can i test two softphone desktop application

I need to test two softphone desktop application since it has call features , call transfer all these the phones should be installed only in seperate physical machines . how to test this type of scenarios using testcomplete.



For eg: If i dial A to B, B should be able to attend the call and cut the call after speaking.



Like these call features I need test, is it possible with testcomplete.



Please help me out,



Thanks in advance.
