/mcp[AppID=String][ClusterID=String][NodeID=String]: Unified CM received a corrupted DMRemoteDeviceRegisterUnRegister message in internode communication. Explanation Unified CM examines the incoming DMRemoteDeviceRegisterUnRegister messages to detect values in the message that are outside the normal expected range. Unified CM issues this alarm when the message is determined by Unified CM to contain values outside the normal range. Unified CM has discarded part of the contents of the incoming DMRemoteDeviceRegisterUnRegsister message due to the values that were out of range. This may cause an out-of-synch condition for the registered device's information between the sending node and this node, which in turn can lead to phone calls being routed incorrectly Recommended Action Make a note of the IP address/name of the remote CM node that generated this message. Around the timestamp of this alarm, save the SDL/SDI logs from this node and the remote node for analysis by Cisco TAC personnel. Next, at the first opportunity, restart the Cisco CallManager service on this node to ensure that the registered devices information throughout the cluster are in synch. Also, in Cisco Unified Serviceability, make sure to set the Unified CM SDI logs setting to Detailed to ensure collecting relevant logs should this alarm recur. If this alarm does occur again, contact Cisco TAC to help determine the source of DMRemoteDeviceRegisterUnRegister message corruption. Error Message %UC_CALLMANAGER-6-UnEncryptedCallBlocked: %[Party1_CI=UInt][Party2_CI=UInt] [CallingPartyNumber=String][CalledPartyNumber=String][AppID=String][ClusterID=String] [NodeID=String]: Unencrypted call is blocked because one or both of the parties are non-secure or does not support compatible encryption capabilities and the service parameter BlockUnencryptedCalls is set to true.. Explanation Unencrypted call is blocked because one or both of the parties are non-secure or does not support compatible encryption capabilities and the service parameter BlockUnencryptedCalls is set to true. Recommended Action Informational purposes only; no action is required Error Message %UC_CALLMANAGER-3-RecordingGatewayRegistrationRejected: %[GatewayAddress=String] [Cause=String][AppID=String][ClusterID=String][NodeID=String]: Registration to recording-enabled gateway rejected after multiple attempts; gateway marked out-of-service.. Explanation gateway rejected registration request Recommended Action Cause value indicates reason registration was rejected. Check gateway web service api configuration. After configuration issue is resolved, reset SIP Trunk to attempt registration. Error Message %UC_CALLMANAGER-3-RecordingGatewayRegistrationTimeout: %[GatewayAddress=String] [Cause=String][AppID=String][ClusterID=String][NodeID=String]: No response from recording- enabled gateway after multiple attempts; timeout occurred; gateway marked out-of-service. Explanation Gateway registration request did not complete within the specified time limit Recommended Action Verify network connectivity between CUCM and gateway. Check IP address configuration. After configuration issue is resolved, reset SIP Trunk to attempt registration Error Message %UC_CALLMANAGER-5-RecordingGatewayOutOfService: %[GatewayAddress=String][Cause=String] [AppID=String][ClusterID=String][NodeID=String]: Recording-enabled gateway closed connection to 5/24/26, 3:34 AM System Error Messages for Cisco Unified Communications Manager 15 - Cisco https://www.cisco.com/c/en/us/td/docs/voice_ip_comm/cucm/err_msgs/15_x/ccmalarms15.html 295/343
