/mcpError Message %UC_CALLMANAGER-3-CCDIPReachableTimeOut: %[AppID=String][ClusterID=String] [NodeID=String]: CCD Requesting Service IP Reachable Duration Time Out. Explanation The CCD requesting service detected that it can no longer reach the learned patterns through IP. All learned patterns from this forward will be marked as unreachable (via IP) and to allow calls to learned patterns to continue to be routed until IP becomes reachable again, all calls to learned patterns will be routed through the PSTN. Calls can be routed through the PSTN for a certain period of time before PSTN failover times out. Recommended Action Check IP connectivity and resolve any TCP or IP problems in the network Error Message %UC_CALLMANAGER-3-CCDPSTNFailOverDurationTimeOut: %[AppID=String][ClusterID=String] [NodeID=String]: The internal limit on PSTN failover has expired. Explanation When learned patterns are not reachable through IP, Unified CM routes calls through the PSTN instead. Calls can be routed through PSTN for an internally-controlled duration. When this alarm occurs, the PSTN failover duration has expired and calls to learned patterns cannot be routed. All learned patterns will be purged from Unified CM. Recommended Action Troubleshoot your network to get IP connectivity restored. After IP connectivity is restored, Unified CM will automatically relearn Hosted DN patterns and calls to learned patterns will proceed through IP. Error Message %UC_CALLMANAGER-4-CCDLearnedPatternLimitReached: %[CCDMaxLearnedPatterns=UInt] [SystemLimitCCDLearnedPatterns=UInt][AppID=String][ClusterID=String][NodeID=String]: CCD has reached the maximum number of learned patterns allowed. Explanation The CCD requesting service has limited the number of learned patterns to a number defined in the service parameter, CCD Maximum Numbers of Learned Patterns. This alarm inidcates that the CCD requesting service has met the maximum number of learned patterns allowed. Recommended Action This alarm displays the value that is configured in the Cisco CallManager service parameter, CCD Maximum Numbers of Learned Patterns, as well as the maximum number of learned patterns that are allowed by the system (an internally-controlled maximum). Consider whether the specified maximum number of learned patterns is correct for your deployment. If it is too low, compare it with the number shown in the SystemLimitCCDLearnedPatterns in this alarm. If the Max number is below the System Limit, you can go to the Service Parameters Configuration window and increase the CCD Maximum Numbers of Learned Patterns service parameter. If the Max and System Limit numbers match, the system is already configured to run at capacity of learned patterns; no action is required. Error Message %UC_CALLMANAGER-5-DbInsertValidatedDIDFailure: %[e164DID=String][grantingDomain=String] [AppID=String][ClusterID=String][NodeID=String]: The Insertion of an IME-provided E.164 DID has failed. Explanation A failure occurred attempting to insert a Cisco Unified Active Link learned DID Recommended Action Verify the DID and the granting domain. Check other associated alarms. Verify the database integrity. 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 284/343
