What's Happening to Landlines
Phone companies are retiring the old copper phone network because almost nobody uses it anymore and it costs a fortune to maintain. This isn't a rumor or a someday thing. AT&T stopped taking new landline orders in much of the country in late 2025, started permanently shutting down the equipment behind them in mid 2026, and plans to have nearly all of it retired by 2029. When your area's turn comes, you may get as little as 90 days' notice. Here in California there's a court fight over how fast it can happen, but the direction isn't in question. The lines are going away.
Why Your Alarm Cares More Than Your Phone Does
Losing a landline phone is annoying. Losing the landline your alarm dials out on is invisible. The panel on the wall still looks alive. It still arms, still beeps, still turns on the little lights. The part that dies is the phone call to the monitoring center, and nothing on the panel tells you it's gone. Businesses in this situation find out one of two ways: their alarm company notices the signal stopped, or something happens and nobody comes. The same goes for fire panels, which are often required by code to have a working connection, so a dead line isn't just a security gap, it can be a code and insurance problem.
How to Tell If Your Alarm Uses a Landline
You don't need to be technical. Any of these is a strong clue:
Your system was installed more than five or six years ago and hasn't been upgraded since
There's a phone wire running into your alarm panel
Your phone bill still includes a "business line" or "analog line" you can't explain
Your monitoring bill mentions a phone line
The fastest check of all: call your monitoring company and ask two questions. How does my system communicate, and when did you last receive a signal from it? If the answers are "phone line" and a long pause, keep reading.
The Fix Is Smaller Than You'd Think
You almost never need a new alarm system. The usual fix is a cellular communicator, a small device added to your existing panel that sends signals over the cell network instead of a phone line, the same way your phone works without a wire. It's a modest upgrade, not a rip-out. And it's actually an improvement over what you had: cellular communicators check in with the monitoring center regularly, so if the connection ever dies, somebody knows within hours instead of never. Internet-connected panels solve the landline problem too, and the strongest setups use cellular as the path or the backup, since the internet tends to go out at the same time the power does.
Don't Wait for the 90-Day Letter
When a region's shutdown date lands, every business with an old panel calls their alarm company in the same month. Getting ahead of it means picking a convenient week for a small upgrade. Waiting means joining a rush with a deadline.
