[cisco-voip] Transient Connections

[Kevin Thorngren]

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.
