I think I'm that guy!
Yeah so you'll still need a voltage inducer, although I've done a lot of testing and now know the right setup to get an inducer to work on PAL modems by doubling the voltage (2 9v batteries in series).
I have a script running on my Pi which automatically answers the call. I've tested this on PSO and it works great.
Before I upload an image I need to get the script detecting hang up, and starting on boot. Unfortunately real life is getting in the way ATM but I'll do this ASAP! I'll dedicate a website to this when I'm done so everyone can get online
