- There are auto-dialers available that prevent this. I tried this
- trick with the elevator phone in our building. When you take the
- phone off-hook, you hear dialtone, then hear it dial the answering
- service for the elevator company. As soon as the dialer hears a
- touchtone generated from the headset, it hangs up the line. Boy, they
- won't let anybody have any phun these days!

- [Moderator's Note: Now that is interesting! I wonder how they do it?
- Apparently if the autodialer hears a tone, and *it* did not make the
- tone, it disconnects. Is that how it works? PAT]
