7975 won't stay registered

I have 3 7975 series phones attached to a 3750 running advipservicesk9 12.2(44)SE6 providing PoE. They register to UCM running 7.1.2.10000-16. The configuration of the phones on UCM is pretty straight forward nothing fancy. The problem I am experiencing is the phones will continually register and unregister with the call manager. I can maintain a constant ping to all 3 phones throughout this process. I see no errors on any of the physical interfaces or the Tunnel interface. The 3750 connects to a 2811 with an IPSEC over GRE tunnel back to our main location. The tunnel is up solid as I said I can maintain a constant ping to all 3 phones whether they are registered or not. I can also web into the phones while they are registered.

Re: 7975 won't stay registered

Hi Rick,

To start with we can check the application logs from the call manager server to which the 7975 is registered and we will see a device unregister event with a certain reason code.

for DeviceUnregistered Alarm
        Unknown = 1,
        NoEntryInDatabase = 2,
        DatabaseConfigurationError = 3,
        DeviceNameUnresolveable = 4,
        MaxDevRegExceeded = 5,
        ConnectivityError = 6,
        InitializationError = 7,
        DeviceInitiatedReset = 8,
        CallManagerReset = 9,
        DeviceUnregistered = 10,
        MalformedRegisterMsg = 11,
        SCCPDeviceThrottling = 12,
        KeepAliveTimeout = 13,
        ConfigurationMismatch = 14,
        CallManagerRestart = 15,
        DuplicateRegistration = 16

Once we have this information we can start moving in a certain direction.
