I got a spate of them recently but then they stopped. I'm usually at work during the day but when I'm home a lot of crap comes in over the phone.
Sometimes hangup calls like that are from a fax machine on repeat-try.
When I've had them, I put on a fax machine on the line and gotten a legitimate fax sent to my number in error. (Since it's cumbersome for me to rearrange the wiring I don't do it often.)
Other people who have had them complained to the phone company, and the phone company reported back it was an errant fax machine. I think the volume of such calls is so high today the phone company won't bother anymore.
However, I suspect many of these are "spam" faxes going through all numbers searching for a fax machine to tell you about stock or land opportunities. Of course it could be an automatic dialer gone bad, just dialing up everyone over and over again. Just because someone owns such a unit and has an outward WATS line is no guarantee they know what they're doing.
[TELECOM Digest Editor's Note: I have a fax machine on one of my internal extensions; the computer modems (which by default do not auto-answer) and the fax machine (which can be set to auto-answer) share extension 105. If someone wants to send a fax they ask me (or whomever) to be transferred to extension 105, or if I answer the phone and hear the familiar beep sounds, I just flash and dial 105 then disconnect myself. My problem here is that 773-828-4212 is somewhere (only god knows) in Chicago; the voicemail picks it up before any human (even if I knew where it was and had a human assigned to pick up on it) can get to it.Your suggestion would work for me if "Ms. T. Bernard" (see another message in this issue) was calling direct into my Kansas number. Maybe I should praise God she has not yet gotten around to calling into the
630 area. PAT]
