I had an interesting situation at my house when I first moved in, I was pulling out some of the old rats nest phone and cable tv wiring and tapped onto the phonwe service with my butt set and what do I hear ? Someone's conversation that is definitely not in my house. I find the # and it is the old owners line that has been ported to their new address still connected to my house ! [Linked Image] So I guess if I had called 911 from that line and hung up the police would have responded to either my house or the former owners present address dependant on what the TELCO has in their database.
