Hi Serkan,
According to the UCCX compatiability, it is not supported.
http://www.cisco.com/en/US/docs/voice_ip_comm/cust_contact/contact_center/crs/express_compatibility/matrix/crscomtx.pdf
That means the JTAPI clinet verion has not been tested. It is usually the n, and (n-1)th version of the CUCM are compatiable with the nth version of UCCX.
In your case, if you will be using for AA functionality, you may give a try of integrating, it may or may not work. If it dosn't work, TAC will definitely not support it because of incompatiability.
Hope it helps.
Anand
