/mcpError Message %UC_CALLMANAGER-4-ILSDuplicateURI: %[URI=String][RouteStrings=String][AppID=String] [ClusterID=String][NodeID=String]: Duplicate URI Found in ILS network Explanation A duplicate URI has been found in this ILS Network. Recommended Action Check if there are duplicate URI entries learned from remote ILS clusters. Determine which Cisco Unified Communications Manager cluster needs to be changed so that there is no duplicate URI. Reconfigure the remote serves to ensure the URIs configured are unique within a ILS network. Error Message %UC_CALLMANAGER-4-CallingNumberNotConfiguredOnCallingDevice: % [CallingNumberNotConfigured=String][DeviceName=String][SourceIPAddress=String][AppID=String] [ClusterID=String][NodeID=String]: A call was attempted from a number not configured on this SIP phone Explanation A call was attempted from a calling number that is not configured on the SIP device. The incoming Calling number did not match any of the configured lines on the device. For security reasons Communications Manager refused the call. Recommended Action Validate that the IP address from which the call was made matches the current IP address of the device. Reset the device and verify it is able to obtain the correct configuration file from TFTP. Check for a mismatched CTL or ITL file which can prevent the device from accepting the configuration file provided by the TFTP server. This may also be indicative of a security issue in progress; proper investigation is highly recommended Error Message %UC_CALLMANAGER-6-CallingLineNumberInconsistenciesCorrected: % [InvalidCallingNumberSentByDevice=String][CallingNumberAfterCorrection=String] [DeviceName=String][SourceIPAddress=String][AppID=String][ClusterID=String] [NodeID=String]: Inconsistent line numbers found in received SIP headers were corrected. Explanation The system received SIP headers containing one or more line numbers not configured on this device. The received SIP headers also contain at least one valid line number configured on this device. All calling number information was corrected to be a valid line number before proceeding with call processing. Recommended Action Validate that the IP address from which the call was made matches the current IP address of the device. Please investigate that the endpoint is behaving as expected. For Cisco devices, reset the device and verify it is able to obtain the correct configuration file from TFTP; if the behavior persists, engage Cisco TAC as necessary.3rd party devices may trigger this Informational alarm if they do not send calling party information in the format expected by Communications Manager. This may also be indicative of a security issue in progress; proper investigation is highly recommended. 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 300/343
