serial port, modem, audio files through modem

[Stephen Barncard]

Your roadblock to doing this is not Rev, but interface hardware. 
Modem interfaces just can't send back audio in all cases I've seen. 
You need something more like an telephone hybrid.

If this is a professional installation, I'd suggest finding an 
interface that is designed for the purpose, especially if the audio 
is to sound fairly decent. Most modems are designed to listen to 
audio only before connect, and not receive audio outside of the usual 
mod/demod it does. Rat Shack crap will not really work well, trust me.

I'd search around in the telemarketing and broadcast hardware world 
for this. Somebody must make a telephone interface. Find something 
that uses a serial interface; proprietary USB hookups may not work 
with your app.

Here's some of the best interfaces I've seen:

you might contact them and ask for what you need.
