- Yes, this is exactly what it does. The reason I was trying to dial
- out is that I was calling the ANAC number to get the elevator's phone
- number. Then, I was going to call it when co-workers were in it to
- conduct the 'elevator survey' that was talked about here a couple of
- years ago. But, I suspect that if the auto-dialer is smart enough to
- prevent me manually dialing with a pocket dialer, that it probably
- blocks incoming calls from reaching the phone as well.

- [Moderator's Note: I've seen elevators with autodialers on their
- phones but quite a few have a direct ring-down circuit instead. That
- is, you take it off hook and it immediatly starts ringing the other
- end of the dedicated wire. In the 77 West Washington Building
- downtown, (Chicago Temple Building) each elevator has a ring-down
- phone which rings to the elevator supervisor in the lobby on a
- multi-line phone with several buttons. Going off hook in the elevator
- lights a button on his phone; if he goes off hook it rings the
- elevator phone associated with that line/button. There is an
- 'extension' phone with many buttons in the elevator machine room on
- the 21st floor so the building engineer or elevator mechanic can also
- talk to people in each car. The lobby supervisor can talk to the 21st
- floor via the building's PBX system. He also has an illuminated panel
- which tells him where each car happens to be in the shaft at that
- moment and if it is moving or sitting there, etc. PAT]
