Someone has to have experienced this problem. I have now installed CAD on every agents PC. I tested after every install with a call to my cell and I was able to monitor it. The next day, monitoring real calls, only about 1/3 of them were working. I've been through countless calls with TAC to get as far as I've gotten now. Span to PC port is enabled in UCM and on the phone it's listed as such. Postinstall.exe is pointed to the correct address on the NIC. I'm out of options and out of my mind. Anyone?
