i put a question in the general forum asking what system, hardware or software based is capable of this function.
playing with the phone systems is just a hobby and trying to learn how they work and do what they do.
it's how i taught my self radios and computers.
i barely graduated high school, but managed to learn how to build repair and use computers, and radios, and taught myself basic electricity and electronics.
I spend enough time messing with them, i'll get it figured out

there is no purpose to the phone system stuff for me other then experimentation, but the question i put in the general forum has a practical use that i would like to implement on my home phone.
i know these are 10-15 y/o systems, but you learn by tinkering with the old stuff and working your way up

want to thank all the forum members for their patience.
