we have UCM 7.1(2), CuciMoc 7.1.3 and OCS R2. After some effort, we are able to get these clients to work on Windows 7, 64bit. Yes, I do understand that Cisco does not officially support Windows 7, 32 or 64 bit yet, but I am not sure this is an client OS issue.
when placing internal calls, caller ID is working both ways. However, if an external call comes in, and the client does not already have that number in the contact list in OCS, we get an "unknown number". when calling the deskphone, caller id shows up properly.
I didnt setup the OCS server, or install the CSF, setup dialing rules, etc, so I am kind of flying blind.
Any tips/pointers would be appritiated!
