[cisco-voip] Call counters high on intercluster trunk

[Ryan Ratliff]

First make sure your CCM SDI and SDL traces cover 24 hours worth of  
data (on both clusters).  Next start monitoring the active calls  
counter at a time of day when you know there are no calls active.  If  
you see the counter increment from one data point to the next (say  
midnight Wednesday to midnight Thursday and there should be no calls  
active at this time) then you collect 24 hours of CCM traces from all  
servers on both clusters and open a TAC SR to have them analyzed for  
call leaks.

We have two UCM Clusters that are currently at 7.1.2.  The main one  
has most of the phones and the other has about 80 phones.  There are  
route patterns to the individual extensions that are on the 2nd  
cluster because the extensions overlap.  There is also a 2XXXX route  
pattern and PSTN access route patterns on the 2nd cluster that point  
to the main cluster.

The strange behavior is the longer the clusters are up the higher and  
higher the active call counters go.  After a few weeks we get about  
2000 active calls both clusters, and if we reboot a node on either  
cluster the calls in-between clear on both sides.

I cannot find any loops in the routing, the CSSs of the ICT on the 2nd  
server don’t allow access back to the main cluster.

Anyone have some ideas?

Thanks
