[cisco-voip] CCM Trace setup

[Wes Sisk]

Hi Michael,

Trace error is not very useful for this type of issue.  Detailed will 
show all messages and then q931translator.exe will help you parse the 
h323 messages between the clusters out of the traces.  After that 
notepad is your friend :)

As for the ICT not working and then trace configuration not taking 
effect; both these could be symptoms of change notification being 
broken.  change notification (cn)  is what causes the changes you make 
in /ccmadmin to affect the real-time running ccm.exe process.  If cn 
really is broken, there are 2 steps to get it back:
1. restart the cisco database layer monitor service - no process to call 
processing.  Then go and click "update" on your route pattern and newly 
created trunk.  This will re-send the message to CM to insert these real 
time.  If it still does not work goto #2
2. restart cisco database layer monitor and ccm.exe.  CCM.exe is 
responsible for initiating the connection to database layer monitor and 
tell dblm "i am interested in these updates".  In this case, when 
ccm.exe starts up, it will read the new device and route patter directly 
out of the database so cn is not involved at all.  If it still does not 
work, then the problem is the configuration.

For ICT configuratoin, keep in mind that all servers in cluster1 need to 
know about all servers in cluster2.  In the Trunk config page make sure 
to define as many call processing servers in the remote cluster as 
possible.  Then do the same on the remote cluster.  This how ccm.exe 
matches the incoming h323/h225 call setup message:  Match the source IP 
to the IP of a device, then use the CSS of that device to determine what 
destinations with in the cluster that calling device is allowed to reach.
