Just wondered... There's been a lot of discussion on the methods used for signalling with the new Caller ID systems; naturally it all went in one ear and out the other. My question is this: would it be possible (not that I have any idea why I'd want to) to make a device which could mimic the signals sent from the CO such that when I called someone with a Caller ID box, once they answered, I could make numbers appear on their little screen? Or does the box ignore signals once a phone is off-hook? Or are the signals out of the bandwidth that would make it from my phone to their phone? Miguel_Cruz@ub.cc.umich.edu
