Why POTS Replacement Solutions Need SD-WAN and Cybersecurity

Millions of Legacy Lines Still Need Replacing

🚨 Alarms | 🛗 Elevators | ☎️ Phones | 📟 Sensors | 📠 Fax | 💳 PoS

Even in 2025, there are still tens of millions of analog lines in use for mission-critical systems such as fire and intrusion alarms, HIPAA-compliant fax lines, elevator phones, security systems, and emergency call boxes 🚨.

Estimates show there are up to 30 million legacy POTS lines still active across North America. Many are found in healthcare, education, and commercial buildings where legacy equipment cannot easily be replaced. These lines remain essential for safety, compliance, and emergency access.

At the same time, the major telecom providers are phasing out copper infrastructure. For example, AT&T has announced its plan to retire its copper network by 2029, ending sales of traditional POTS and DSL services in many areas. In 2025 alone, AT&T filed with regulators to retire copper in about 1,300 of its 4,600 wire centers.

Other carriers are following suit, stopping new installations or moves, adds, and changes to POTS lines. Maintaining copper has become expensive, energy-inefficient, and unreliable as the network ages and repairs take longer. The direction is clear: copper is going away.

For VoIP, UCaaS, and MSP providers, this shift creates both a challenge and an opportunity. The challenge is how to migrate these analog systems securely and reliably. The opportunity is to provide customers with a modern, managed solution that adds value and peace of mind.

Many “basic” POTS replacement devices on the market focus only on getting dial tone working again. Unfortunately, most of them fail to protect or ensure uptime.

Common weaknesses include:

❌ No firewall or cybersecurity protection, leaving your networks and supply chains open to attack

❌ Single Internet connection, which goes down when broadband fails

❌ Missing 24 HRS worth of Backup Power

❌ No proactive monitoring or alerting

❌ Limited or no visibility for MSPs or UCaaS providers

These gaps create risk, especially for safety and compliance systems that must stay online at all times.

RabbitRun’s POTS Replacement Kit goes beyond dial tone and delivers a fully managed solution designed for uptime, visibility, and protection.

It includes:

✅ SD-WAN router with multi-carrier cellular failover for guaranteed connectivity

✅ Dual redundant power supplies for dependable performance

✅ Enterprise-grade firewall and built-in cybersecurity

✅ Rugged IP67-rated enclosure for harsh environments

✅ Fully managed and monitored service for partners and customers

This gives VoIP and UCaaS providers a complete, ready-to-deploy solution that ensures both reliability and security.

RabbitRun’s system includes advanced monitoring and alerting tools that help providers stay ahead of issues before they impact customers.

☁️📞 SIPWatch Alerts – Monitor the registration status of SIP accounts linked to critical endpoints such as alarm panels, elevators, or safety phones. When a device deregisters or re-registers, RabbitRun automatically sends an alert so the provider can take action immediately.

⚡🔋 PowerWatch Alerts – Detect when building power goes out or comes back online and send instant email notifications. MSPs can respond proactively and inform customers before they even call in.

☁️🌐 Broadband Failover Alerts – Know the moment a broadband connection goes down or comes back up. RabbitRun automatically switches to cellular and sends an alert to your team so you can confirm service continuity and troubleshoot remotely.

These intelligent alerts provide real-time insight and visibility, allowing MSPs and UCaaS partners to deliver a more proactive and dependable service experience.

Reliable connectivity, intelligent failover, and built-in protection work best when they operate together. Combined, they keep life-safety systems, alarms, and voice services Always-On and secure.

Many POTS replacement devices depend on a single broadband connection, creating a single point of failure.
When an Internet outage or cyberattack occurs, voice, alarm, and safety systems can go offline instantly.

RabbitRun’s SD-WAN architecture removes that risk by uniting connectivity, security, and intelligent routing in one managed solution.

It delivers:

🔀 Automatic switching between broadband and multi-carrier LTE failover

🛡️ Built-in Cyber Threat Protection to block malicious traffic

📶 Traffic shaping and prioritization for clear, stable voice calls

Together, these create true network resilience, keeping critical communications online, secure, and Always-On.

POTS lines are disappearing quickly as carriers retire the aging copper network.

Yet millions of businesses still depend on these lines for alarms 🚨, elevators 🛗, and fax systems 📠, and the clock is ticking ⏳.

When life-safety and compliance systems rely on your solution, reliability and security are non-negotiable.

You need a strategy that ensures uptime, protection, and proactive visibility at all times.
