[comp.dcom.telecom] Wrong Numbers With Nobody There

msb@sq.sq.com (Mark Brader) (10/05/89)

I sometimes experience a different form of "Wrong Number With Nobody
Talking".  The phone will ring and I will pick it up on about the third
ring, only to get immediate dial tone.  Nobody who places genuine calls
to my house gives up that fast, so it's not someone abandoning the call
just as I pick up the tone.  There's no period of silence at the other
end, so it's not a modem/FAX call.  Not even a short period of silence,
as one would expect with "a burglar calling to see if anyone is home".

Could this be some sort of phenomonen originating at the switch?
I'm in area code 416, prefix 488; Bell Canada evidently has a relatively
modern switch there, as things like Call Waiting and Three-Way Calling
are available.  When I call another number within 488, the ringback
usually comes instantly as I let go of the 7th pushbutton.  But I don't
know what model it actually is.

By the way, *do* burglars phone houses to see if anyone is home?
