asked on Changing DNS on Cisco Call Manager
Our Current Version of Call Manager is "Active Version: 5.1.1.3000-5 " I have inherited the IT position at the facility and can get into the box but because of a server failure we are working through we need to change the DNS on our call manager server to a new address. What are the commands and where do I change them. I can get into the box at a console level and also through web administration to the OS administration. The Ethernet settings only have options for me change the IP and subnet mask. Any help is greatly appreciated we have Pilot Points that are not working and we are hoping this will resolve the issue, plus it needs to be done anyways since the DNS servers are no longer functioning. Also there are two callmanager servers will these settings filter over or will I have to change them on both servers.

I read a few things that mention this should be on a windows box which would be no problem except ours are the cisco appliance versions.

Yes the IPs of our DNS changed. I had to seize roles using ntdsutil and the servers that are now handling DNS are running other apps and have established IPs so i couldn't just change them. I will try those and let you know. OK was logging in while typing because we are a call center I will not be able to try this until after 7PM tonight when the phones are unoccupied. In the mean time would this affect pilot points not seeing phones and bypassing them like they weren't logged into the network?

The domain and hostname are all going to stay the same. I changed the DNS on one of the 2 callmanager boxes and am now unable to get into the device using the web interface. Do i have to reset or do anything else after I made the DNS changes?

Coming in this morning I also have reports that no can make calls and that the phones are unable to see callmanager.

The commands worked Pilot Points are working again I just want to add as a note to anyone else who comes across this that you should restart callmanager afterwards. Cisco got on the phone with us this morning and made that clear as well, any time network changes are made a reboot is a very good idea.
Hello Experts,
After the DNS update on the 10.x call manager Publ, Sub's does it required to reboot the whole cluster. ?
