I told him, "When we hang up, get back on and dial 211-2345. That’ll give you an automated announcement of the number of the phone you’re using. Then call me back collect and tell me the number." When I had the number, the next step involved manipulating one of the phone company switches. From my computer I dialed into the appropriate switch and changed the "line class code" on that phone to the code for a home telephone, which would allow incoming and outgoing calls. While I was at it, I added three-way calling and call-waiting. And I programmed the phone so all the charges would go on the bill of LAPD’s Van Nuys station.
