Telephony programming

While I’m online using my modemn, my phone line is busy. If there is a phone call coming, I have no way of knowing it, hence can’t pick up the phone. I’d like to write a C/C++ program running in the background of my PC. It’s capable of detecting an incoming call and shutting down my modemn at appropriate time so I’m able to take the call.

Any ideas ?

Actually I don't think it is possible.  At least without going deep into device driver programming. BUT ( there is always a but ) there is a new standard for modem communication called V92 ( if I am not mistaken).  It does several extra things over V90, which would be most available standard.

Among other thing, it provides capability you are looking for.  Modems compatible with V92 are available in stores, but before you run and buy one you need to check with your ISP if they support it on the phone line you are using to connect.

I know it probably not going to help much right now, but in a future most ISPs will swith to V92.  At least that is the hope. :-(
