Windows Mobile 6 answer multiple calls

I develop a Windows Mobile 6 application where I have to manage multiple calls, using c++ TAPI (from C# using PInvoke).

The application works fine for a single call, but I do not know how to manage when I have an incoming call and I want to answer the second incoming call.

For example: I answer the first call with lineAnswer, I detect the second call and I want to accept it with lineAccept, then put the first call on hold lineHold and answer the second call with lineAnswer.

The problem is that I cannot manage at all the second call. What steps (function calls) should I follow to manage 2 incoming calls?

Solution

  • I found myself the solution:

    The command placed for the call is still lineAnswer but before, out application must be the owner of the call, so a I use lineSetCallPrivilege with the Owner value.
