Event Viewer Errors: DeviceTransientConnection - Transient Connection attem

Error: deviceTransientConnection-TransientConnection attempt.

Connecting Port:2427

Reason Code :2

App ID: Cisco CallManager

Explanatio: A connection was established and immediately dropped before completing registration

Does anyone know what this means and how I can fix it. Messages appear on both call manger event logs

Please help, thanks in advance


Re: Event Viewer Errors: DeviceTransientConnection - Transient C

The error means a device, a MGCP gateway in this case based on the port # (2427) is not able to register to call manager. It will try one server then each other it's configured for so you will see errors on each server.

The reason code 2 means NoEntryInDatabase. Is this MGCP gateway configured in call manager and if so, does the domain in call manager config MATCH that on the gateway? The domain names must match.

On the gateway, you csn do a 'show ccm-manager' and on the first line it will list the MGCP domain name. This is a combination of the routers hostname and domain name. If you changed a routers hostname or added/changed domain name command then this may have broken this.

The full event log was not posted, but the full entry will have IP and/or hostname of router that router is trying to use so you can track it down and check it's config.
