Windows Mobile 6 answer multiple calls

Question

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?

Have you looked at the OpenNetCF.Telephony library? It's an open source C# wrapper around the TAPI functions, and it comes with a number of samples that show how to monitor and answer incoming calls. Maybe there are some pointers for you in there on how to handle your specific scenario.

I am currently using this library, but it provides me only lineAnswer option. I added myselt lineAccept but it still doesn't work. – Alina Danila Jun 01 '11 at 11:40
What are you sending in the `lpsUserUserInfo` parameter of your lineAccept function? – Tom van Enckevort Jun 01 '11 at 11:50
I'm sending a NULL pointer. Do you thimk that it matters? I shall make some more debugging to see what is the retirn code for lineAccept. Thanks. – Alina Danila Jun 01 '11 at 12:02

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.
