Suggestion for box where alarm monitoring failovers from landline to cell phone - when landline is cut.
All, I have a standard slomins alarm system, wired that connects to the CS via POTS. I'd like to add one a cell phone connection that in the even the land line is cut, would allow the alarm to dial the service. Any suggestions on a box to use?
TIA John
