Pioneer Telephone MuseumI used to write software for a company that makes telephone switches in north Phoenix.
3640 E Indian School Road
Phoenix, AZ
Also I used to subscribe to 2600 Magazine which is called the Journal of the American Hacker and used to have a lot of interesting articles on telephones. Another good magazine on the subject is Blackedlisted 911, which is out of Orange County California.
It's also a magazine for hackers. And despite the fact that 2600 went downhill, the last time I read it Blackedlisted 911 still had a lot of good technical articles in it.
I found this in an article by Larry Cox.
