TAPI : phonecall problem

[Yves84]

Hi all,

I have developped a phonecall functionnality for my PPC application. It works but I have an unpredictable problem.

First of all, some feature of my config: I am developping for Qtek 2020 and 9090 (both), with embedded Visual C++ (4.0 Sp4).

To make a phonecall, I used the following TAPI functions (like Microsoft Dialit sample):

- lineInitialize
- lineNegotiateAPIVersion
- lineGetDevCaps
- lineOpen
- lineMakeCall

and then (after conversation):

- lineGetCallStatus
- lineDrop (if needed)
- lineDeallocateCall
- lineClose
- lineShutdown

I am also using a callback function to manage line messages, info and states.

it can work correctly 20 times then crash or it can crash during the first call. Apparently the crash (application freezing) comes after lineMakeCall during line reply waiting.

Did you already heard anything about this kind of problem?

Please I need some help, it becomes very important and very urgent.

Best Regards
Yves
