CCM 4.1(2)-SR1 - Error: DeviceUnregistered - Device Unregistered

[p.abbeel]

Hi,

At random (can be any ip phone), I receive following message(s) within the event viewer; i read similar issues in the thread before but nobody presented a solution so far.

- All phones connect through PoE switches

- CCM's 4.1(2)-SR1's are connected at fixed 100FD.

Thanks for your help,

Peter

Do all your phones at that remote site register to one callmanager? If they all fail at the same time, it could be a CPU Utilization issue, Network issue, or callmanager crash on that server. Do you have a drwtsn32.log file for that server? Also, have you checked the NIC settings on that server? Upgrading the OS or upgrading callmanager will change this back to auto auto from 100 Full. I have seen that issue several times.

We're also having the same issue. Event viewer for CM 4.1(3)sr1, OS 2000.2.7sr5 shows about 20 phones at the remote office unregistering via device initiated reset. The phones all show 'Failback' under network statistics. NIC settings are at 100FD. If there are any more suggestions for troubleshooting, it would be appreciated. Thanks.
