host and LMHost files

- Your voice gateways MGCP or H323 configs

Having just recently gone through this with CCM 4.1(3), I agree with all that eug-c stated. In addition, if you are using Unity, you will need to reconfigure the TSP settings on the Unity server. In my particular situation, I did the following. On the Unity server, go to Control Panel, Phone and Modem Options, Advanced and select Cisco Unity-CM TSP. From there select configure and you should see the IP address of your call manager(s). Change these and restart the Unity services and you should be good.

Hope this helps.
