Hi to all.
I develeoped an application that monitor and control phones and CTI Portti implement a Telephone Console.
My test plant is based on CUCM<strong style="font-family: Arial, Helvetica, sans-serif; font-size: 11px;"> 8.5.1.10000-26, on a single server. 
In production, my client has a CUCM 8.6.2.20000 in cluster. In test environment it works fine.
In production environment I found a bug that invalidates all my work: CiscoTerminal.getDeviceState() does not return current terminal status, it always says Idle State  despite there are calls in progress.
I found the following bug: http://tools.cisco.com/Support/BugToolKit/search/getBugDetails.do?method=fetchBugDetails&bugId=CSCtu92322
It seems my problem. Anyone else has had the same problem ? I have to update the CUCM ?  My client is not happy to install a new version, but if it is the only solution I'll do it.
 
 
 

Thanks for your response.
My client has upgraded the CUCM with 8.6.2.21900-5 version. 
The bug seems to be resolved, but there is still an error:
With IPPhones it works well, but with CTI Ports it works only after a reset of the device, that is: when we restart our server and after we have registered the CTI Ports, the getDeviceState() still does not returnj the current terminal status. We have to reset all CTI Ports (manually) to get the right device Status.
This is a problem, because we have 3 nodes in cluster for our server that controls CTI ports one at a time and we can't reset CTI Ports after only one node have to be restarted.
 
Any idea ? We are thinkling to open a case with CDN, but my client is waiting for an answer as soon as possible,
Thanks.

JTapi version matches with UCM version. The problem with CTI Ports still remains.
We have found a  workaround to resolve this (we find some calls on the DN), so we don't use getDeviceState no more.

I am currently out of town and will be back to HK on 18/11. My response will be delayed due to limited internet access and timezone difference. Please drop me an email for any issues or call me for any urgency.
