Hi i am looking at getting a  1970' telephone to put in my tardis but was wondering how i go about wiring and powering one up so that i can get it to ring and then once receiver is picked up it plays a sound  and once the receiver is put down it stops the sound playing Thank you also does anyone have photos of the correct phone style to use Thank you

This tutorial over at Instructables should help I think: http://www.instructables.com/id/Raspberry-Pi-in-Rotary-Phone/

Its something I plan to do as well, but I've broken the rotary part of m'phone so that's yet another job to do!
