TAPI modem questions

I want to build an automated telephone response system, where people can call me, my modem picks up, plays a welcome message, waits for a touch tone response then says something back to the caller. Basically the same kind of system you get when calling a big company. I envision having 4 modems/4 phone line installed at once to receive calls.

I need some advice. Is this possible in VB? What problems might I expect? What modems should I purchase? What works best? I have done some work with VB and modems in the past and I remember having problems with some hardware being partially unsupported.

I did read some other threads on the topic and TAPI seems a bit complicated. Does anyone know of a 3rd party software or hardware component I can purchase to simplify things?

Thanks for any and all advice.

See my reply in the thread Phone Call Recorder.

If that is the one or one of the ones you are refering to as a bit complicated then OK, forget it.
