Error: DeviceTransientConnection - Transient connection attempt

Question

Hello experts,
I have recently inherited a small CCM system (a publisher, no subscribers, one mgcp gateway)
For the most part everything seems to works ok, however, every couple of weeks we cannot place external calls (reorder tone), although we can receive incoming pstn calls. Internal calls work fine. I temporarily fix this problem by resetting the gateway. I have found nothing in the gateway logs or debug sessions that indicate a problem.
However, every forty seconds exactly, for weeks on end, and across reboots, I get the following event message:
Event Type: Error
Event Source: Cisco CallManager
Event Category: None
Event ID: 3
Date: 10/9/2006
Time: 4:56:23 PM
User: N/A
Computer: HQCCM1
Description:
Error: DeviceTransientConnection - Transient connection attempt.
Connecting Port: 0
Device name [Optional].:
Device IP address.: 192.168.253.1
Device type. [Optional]: 255
Reason Code [Optional].: 6
App ID: Cisco CallManager
Cluster ID: StandAloneCluster
Node ID: 192.168.1.6
Explanation: A connection was established and immediately dropped before completing registration. Incomplete registration may indicate a device is rehoming in the middle of registration. The alarm could also indicate a device misconfiguration, database error, or an illegal/unknown device trying to attempt a connection.
Recommended Action: No action is required if this event was issued as a result of a normal device rehome..
What device is causing this? As a troubleshooting I went and eliminated every mtp, transcoder, and conference service we had and the error message continued. I only have one pri on the gateway.
Any ideas?

Do you know what device has IP address 192.168.253.1?
What type of gateway and what IOS version are you using? There have been some DSP problems with certain versions of IOS that could cause the problem you are having. The link below references one such problem.
