Hi,

As per

http://www.cisco.com/c/en/us/support/docs/voice-unified-communications/unified-communications-manager-callmanager/100982-ipcerror.html#P1

Error: CM Down Features Disabled

When you make calls, the Cisco IP Communicator/IP Phone displays this error message: CM Down Features Disabled.

Solution

This error message indicates that the call preservation feature is active because the application has lost its connection to CallManager.

The workaround for this or any other invocation of the call preservation feature is to hang up manually. If the phone does not return to normal on-hook behavior (all lines shown while idle, softkeys appropriately displayed, and responsive to user input), restart the Communicator application or the Cisco IP Phone.

If the above workaround did not fix the issue, it is recommended that you change the Station keepalive parameter to 60 or to its maximum allowed.

Note: Make sure that the IP phone can reach the Cisco Unified Communication manager. The IP reachablity issues can occur because of IP routing, VLANs, or multiple DHCP servers in the same network. Multiple DHCP servers can create problems if they assign a different subnet to the IP phone from which the IP phones cannot reach the CUCM server; this results in similar errors.

IDLE CPU is 90+ that means CPU is free..

Check connectivity between IP Phone and CUCM servers wise versa..

Hi,

It look like a connectivity problem or the call manager service is down, Did you check both?
