TCPucmClosedConnection - The Cisco Unified Communication Manager closed the TCP connection
Reason 14 : MalformedRegisterMsg - (SIP only) A SIP REGISTER message could
not be processed because of an illegal format. Possible causes include a
missing Call-ID header, a missing AoR in the To header, or an expires value
that is too small. Check the REGISTER message for any of these issues and if
you find one, correct the issue.
Configuration Mismatch (SIP only) The configuration on the device does not
match the configuration in Unified CM. This can be caused by database
replication errors or other internal Unified CM communication errors.
First go to the Cisco Unified Reporting web page,
Generate a Unified CM Database Status report
verify "all servers have a good replication status".
You can also go to the Real-Time Reporting Tool (RTMT) and check the Replication
Status in the Database Summary page. If status shows 2, then replication is
working. If this device continues to unregister with this reason code, go to
the Device Configuration page in Unified CM Administration for the device
identified in this alarm and click Save. This generates a change
notification message to the Cisco CallManager and TFTP services and rebuilds
a new configuration file. If the problem still persists, restart the TFTP
service and Cisco CallManager service.
