" You could also build simple phones from carbon mics, simple earpieces
" and batteries. Add a switchboard for routing, then maybe add a strowger
" and dials. The facinating thing about the phone system is that the first
" phones with dials (early 1930's) are still supported. That is why you
" can dial the operator by pressing the switch-hook 10 times quickly.
yup, and they even still charge extra for touch-tone svc. check your
line charges...
