If its that critical cellular is the only way to go. You can also use this on T1 lines to receive from pstn lines. So it's not VoIP. Sent from my iPhone On Apr 29, 2013, at 1:15 PM, Steven Schoch <schoch+freeswitch.org@xwin32.com> wrote:
Speaking of alarm systems over VoIP, here's a story of an alarm company that was sued by the estate of a murdered woman because her alarm system failed to notify the central station when the attacker broke in. It turns out she had switched to VoIP a few weeks earlier, which caused problems: http://www.security.honeywell.com/hsc/documents/alarmorg_VoIP.pdf
Here's something from an alarm company: http://www.thealarmcompany.com/files/voip%281%29.pdf And from another alarm company: http://bentleyalarm.com/why-voip-is-bad-for-your-alarm-system/
Bottom line: I'd think really hard before switching an alarm system to VoIP. When we switched the company to VoIP, I was able to get a very inexpensive measured line for our alarm system. (We also use it for incoming FAX, because it works.)
