You probably have a phone line you forgot about. It runs the fire alarm. Or the elevator. Or a fax machine nobody has touched since 2019. It is a POTS line, short for plain old telephone service, and it rides on copper.
That copper is going away. And the bill for what is left is going up.
What changed
For decades, the big phone companies had to keep copper lines working and keep the price in check. Then the FCC changed the rules.
On August 2, 2019, the FCC adopted Order 19-72 in WC Docket 18-141. It let the old phone companies drop most of their legacy copper obligations after a three year transition. That clock ran out on August 2, 2022.
Since then, AT&T, Verizon, and the other old phone companies have been free to do two things. Stop fixing copper. And charge what they want for it.
They are doing both.
Why your POTS bill jumped
A copper line used to be cheap. It was regulated. Now it is a product the carrier would rather you cancel. So they price it that way.
We see the same pattern on bill after bill. The line itself is a small number. Then the fees stack up. Access recovery charges. Federal subscriber line charges. A "maintenance" line that did not exist two years ago. The total is often several times what the same line cost before 2022.
Here is the part that stings. You are not paying for a phone. You are paying for a wire that carries a 30 second alarm test once a day.
The notice you may have missed
Carriers do have to say something before they pull the plug. The FCC copper retirement rules live at 47 CFR 51.332. They require notice to other carriers at least 90 days before the copper comes out.
But the rules for telling you, the retail customer, got thinner. The FCC trimmed those notice requirements in the 2017 Wireline Infrastructure Order under WC Docket 17-84. So the heads up often arrives as a line on page four of a bill. Or a letter addressed to whoever signed the account in 2011.
Check your bill for words like "grandfathered," "legacy," or "TDM." Those are the tells.
What actually needs a POTS line
Fewer things than you think. Walk the building and make a list. Most offices find three or four lines. Usually some mix of:
- Fire alarm panel
- Elevator phone
- Security alarm
- Fax
- A backup line for the credit card terminal
Now ask who still needs copper. The honest answer is almost nobody.
Fire alarm codes have caught up. NFPA 72 allows alarm panels to report over cellular and IP paths, not just copper. Elevator codes require two way voice from the car. They do not say it has to be a copper line. Your fire marshal and elevator inspector may have local rules on top of that. Ask them before you cut anything.
The cheaper ways to keep it working
You have three real options.
A cellular POTS replacement box. It plugs into the same jack the alarm panel uses today. The panel does not know the difference. It runs on a cellular signal and a battery backup. This is the most common fix we see.
Move the line to VoIP. Your phone system probably already runs over the internet. Some alarm panels and fax machines work fine on it. Some do not. Test before you switch. Alarm panels are picky about line voltage and timing.
Keep one copper line and kill the rest. If a local inspector insists on copper for one panel, fine. Pay for one. Not four.
Whichever you pick, do the math per line. The replacement box has a one time cost and a monthly fee. Put that next to what you pay the carrier now for the copper line, fees included. The box usually wins in under a year.
The order of operations
Do not cancel the copper first. That is how buildings end up with a dead fire alarm and a failed inspection.
Install the replacement. Test it with your alarm company. Get the inspector to sign off. Then cancel the copper. And get the cancellation in writing with a confirmation number. Carriers lose these requests.
One more thing. When you cancel, check the next two bills. The line should be gone. The fees tied to it should be gone too. About half the time, one of them is not.
Not sure what you are paying for? Upload your bill. We will show you every POTS line, every fee stacked on it, and what the replacement would cost. Takes about 60 seconds.
