[cisco-voip] Transient Connections

[Ryan Ratliff]

Additionally, you can look up the Reason Code at http://www.cisco.com/ 
univercd/cc/td/doc/product/voice/c_callmg/4_1/alarms41.htm.

In this case 6 means "ConnectivityError" which is pretty generic.   
Most often these are seen in the failover/failback situation Kevin  
described.

These errors are caused when a device starts registering with CCM  
then closes the TCP connection during the registration process.  The  
transient connection is not a problem, in and of itself.  But it is  
normally a result of a device unregistering from it's primary CCM and  
starting the registration process to the secondary.  During this time  
it will attempt to reconnect to the primary CCM.  If it does it will  
stop the registration process on the secondary and start registering  
with the primary.  Investigation as to why the device unregistered  
might be needed if it wasn't purposely done via CCMAdmin or other means.

There could also be other reasons for this message which are  
indicated in the text below.

Unless you are certain that the device with IP 192.18.88.52 was  
purposely unregistered at the time of this event then you might want  
to investigate why it is trying to register with this server.
