If you dial an exclamation point (!) I think it will cause the phone to go on-hook for 1/2 second then back off hook.

>> 1. Create a conference call...
You should look at the TAPI functions.  There is one called lineSetupConference() that looks worth investigating.  

>>2. Forward the incoming call to
What about lineFOrward() API function?

I think you are wanting to monitor for a FLASH signal from the phone.  That comes in like any other button as a PHONE_BUTTON message in your tapi callback.

what I need is to create flash signal on an open line that I collect before.
My app. is a desktop win32 program that simulate phone instrument and record the activity of the operator. I need to limited the flash button that there is at any phone system.

As i know, you wish to hang up incomming call and watch
again for new ringing? If so, use:
lineDeallocateCall(hCurCallstatehCall);
where hCurCallstatehCall is HCALL you obtain during
processing
case LINE_CALLSTATE:
   hCurCallstatehCall=(HCALL)hDevice;
.....

If you have answered by lineAnswer(), than must call lineDrop().
Depending of what OS you are using, there may need to
close line and reinitialize line (in Windows95 there
are errors in TAPI interface, about other MS OS - i don,t know).

As I understood the 'Flash' button on the telephone device create a disconnecting for short time on the line.
The main reason I need it is for:
1. Create a conference call between incoming call to the system and another extension.
2. Forward the incoming call to another extension.
