"I'm going to try to add a feature to [glow]my[/glow] wardialer that allows it to play a sound file to the phone line."

It's mine...it's still being made actually.
Supports multiple modems for parallel scans on seperate phone lines, macro text for easy log entry, lots more! The interface should allow you to attach the phone line to a mic input, and a different one to turn the line on and off. I've already designed the one to turn the line on and off (will use the parallel port). Still need to make the one for the mic input. I'm trying to find a nice way to supress ring voltages (don't want 90v into your soundcard!). So far, all i've come up with is a zener for use as a voltage limiter.
