Actually, I was thinking this: There's a WiFi repeater in close proximity to the phone lines. Of course, it also has a small wall-wart type switching power supply. I was wondering how possible it might be that some kind of interference from the repeater or it's power supply might be taking the line off hook externally, then somehow pulse-dialing 911. That seems to me almost statistically impossible, let alone to do it 3 times in a 36 hr period. But if the switcher pulsed regularly at the right frequency...? Mark Robert Rolf wrote: > Solenoid.
