Alarmreceiver is an Asterisk application for the security industry. From the description of the module, "This application emulates an SIA (Ademco) Contact ID alarm receiver. The Contact ID protocol is the most popular signalling protocol used between alarm panels and central stations." In a nutshell, an alarm panel calls an phone number connected to the switch. The switch answers and waits for a series of DTMF tones. The switch and panel communicate by exchanging tones. The panel closes the connection and the switch takes action. From what I've been able to understand, the switch records the event in a file. From my perusal of the FS documentation I believe this same functionality can be performed by a FS module but since I haven't actually written modules I'm obviously not aware of the limitations. So my question is, "is this something that can actually be done?" Thanks, Jim.
