/mcpdevice will re-register automatically once the TCP connection is established. Error Message %UC_CALLMANAGER-6-StationAlarm: %[Protocol=String][TCPPid=String][DeviceText=String] [Param1=UInt][Param2=UInt][AppID=String][ClusterID=String][NodeID=String]: A station has sent an alarm to Unified CM for pass-through purposes. Explanation A station device sent an alarm to Unified CM, which acts as a conduit from the device to generate this alarm Recommended Action To determine the appropriate action, refer to the specific device type and information passed from the device via this alarm Error Message %UC_CALLMANAGER-4-StationEventAlert: %[Protocol=String][TCPPid=String][DeviceText=String] [Param1=UInt][Param2=UInt][AppID=String][ClusterID=String][NodeID=String]: A station sent an alert to Unified CM for pass-through purposes. Explanation A station device sent an alert to Unified CM, which acts as a conduit from the device to generate this alarm Recommended Action To determine the appropriate action, refer to the specific device type and information passed from the device via this alarm Error Message %UC_CALLMANAGER-5-MGCPGatewayGainedComm: %[DeviceName=String][AppID=String] [ClusterID=String][NodeID=String]: MGCP communication to the gateway has been established. Explanation The MGCP gateway has established communication with Unified CM Recommended Action Notification purposes only; no action is required Error Message %UC_CALLMANAGER-2-MGCPGatewayLostComm: %[DeviceName=String][AppID=String] [ClusterID=String][NodeID=String]: MGCP gateway has lost communication with Unified CM. Explanation The MGCP gateway is no longer in communication with Unified CM. This could occur because Unified CM received an MGCP unregister signal from the gateway such as RSIP graceful/forced; Unified CM didn't receive the MGCP KeepAlive signal from the gateway; the MGCP gateway didn't response to an MGCP command sent by Unified CM three times; a speed and duplex mismatch exists on the Ethernet port between Unified CM and the MGCP gateway; or the gateway has reset. Recommended Action Reset the MGCP gateway in an attempt to restore communication with Unified CM; check the speed and duplex settings on the Ethernet port. In the case of an unwanted reset of the gateway which caused communication to be lost, take precautions to ensure that no unauthorized personnel resets the gateway from Cisco Unified CM Administration or via the gateway terminal. 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 247/343
