Rejecting (hanging up) incoming call...

[Dmitry Smirnov]

Hello,

I have a call in Connected state (and passthrough mode). Using lineDrop() I
may go to Idle state and deallocate call then.
But how to really "hang up" the line? I mean that remote side user should
get BUSY signal. Is it possible?

Thanks in advance.

Dmitry.

As you mention passthrough mode, I assume you are using modem hardware
and the MS Unimodem TAPI Service Provider.

As far as I know you can't force a BUSY signal to the caller if you
have answered the call. All you can do is drop the call and the other
side should get a LINECALLSTATE_DISCONNECTED but it may take some time
for Unimodem to detect this (if that is what is running on the other
side.)

WriteFile(hPortHandle, "ATH\r", 4, ...)

If modem is in voice receive/transmit mode, you will need to send <h10><h03>
bytes before.
