When I change the name of the router, the phone stops working so I backed out. Realized that I have to change the Cisco Unified CM Administration - Device- gateway to the new name. Anywhere I have to modify in the Unified CM to make the router name change? Thanks for the input.
Could you explain what you mean by phone stops working? Is this a MGCP gateway, if yes, when you change the hostname, the name needs to be updated on UCM under Device -> Gateway else the gateway wont register.

Thanks for the answer, George. That what I did but the phones were not working. Is there anything else I should make the modification beside Gateway ?
Thats all you have to do, change the name on the router and then in UCM. If might take a little bit to re-register. You could try resetting the gateway from UCM and wait till it registers. If it doesnt, go to the router and issue no mgcp/mgcp and see if it registers.
