Did you by any chance change the IP address of the CRS server. IF so, then you could be facing the know problem CSCdy82034. Check the bug ID in the bug tool kit on www.cisco.com for the solution . Re-installing the CRS server will help the problem to be solved in this case.
If this is not the case then, it could be due to user profiles.
Do the following to resolve it:
1.Creating the user and assign the devices on Callmanager.
2. Go to the CSQ Resource menu,

4. Reboot the server.
5. Now log in to the IP Phone agent using the same username and password.
With this you should be able to successfully login to the IP phone agent.
