I have also heard of not being able to hang up on some of these calls, which spells trouble if you happen to want to make emergency call at the very same time (it's happened!). But I am not sure who said what (if anything) about such junk calls. Re: call forwarding. I can still make outgoing calls, right? If I am making such an outgoing call and a call comes in, do I hear anything? (If the phone is on the hook, I hear one ring on an incoming call but cannot answer it there, right?) ------------------------------ Date: Fri, 30 Nov 84 17:24:19 est From: ulysses!smb@Berkeley (Steven Bellovin) To: MDIXON@su-score.ARPA, telecom@bbncca.ARPA Subject: phone wiring There are a number of common uses for the other two wires. The most likely use in this case is for the 'A-A1' lines -- an off-hook signal used by key phone systems to deal with someone picking up a held line, lighting the buttons to show a line is in use, etc. If that's the case, the answering machine should simply complete a circuit between those two when it's off-hook. ------------------------------ Date: Sat 1 Dec 84 13:19:49-EST From: Ralph W. Hyre Jr. <RALPHW@MIT-XX.ARPA> Subject: Automated recordings (dial out) To: telecom@BBNCCA.ARPA I suspect that activity of this sort will decrease when we all have those little boxes that tell us the number of the phone that is calling us. (They were testing them in Pennsylvania a year ago.) Then you at least have some information to give to the phone company when you report those harassing phone calls. You could even take it upon yourself to prevent them from harassing others by tying up THEIR dialout line with YOUR autodialer. - Ralph Hyre ------- ------------------------------ Date: 4 Dec 84 14:36:27 EST From: Gadi <FRIEDMAN@RUTGERS.ARPA> Subject: RE:Hello, I'm a computer To: telecom@BBNCCA.ARPA Getting an unlisted number might not help. When I was in high-school I worked for a Telephone Sales company (selling Newspapers). We were gived a card with the first 5 digits and had to dial the 100 last 2 digit combinations. This way we got all the unlisted numbers... -Gadi Friedman@Ru-Blue. ------- ------------------------------ End of TELECOM Digest ******************************
