/mcpload ID configured on the Phone Configuration page, verify that the firmware load ID exists on the TFTP server (on Cisco Unified OS Administration page, access Software Upgrades > TFTP File Management, then look for the file name as specified by load ID). 23 DatabaseTimeout - Unified CM requested device configuration data from the database but did not receive a response within 10 minutes. 25 RegistrationSequenceError - (SCCP only) A device requested configuration information from Unified CM at an unexpected time and Unified CM had not yet obtained the requested information. The device will automatically attempt to register again. If this alarm occurs again, manually reset the device. If this alarm continues to occur after the manual reset, there may be an internal firmware error. Collect existing SDI and SDL traces and contact the Cisco Technical Assistance Center (TAC). 26 InvalidCapabilities - (SCCP only) Unified CM detected an error in the media capabilities reported in the StationCapabilitiesRes message by the device during registration. The device will automatically attempt to register again. If this alarm occurs again, manually reset the device. If this alarm continues to occur after the manual reset, there may be a protocol error. Collect existing SDI and SDL traces and contact the Cisco Technical Assistance Center (TAC). 27 CapabilityResponseTimeout - (SCCP only) Unified CM timed out while waiting for the device to respond to a request to report its media capabilities. Possible causes include device power outage, network power outage, network configuration error, network delay, packet drops, and packet corruption. It is also possible to get this error if the Unified CM node is experiencing high CPU usage. Verify that the device is powered up and operating, verify that network connectivity exists between the device and Unified CM, and verify that the CPU utilization is in the safe range (you can monitor this via the CPU Pegging Alert in RTMT). 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 166/343
