Why does the Cisco Unified MobilityManager service on the IP phone give an error?
A. The service may be giving an error if the service is not subscribed or the directory number (DN) is not correctly configured. In the Service configuration of Cisco Unified CallManager, be sure to check the Parameter Required checkbox. The parameter should have the value “dn” (lowercase). You can also collect the snoop logs for the http request in the Mobility server using following command: tethereal -i eth0 -f ‘port 8081’ -x -d tcp.port==8081,http If there is still a problem, provide the cmmApp.log.
