Thank You for advise, but it's not the solution. I think that TAPI version 1.4 must work too. And I can't use lineInitializeEx(), because is's not supported in Win95 (it is written in MS Visual C++ help), so I must use lineInitialize(), where LINEINITIALIZEEXPARAMS is not used.

When you call lineInitializeEx() function to initialize the application's use of TAPI, it returns the number of line devices available to the application (lpdwNumDevs).

Device identifier values range from zero to one less than the number of devices present.

Not the solution you were looking for? Getting a personalized solution is easy.

Check your version of TAPI to see if it is 2.0 or later.

I am not sure what the difference is. I suggest checking each parameter you pass to lineInitializeEx() function to make sure they are correct, specially LPLINEINITIALIZEEXPARAMS lpLineInitializeExParams. Also, try higher version. You can download the latest version (2.1) from Microsoft web site.

OK. lineInitialize also returns the number of line devices.

There is an example code called 'dialit' on Microsoft web site. It may be helpful for you. (It uses lineInitialize function to do the initialization.)

dialit:
Uses the CTapiConnection class. It provides an easy way to initialize TAPI, connect, and make a voice-based telephone call.
