I just installed 3cx phone for Windows v12 for the RC. I have all the new presence information and seems to be working well. I noticed that it wanted to install it in the ProgramData directory not Program Files and I tried it in both but have the same problem. If I type in a number and hit CALL, or double click another extension, or type it in the presence full screen, the call does not go through. Nothing happens and 3cx phone system does not seem to be getting the messages. The phone is in CTI mode. Any ideas?
