Although I concur with the conclusions of most posting here, I think that some people are oversimplifying what happens when a telephone is hung up. A telephone isn't a light switch. It is somewhat more difficult to determine whether a telephone has actually gone on-hook (hung up) or not, especially from the other end of a connection. Jams herself has said, if I recall correctly, that this particular phone doesn't always hang up properly. Mrs. Dave and I have phones which periodically do not hang up properly.

It would take an expert in telephony to determine whether or not the telephone has actually gone on-hook. Fortunately, there are people who can determine these kinds of things by listening to recordings for clues. There are people who can tell you exactly what kind of switching circuit is being used, and so on. I think it would be interesting to request such an opinion. BPD should have done that, also --- and maybe they did. Wouldn't that be interesting? It may play a large part in a civil suit later on.

Sometimes I would swear that I hear a squelch circuit coming into play; other times I don't. It also appears to me that there is a change in the background noise as the phone appears to go on-hook; some of the ambient background noise disappears. There may also be a subtle change in the sidetone, but I can't hear it.

No one should assume that just because they heard a "click" that the phone is "off." However, I do agree that there isn't any evidence at all to the contrary and that the alleged conversations are just what was described by those who said that BPD was finding evidence to fit their theory, even to the point of lying and fabrication. I just point out that we need to be careful not to be inaccurate here in this forum, either. The point is: hearing a mere click is not enough, but there may be enough evidence on that tape that BPD should never have pursued this line at all.
