Phonecall came in just before 10:30pm. No message. What a bunch of jack***es.

(418) 683-3634 Is the number for the outgoing line at protectron / security 24 .Since those line are for outgoing call only that why you cant call back at the number .

(418) 683-3634 is, as already reported, for Protectron Security. I received a call from that number late at night. I have a friend who has a Protectron system in her home and they were trying to get hold of her because they were getting a low battery alarm. I am one of her emergency backup numbers. No problem. It's not a sales call.
