H323

Mar 3, 2015 at 9:53 PM
Hello.
I am trying to transfer calls with ITAPI3, after much research i found that unimodem does not support transfer call, and also it is for half-duplex devices. So i decided to use h323 tsp as my service provider. I want know is it possible?
Also i cant find H323.tsp in my windows 7, whats problem? from where i can get it?
Its so urgent.

thank you!
