/mcp28 SecurityMismatch - Unified CM detected a mismatch in the security settings of the device and/or Unified CM. This alarm can occur due to any of the following situations: The device established a secure connection yet reported that it does not have the ability to do authenticated signaling; the device did not establish a secure connection but the security mode configured for the device indicates that it should have done so; or the device established a secure connection but the security mode configured for the device indicates that it should not have done so. To correct the error, ensure that the security settings of the device and Unified CM are correct for your deployment. Resetting the device may help because it forces the device to download its latest settings. If the device is a Cisco phone, verify that the TFTP service is running and reachable by the phone and view the Unified CM Database Status report in Cisco Unified Reporting to verify that database replication is Good. You can also issue the following command on the CLI to view database replication: utils dbreplication runtimestate. 29 AutoRegisterDBError - Auto-registration of a device failed because auto-registration is not allowed for the device type or because an error occurred while adding the auto-registering device to the database (stored procedure). Note that if Unified CM is in mixed mode (System > Enterprise Parameters > Cluster Security Mode = 1), auto- registration is not allowed and the device must be configured manually. If you are not planning to auto-register phones, either manually configure the phone (Device > Phone > Add New), power the device down, or remove it from the network. If you are attempting to auto-register this phone, verify that the cluster is not in mixed mode (System > Enterprise Parameters > Cluster Security Mode =
Cisco Unified CM > ensure that the Auto- registration Disabled... checkbox is not checked). 30 DBAccessError - Device registration failed because of an error that occurred while building 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 167/343
