It's two fold. First is the obvious of conducting a call/receiving the caller id info. The second is to send directly to the phone, and transmit the caller id data. By flow through, I mean that the phone has one of 2 states(on the hook, off the hook), and three sub states(on the hook/off the hook in use/off the hook not in use). On the actual phone we pick up the receiver, or press the button on the cordless to receive, but the line is always connected, meaning it stops at the phone(terminal). I pick up the receiver, and transmit a series of specific tones which indicate the area code, trunk number and extension(if I remember this correctly, it's been a while since I studied the phone itself). So I have to receive the signal that the phone is ringing(then I'm assuming it sends the caller id info in between rings in some form)/or transmit a series of tones to them to connect. So I think my main question is what modules might be relevant to doing this? And should I be thinking of it any differently than a USB port which has 4 pins two data(+-), and two dc current(+-)? _______________________________________________ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: http://mail.python.org/mailman/listinfo/tutor
