Know Your POTS Phone Line Replacement Options: VoIP, Cellular 5G/LTE, or Cloud-Based Solutions

Your building may already be noncompliant, and you might not even know it.

As telcos quietly phase out copper infrastructure, thousands of businesses are left relying on analog phone lines that are no longer supported. 

Fire alarms, elevator phones, security systems; they’re all at risk of silent failure. In fact, building inspectors and fire marshals are already flagging properties with aging POTS lines as out of code in many jurisdictions.

But here’s the catch: the FCC didn’t mandate a centralized shutdown date. So every provider is retiring lines on their own schedule, leaving businesses to figure it out in real-time.

This blog post will walk you through your replacement options, from VoIP to 5G/LTE to cloud-based POTS alternatives, so you can stay compliant, protect building occupants, and avoid unnecessary risk. 

You’ll also see why Atlantech|POTS offers the most complete solution for businesses that rely on life-safety systems and critical infrastructure.

Why You Need to Replace POTS Lines in 2025

In 2019, the FCC gave telecom providers the go-ahead to stop maintaining their copper networks. Since then, service reliability has dropped sharply, and monthly line costs have exploded; in some regions, surcharges exceed $200 per line.

That’s not just frustrating. It’s dangerous.

Failing copper infrastructure puts your fire alarms, elevators, and emergency lines at risk. With no federal mandate for centralized shutoffs, many businesses won’t find out until they’re already down.

If a line fails today, there’s no repair guarantee. The time to act is now.

“A lot of property managers still assume the copper line will be repaired if it goes down, but that’s no longer guaranteed. Carriers are under no obligation to fix it, and in many cases, there’s no technician left to call.” — Ed Fineran, President, Atlantech Online

What Makes a Good POTS Replacement?

Most businesses don’t just need dial tone. They need:

• Compatibility with analog hardware (e.g., elevator phones, fire alarms)
• 24/7 uptime, even during internet or power outages
• Compliance with NFPA 72, ADA, and local inspection codes
• Remote monitoring, alerts, and battery backup
• One point of contact, not a patchwork of vendors

Choosing the wrong option can result in inspection failures, liability exposure, or hours of downtime you can’t afford.

POTS Phone Line Replacement Options

Option 1 – VoIP (Voice over IP)

Pros:

• Affordable and easy to deploy
• Leverages your existing internet connection
• Ideal for desk phone and standard voice use

Cons:

• Not compliant for life safety systems like fire alarms or elevators
• Relies entirely on internet uptime
• Often incompatible with legacy analog hardware

Best For:

• Low-priority lines like internal office phones or low-risk fax lines.
  
  

Option 2 – Cellular 5G/LTE-Based POTS Replacement

Pros:

• Doesn’t rely on internet connection — uses LTE for connectivity
• Compliant with NFPA 72 as a Managed Facilities Voice Network (MFVN)
• Ideal for legacy systems like elevator phones and alarm panels
• Offers backup power, failover, and remote monitoring

Cons:

• Requires on-site hardware
• Slightly higher upfront cost

Best For:

• Fire alarms, security systems, elevator phones, and buildings with aging analog infrastructure.
  
  

Option 3 – Cloud-Based POTS Replacement

Pros:

• Scalable and centrally managed
• No on-site hardware for voice-only systems
• Great fit for digital-first businesses

Cons:

• Often depends on a reliable internet connection
• May not support analog-based life safety systems
• Usually requires system upgrades or rewiring

Best For:

• Cloud-native environments without life safety compliance needs.
  
  

How to Choose the Right POTS Replacement for Your Property

The right solution depends on what systems you're supporting, your compliance requirements, and the level of risk you can tolerate.

Ask yourself:

• What’s running on these lines (fire, elevator, fax, security)?
• What codes do I need to comply with (NFPA, ADA, etc.)?
• Can I afford downtime during an outage?
• Who will monitor and maintain this system, me or a vendor?
  
  

Quick POTS Replacement Vendor Selection Tips

Quick questions to ask potential vendors:

• How do you support systems like elevators, fire panels, and emergency call boxes?
• What’s your average installation timeline from contract to activation?
• Do you offer managed services or ongoing monitoring?
• How do you handle outages or failover protection?
• Can you support multi-property or campus-wide deployments?

Red flags to watch for:

1. Vague or generic answers about life-safety or compliance systems
2. No mention of backup power, failover, or battery support
3. Pricing that sounds too good to be true or excludes install costs
4. Lack of familiarity with local fire code, elevator code, or AHJ requirements
5. No case studies or customer examples in similar environments

Reference checking guidelines:

• Ask for references from building owners, property managers, or facility directors
• Prioritize customers with similar system types (e.g. elevators, fire panels, entry gates)
• Request recent installs (within the last 6–12 months) for current feedback
• Ask references about communication, post-install support, and billing accuracy

Contract considerations:

• Look for service level agreements (SLAs) related to uptime, response time, and support
• Understand all fees: install, equipment, monthly service, and any cancellation terms
• Ensure the vendor takes responsibility for compliance with AHJ or inspection standards
• Request written confirmation of what systems they support and how
