TAPI3, Dialed call with no answer. Next TAPI Operation Always Fails

I have a windows TAPI application that dials a call. If the call is
answered all is well, the call proceeds, and when the line goes onhook
my application is ready for the next call.

If no one answers the call, I disconnect and release the call. I wait
for the next program request to dial again. When the next call is
dialed, the TAPISVR goes nuts (100% CPU) and I get no dial tone and
the call is not dialed.
I get an INPROGRESS call state event, but with the TAPISVR hung, TAPI
never does setup of the modem nor dial the call.

I am doing async dialing. I have a TAPI event notification object and
a message pump for that objects events, connected to a separate thread
in my application.

I guess I am looking for a working sample program that does async
dialing using TAPI 3> I have gone through the usual sample program for
M$.

My environment

Windows7
MT5636ZPX Voice modem
Visual Studio 2k8
Application is C++

Andreas,

Sorry for being away for such a long time. I had to move my office
from NJ to Califormia which takes time.

I am having troubles with the TAPI browser. I get "LOAD TBL Failed"
running the browser on a Vista x64 system. I will try on my other

A simple answer to a question may solve my problem. If I make a call
(CreateCall and Connect) and the Connect fails, what is the proper
sequence of events to release the bad call. I do a call to Disconnect,
a call Release, followed by nullimg out the call object pointer to
free the object. Is this correct.

I will try to get a tapi browser log soon.

All help will be appreciated.

Mike,no probem.I get the same message on a Windows Server2008 64-bit OS.

Mike,

Did you do the ::Connect with fSync =0 or =1 ?
Anyway you don' t need to ::Disconnect() if the ::Connect() failed.
Or do you get any ITCallXxxEvents even when ::Connect() failed ?

Doing a ->Release() and =NULL on the ITBasicCallControl* should be fine.
The same for any ITCallXxxEvents that may have occured.

TB3x does not show this issue on a Windows Server 2003 64-bit OS.

I get the same message on a Windows Server 2008 32-bit OS too.
So at least regarding WS2008 it does not seem to be a question of x64 vs.
x86.
