The Texas POTS Sunset Is Here: Replace Copper Lines Now

The short version: maintaining the old copper network is expensive, the people who know how to fix it are retiring, and the FCC has cleared a path for carriers to retire it. AT&T has been signaling this for years — we wrote about AT&T decommissioning copper lines by 50% well before this became urgent. Now it is here.

Two things have already happened that should get your attention. First, an October 2025 grandfathering notice froze all new POTS and specialty-line orders across much of AT&T's footprint, and Texas is among the hardest-hit states. That means you can no longer add a copper line — if you open a new office, a new suite, or need another analog circuit for a fire panel, that option is simply gone.

Second, the physical shutdown across roughly 500 wire centers begins this month. A wire center is the local facility that serves your specific address. When yours is scheduled for retirement, every copper line riding it is on a countdown. The painful part for most Texas business owners is that the lines being shut off are rarely the ones you think about. Nobody forgets their main office phone. Everybody forgets the analog line buried in the elevator shaft.

Here is the mechanism that turns this from "a thing to handle eventually" into a hard operational deadline. When AT&T issues a formal discontinuance notice for your wire center, you can have as little as 180 days to migrate before that line goes dead. (That 180-day window is the business / non-residential figure; residential lines get only 90.) Six months sounds like a lot until you realize what is involved: inventorying lines nobody documented, scheduling an elevator inspection, coordinating with your fire alarm company, and getting an authority having jurisdiction (AHJ) sign-off. That timeline disappears fast.

And waiting is not free. Carriers are already raising copper-line rates 200 to 400 percent, with some legacy lines now exceeding $2,700 per month. Read that again — a single analog line you forgot you were paying for can now cost more than a small employee's monthly salary. Carriers are using price to push you off copper before they have to physically retire it. Every month you delay is a month you may be overpaying enormously.

The takeaway is simple: do not wait for the discontinuance notice to start working the problem. By the time that letter arrives, your most complicated migration — the life-safety lines — is already on a 180-day fuse. Start the inventory now, while you still have room to plan instead of scramble.

You cannot migrate what you cannot see. The first and most important step is a complete inventory of every analog line in your building. This is harder than it sounds, because POTS lines have a habit of hiding in plain sight. Pull your carrier bills and account every billed line back to a physical device. The usual suspects:

• Elevator emergency phones. Code requires a working two-way phone in every elevator cab. It is almost always an analog POTS line, and almost nobody in IT knows it exists.
• Fire alarm panel dialers. Many older fire panels report to the monitoring center over a pair of copper lines. If those go dead, your monitoring goes dark.
• Burglar and intrusion alarm dialers. Same story as the fire panel — the alarm may "phone home" over copper.
• Fax lines. Still common in medical, legal, and title offices across Texas.
• POS and credit card terminal backup lines. Older terminals dial out over analog when the network is down.
• Gate and entry intercoms, modems for utility metering, and overhead paging. The forgotten corners.

Walk the building. Match every line on the bill to a device, and flag the ones nobody can identify — those are exactly the ones that will bite you. This inventory is the foundation of everything that follows, and it is the part a partner with managed IT services in Texas can take off your plate quickly because we do this kind of discovery for a living.

This is where businesses get burned, so slow down here. The instinct is to move everything to VoIP because it is cheaper. For your office phones, great — do it. For your elevator phone and fire alarm dialer, that instinct can put you out of code compliance and, worse, leave people unable to call for help.

Standard VoIP has two problems for life-safety endpoints. First, it loses dial tone in a power outage — exactly when someone is most likely trapped in an elevator or when a fire knocks out power. Second, it may not meet the line-supervision and reliability requirements that elevator and fire-alarm code expect from a real analog line. A fire panel is built to detect when its line is cut and raise a trouble signal; consumer-grade VoIP does not behave the way the panel expects.

For these endpoints, the safer path is a POTS-in-a-Box or cellular failover device that presents a genuine analog dial tone, backed by battery and a monitored cellular connection. The device sits where the copper line used to terminate, the elevator phone or fire panel sees a normal dial tone, and the connection rides cellular instead of dead copper. Critically — and this is non-negotiable — confirm the specific solution against your AHJ and your elevator and fire-panel manufacturer's requirements before you cut over. Code compliance lives with the inspector, not the salesperson.

There is no single right answer. The right plan usually mixes all three, matched to what each line actually does.

VoIP (Voice over IP). Best for standard business voice — desk phones, conference rooms, main lines, fax over fax-grade VoIP where appropriate. It typically lowers your ongoing bill and adds features. The catch: it depends on your internet and power, so it needs a solid network and battery backup behind it. This is the right move for the bulk of your conversational lines.

POTS-in-a-Box / cellular failover. Best for life-safety and machine-to-machine lines — elevators, fire and burglar alarms, gate phones, and any device that must keep working when the building loses power or internet. The device delivers real analog dial tone over a cellular link with battery backup, and good ones are monitored 24/7 with automated alerts so a failed connection is caught before you need it. (To be clear: that 24/7 monitoring is automated device health-checking, not a promise that a human answers at 3 a.m.)

Full fiber / managed network. The long-term foundation. If you are touching the building's connectivity anyway, this is the moment to evaluate whether your network can carry voice, life-safety failover, and data reliably. A modern Network as a Service (NaaS) model or a properly designed managed network removes the guesswork and gives you a single, supported platform instead of a patchwork of dying copper.

Decide line by line. A fax does not need what an elevator needs, and your front-desk phone does not need what a fire panel needs.

Once you have your inventory, sequence the work by risk, not by convenience. The order that keeps you safe and compliant:

• Life-safety first. Elevators and fire alarm lines go to the front of the queue. They have the longest lead time because of AHJ and manufacturer coordination, and they carry the most risk if they fail. Start these the day you finish the inventory.
• Deadline-critical second. Any line on a wire center that has already received a discontinuance notice. The 180-day clock dictates the schedule, not your preference.
• Cost-bleed third. The lines getting hit with 200 to 400 percent rate hikes. Migrating these stops the financial bleeding fast.
• Convenience lines last. Fax, paging, and similar lines you can move on a normal schedule once the urgent work is done.

The trap to avoid is a compliance gap — a window where the old line is dead but the new solution is not yet tested and signed off. Never let copper get cut before the replacement is installed, verified, and accepted by the inspector. Build overlap into the schedule on purpose. For complex sites, this often pairs naturally with broader managed network and structured cabling services so the cabling, the failover devices, and the network all come from one accountable plan instead of three vendors pointing at each other.

The honest answer on cost is that it depends — on how many lines you have and what they connect to — so it is a per-project decision, not a flat monthly figure. But the financial story most owners miss is the cost of doing nothing. With legacy lines exceeding $2,700 per month and rate hikes of 200 to 400 percent already landing, inaction is frequently the most expensive option on the table.

Here is where the money actually moves. Migrating standard voice to VoIP usually lowers your ongoing bill, sometimes substantially. Life-safety lines move to a fixed, predictable cost on a cellular failover device — you trade an unpredictable, climbing copper bill for a known monthly number. The real risk is not the migration spend; it is getting caught on the wrong side of a discontinuance date with a dead elevator phone and an inspector at the door.

Treat this like the operational deadline it is. Inventory every line, map each to the right replacement, sequence by risk, and leave overlap so nothing goes dark mid-cutover. Do that, and the copper sunset becomes a one-time project that ends with a cheaper, more reliable phone and network setup. Ignore it, and it becomes an emergency on someone else's timeline.

When does AT&T actually shut off copper POTS lines in Texas?

The physical copper shutdown begins in June 2026 across roughly 500 wire centers nationwide, and Texas is heavily affected. An October 2025 grandfathering notice already froze all new POTS and specialty-line orders across much of AT&T's footprint — with Texas among the hardest-hit states — so you can no longer add lines. The hard part is the discontinuance clock: once AT&T issues a discontinuance notice for your wire center, you can have as little as 180 days to migrate before the line goes dead. Don't wait for the notice — inventory your lines now.

Can I just move my elevator and fire alarm phone lines to VoIP?

Usually not directly, and this is where businesses get burned. Standard VoIP loses dial tone in a power outage and may not meet the line-supervision and reliability requirements that elevator and fire-alarm code expect from an analog line. For these life-safety endpoints the safer path is a POTS-in-a-Box or cellular failover device that presents a real analog dial tone with battery backup and a monitored cellular connection. Always confirm the specific solution against your AHJ (authority having jurisdiction) and elevator/fire-panel manufacturer requirements before you cut over.

What does it cost a Texas SMB to replace POTS lines?

It varies by how many lines you have and what they connect to, so it's a per-project decision rather than a flat monthly number. The bigger financial story is the cost of doing nothing: carriers are already raising copper-line rates 200 to 400 percent, with some legacy lines now exceeding $2,700 per month. Migrating standard voice to VoIP often lowers your ongoing bill, while life-safety lines move to a fixed-cost cellular failover device.
