I'm running CRS 4.0.4 with callmanager 4.2.3. My desktop agents work fine and I was going to use IP phone agent as a backup for anytime a PC is down. When I select the service on the phone I get the error "host not found." I am using the callmanager IP in the service URL and my callmanagers are identified in the callmanager menu on the CCM by their IP addresses. I have restarted the TFTP service and reset the phones. I have the desktop agent closed on the PC while I am trying to login to the phone agent. What else could be causing my problem?
I have this problem too.
