Using UCMA to connect to 3CX?

Has anyone used Microsoft's U开发者_StackOverflowCMA 2.0 SDK to connect to 3CX's free IP PBX to add voice capabilities to their application? If so, does it work? What I am trying to accomplish is having a windows form app running on 2 or more computers, and each person can connect to another person and carry on a voice conversation using their headset connected to their computer. App is in C# w/ .NET3.5 SP1.

UCMA 2.0 is only for Server Based Application and does not support to create client applications.
