Windows Telephony service Stops
Akil Dsouza
Hi Andreas,
The windows telephony service gets stopped automatically after some time of
debugging my TSP. But no errors/error messages during Debugging.
How to debug this problem inside the TSP, that causes the windows telephony
service to stop.
I am using VC++ 2008 for debugging my TSP by attaching it to TAPISRV(Attact
to TAPISRV plug in to VS-2008)
Regards,
Akil

Akil,
was there still a TAPI application active, i.e.TAPI was initialitzed, at
that time?
Was the TAPISRV process stopped in the debugger (by a breakpoint) or were
you manually stepping through the code or was it running normally in the
debugger?
Bachground for my questions: when TAPI isn't initialized by any TAPI app
anymore, i.e. lineShutdown by all apps, then TAPISRV stopps itself after
about 30 seconds.
This would neither be a TSP nor TAPISRV issue - it's by design of TAPISRV.

No, There were no TAPI applications active. I was running the TSP with
Debugger(Attached to TAPISRV). When I closed phone.exe the Debugger was
still running
But after say 1- minute debugging get stopped, and when I checked the
Windows Telephony Service, it was stopped. If this is a behaviour by design
then I have no issues.
That means, the windows telephony service gets restarted again when the
phone.exe is opened again?

Akil,
exactly, this is by design.

Yes, but...
presumably in another process, so your attached debugger doesn't get it.
I suggest to simply leave ony TAPI app constantly have TAPI initialized,
except you are debugging TSPI_providerInt() / TSPI_providerShutdown()
issues.
For those case a DebugBreak() in TSPI_providerEnumDevices() may help.
Or launching TAPISRV in the debugger may be a solution.
