It always starts the same way. A call box goes silent in the parking garage. An elevator emergency line fails its monthly test. Maybe it’s even something less dramatic.
A weird buzz on the fax line, dropped phone calls to the fire alarm panel, a maintenance ticket that turns into a multi-day standoff with your local telecom provider.
Whatever the failure, one thing becomes clear fast: you’re overdue for a POTS replacement.
If that sounds a little intimidating, fair enough. Between the acronyms, compliance concerns, and “wait, we still have fax machines?” moments, it’s hard to know where to even begin.
That’s why we wrote this guide.
Below, we’ll break down why the clock has officially run out on analog POTS lines, what to do about it, and how to modernize without blowing up your operations.
What Exactly Are POTS Lines, and Why Are They Still Hanging Around?
“POTS” stands for “public switched telephone network” or “plain old telephone service,” and that’s exactly what it is: analog copper lines that have been around since the Bell System era.
Long before Wi-Fi and fiber, these analog phone lines were the gold standard for reliability. They were the go-to for systems that needed a guaranteed dial tone. That’s why you’ll still find them:
- Running the elevator phones in office towers.
- Connecting fire alarms and safety systems to monitoring centers.
- Powering fax machines in hospitals, banks, and government offices.
- Serving as backup lines for modems and legacy connectivity.
Many businesses are hesitant to replace the “old reliable” telephone service line. Not just because it’s a hassle to rip and replace infrastructure, but also because if it isn’t broken. . .why fix it?
The trouble is, legacy POTS lines are broken, just not in a way that’s always obvious.
Don’t worry, we’ll explain.
Why POTS Line Replacement Can’t Wait Anymore
In 2019, the FCC gave carriers the green light to retire copper networks and stop supporting traditional POTS. Translation: phone companies no longer have to maintain the existing POTS lines that keep your alarms, elevators, and fax machines alive.
The fallout has been slow, but painful:
- Costs are spiking: It’s not unusual to see a single POTS line billed at $80–$150 per month. Multiply that by dozens or hundreds of lines, and you’re pouring money into something your carrier doesn’t even want to maintain anymore.
- Reliability is fading: Copper lines are aging, techs who service them are retiring, and outage repair times keep creeping up. When alarms or elevators depend on those lines, that’s not just annoying, it’s dangerous.
- Compliance risk is real: Building codes and safety standards require functioning lines for fire, security, and elevators. If POTS fails and you’re not prepared, liability comes knocking.
- Technology has outpaced it: Cloud and IP-based solutions offer monitoring, redundancy, and flexibility that POTS will never match.
The good news? The fabled “copper sunset” has an upside (and a pretty big one at that). So, if you’ve been tolerating POTS lines because “they still work most of the time,” this next section’s all yours.
The Benefits of Moving Beyond POTS Phone Lines
Moving tomodern POTS replacement solutions not only helps you get ahead of the shutdown. It also benefits your balance sheet and your day-to-day operations.
Counting the Dollars: Why POTS Replacement Pays Off Fast
Right now, POTS lines are money pits. They cost more to maintain, more to repair, and more to operate than digital alternatives.
Say you’ve got 100 POTS lines across your enterprise at an average of $100 per line, per month. That’s $10,000 every month, or $120,000 a year, just to keep old copper on life support.
With digital alternatives, you’re looking at anywhere from $30–$50 per line, plus the benefit of consolidation. That same 100-line footprint could drop to $3,500–$5,000 a month. Over a year, that’s $60,000–$80,000 back in your budget.
Those cost savings add up to:
- No more surprise repair costs. Copper lines are notorious for sudden breakdowns and pricey fixes. With virtual POTS line replacement options, you’re dealing with modern infrastructure that’s easier (and cheaper) to maintain.
- Fewer headaches during inspections. When your elevator phone works every time and your alarm lines stay connected, you pass inspections without drama. No fines, no delays, no angry building managers.
- Your team gets their time back. Instead of chasing down copper issues, they can focus on enterprise telecom upgrades and the projects that actually move your business forward.
Bottom line: every month you put off a phone line replacement solution is another massive copper surcharge you didn’t need to pay. POTS replacement isn’t just cheaper, it’ll help you put an end to that slow budget leak.
POTS Replacement Wins: Stories That Show It Works
Still skeptical? Here’s what POTS replacement can look like when it’s done right:
- A national retail chain might cut over 600 POTS lines tied to alarms and faxes across 200 locations. That kind of move can shrink a bloated telecom bill by six figures and centralize everything into one clean monitoring dashboard.
- A hospital system could migrate critical alarm and elevator lines without downtime, using LTE failover to keep essential systems online no matter what the weather’s doing.
- A high-rise office tower might move all of its elevator emergency phones to digital. Not only would they pass inspection with zero drama, they’d gain monitoring tools that flag issues before inspectors ever show up.
The proof is in the outcome. Enterprises making the switch aren’t just avoiding disaster; they’re improving reliability and cutting costs while they’re at it.
The Enterprise POTS Replacement Roadmap (Step-by-Step)
Knowing you need to replace traditional landline phone systems is one thing. Doing it without disrupting essential services? That’s another beast entirely. Here’s a quick playbook on how to tackle your POTS service upgrade:
Step 1: Assess
Inventory every POTS line. That includes the “forgotten” ones tucked into basements and mechanical rooms. You can’t replace what you don’t know exists.
Step 2: Plan
Map each line to its use case. Security and fire alarm systems? Elevator phones? Fax? Each has a best-fit replacement, whether it’s a VoIP adapter, a wireless gateway, or a SIP trunk.
Step 3: Test
Pilot the most critical systems before a full rollout. If your fire alarms don’t report during a test, you need to know before you rip out the old line.
Step 4: Deploy
Roll out in phases, site by site. Keep redundancy in place until you’re confident the new solution works. No one wants to explain to the COO why an elevator call didn’t go through during “migration week.”
Step 5: Support
Replacement isn’t a one-and-done. Ongoing monitoring, software updates, and vendor support ensure your new system stays reliable for the long haul.
Take it step by step, and POTS replacement stops looking like a risky overhaul and starts looking like the smart upgrade it really is.
Frequently Asked Questions About POTS Replacement
Even with the roadmap laid out, a project this big comes with plenty of “yeah, but what about…” questions. That’s normal. Enterprises that are tackling POTS replacement ask the same handful of things every time, so let’s clear them up right here.
Q: Isn’t Voice over Internet Protocol (VoIP) unreliable if the internet goes down?
A: Not with the right setup! Enterprise-grade POTS replacement includes LTE backup or dual connectivity. If one fails, traffic routes automatically.
Q: What happens to fax machines?
A: Fax over IP has been a challenge in the past, but with the right analog terminal adapters (ATAs) and error-correction protocols, it can work reliably.
Q: How do elevators and fire alarms stay compliant?
A: Modern POTS replacement solutions are tested against fire codes, elevator codes, and UL standards. The right provider ensures security system compliance before rollout.
Q: How long does an enterprise rollout usually take?
A: Depends on scale. A single site can be done in a day. A nationwide rollout might take weeks, but with a standardized playbook, disruption is minimal.
Q: What should enterprises look for in a POTS replacement solutions provider?
A: You want more than a box. Look for:
- Nationwide coverage so that every site, from headquarters to the smallest branch, gets the same reliable rollout.
- Experience integrating legacy systems because alarms, elevators, and faxes don’t magically modernize themselves.
- Compliance expertise so that inspectors sign off without hesitation, and you stay out of regulatory hot water.
- Enterprise-grade monitoring and support because problems don’t keep office hours, and downtime is never optional.

Q: Do we need new hardware everywhere?
A: Usually not. The replacement device uses your existing analog devices, and your existing alarms, faxes, and elevators keep working as-is. It’s a behind-the-scenes swap, not a full rip-and-replace.
Q: Can’t we just keep a few POTS lines for critical systems and move the rest?
A: You could, but it’s like paying premium prices for cable just to watch one channel. Carriers are phasing out copper, so you’ll still face rising costs and long repair times. Better to move everything now than play catch-up later.
