TAPI & PPC : phonecall problem

[Yves Caudron]

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,
If you post the same message to several newsgoups don't multi-post (send it
several times) but cross-post (send it one time with all the newsgroups
separated by comma) it.

It is recommended to post TAPI questions only to the managed TAPI newsgroup:
microsoft.public.win32.programmer.tapi
See my TAPI and TSPI FAQ:
