For decades, Plain Old Telephone Service (POTS) lines have been the backbone of business communication. From fax machines and fire alarms to elevators and emergency call boxes, POTS lines have reliably delivered analog voice services over copper wires. But in today’s digital-first world, the days of relying on POTS are numbered.

Major carriers are actively phasing out copper infrastructure, increasing prices, and reducing support. If your business is still using POTS, it’s not a matter of if you should replace them—it’s when. And the answer is: now.

As an independent technology advisor, I work closely with businesses of all sizes to modernize their communications infrastructure. In this post, I’ll explain why replacing POTS lines is not just a smart move—it’s a strategic one. I’ll also outline the best alternatives available today and the potential ROI you can expect from making the switch.

The Problem with POTS

POTS lines may still work for now, but there are growing risks and costs associated with sticking to outdated technology:

• Rising Costs: Carriers have increased prices significantly on POTS lines, sometimes charging $100 or more per line, per month.
• Decreasing Support: Telecom providers are no longer maintaining copper lines with the same urgency. Some providers are even refusing new service requests altogether.
• Regulatory Changes: In 2019, the FCC issued an order (FCC 19-72A1) that allows carriers to discontinue POTS services without replacing them.
• Limited Functionality: POTS lines don’t support modern communication needs, such as remote work, integration with CRMs, or unified communications.

Holding onto legacy systems may seem safe, but it’s becoming increasingly risky and expensive.

Modern Alternatives to POTS

Fortunately, there are powerful, cost-effective alternatives that can replace POTS lines without sacrificing reliability. Here are some of the most common options:

1. VoIP (Voice over Internet Protocol): VoIP uses your internet connection to deliver voice services. It’s flexible, scalable, and far more cost-effective than traditional lines.
2. Cellular POTS Replacement Devices: These devices use 4G LTE or 5G cellular networks to emulate analog line functionality. Perfect for use cases like alarm systems, elevators, and emergency phones.
3. SIP Trunks: SIP (Session Initiation Protocol) trunking connects your on-premises PBX to the internet, providing high-quality voice services without relying on copper lines.
4. Cloud-Based Phone Systems: Hosted VoIP or UCaaS (Unified Communications as a Service) platforms provide voice, video, messaging, and mobility in one integrated solution.

Each of these solutions can be tailored to your business needs, ensuring both functionality and compliance with safety or regulatory requirements.

How to Evaluate the Right Replacement for Your Business

Not all POTS replacements are created equal. 

A good solution should be:

• Reliable: Especially for life-safety systems and compliance requirements.
• Cost-Efficient: Delivers measurable savings over legacy systems.
• Scalable: Can grow with your business.
• Flexible: Supports hybrid work, mobile employees, and cloud integration.

Working with an independent advisor ensures you’re not locked into one vendor. I help businesses perform a full audit of current POTS usage and match them with the most effective, future-ready solution.

The ROI of Replacing POTS

Replacing legacy phone lines may seem like a capital expense, but the return on investment is clear and compelling:

• Cost Savings: Businesses often reduce line costs by 40-60%.
• Operational Efficiency: Simplified management, less downtime, and better functionality.
• Productivity Gains: Employees gain access to modern features like voicemail-to-email, mobile apps, and call analytics.
• Reduced Risk: Avoid outages or compliance failures from unsupported POTS infrastructure.

Consider this: A company with 20 POTS lines paying $100/month per line is spending $24,000 annually. A modern solution could reduce this to $10,000 or less, with added features and reliability.

Making the Transition

Here’s what the process typically looks like when working with an advisor:

1. Assessment: We review every line to determine its use case and criticality.
2. Solution Design: Match each use case (e.g., fire panel, elevator, fax) to the right modern alternative.
3. Vendor Selection: Evaluate providers based on cost, reliability, and support.
4. Implementation: Ensure seamless migration with minimal disruption.
5. Ongoing Support: Monitor, manage, and optimize over time.

Because we’re vendor-neutral, we focus solely on what’s best for your business.

Don’t Wait Until It Breaks

Many businesses hold off replacing their POTS lines until something goes wrong—an outage, a price hike, or a system failure. But by then, it’s often more expensive and disruptive to fix.

Instead, take control of the transition. You’ll not only save money but also future-proof your infrastructure for whatever comes next.
