POTS Replacement for Hospitals: What Healthcare Facilities Need to Know

Estimated reading time: 12 minutes

Hospitals and healthcare systems have more POTS lines than almost any other type of organization. Between fire alarm panels, nurse call systems, elevator phones, medical alert devices, and the communication infrastructure that runs across dozens or hundreds of facilities, a large hospital network can have thousands of active POTS lines spread across its portfolio.

That complexity makes POTS replacement in healthcare both more urgent and more consequential than in other industries. Carriers are retiring their copper networks on a timeline that does not account for the regulatory obligations healthcare facilities carry. A hospital that receives a disconnection notice for a fire alarm line cannot simply swap it out for a standard VoIP connection and move on. The compliance stakes, the patient safety implications, and the operational complexity all require a different level of planning.

This guide explains what healthcare facilities need to know about POTS replacement: which systems are at risk, which regulations govern them, and how to approach a transition that protects both compliance and continuity of care.

For most healthcare organizations, this conversation begins not as a strategic technology initiative but as a forced external event: a carrier retirement notice, a Joint Commission survey finding, a CMS inspection, or an insurance audit that surfaces a non-functional fire alarm communication path. The decision-makers are typically facilities directors, life safety officers, and compliance teams: people accountable for uptime and regulatory standing, not technology selection.

What Healthcare Facilities Use POTS Lines For

The assumption that POTS lines are only for telephone handsets is especially costly in healthcare, where analog lines quietly run a wide range of systems that most facilities teams have not fully inventoried.

• Fire alarm and suppression systems. Most fire alarm panels installed before 2015 use POTS lines as the primary communication path to monitoring centers and emergency services. NFPA 72, the national standard for fire alarm and signaling systems, mandates specific communication path requirements for alarm monitoring. A disconnected fire alarm line does not just create a compliance gap. It means a fire in the building may not trigger an emergency response.
• Elevator emergency phones. ASME A17.1, the Safety Code for Elevators and Escalators, requires a two-way means of communication in every elevator cab. In most hospital buildings, those elevator phones are wired to POTS lines. A hospital with multiple buildings and dozens of elevators can have a significant number of lines dedicated solely to elevator compliance.
• Nurse call systems. Many nurse call systems, particularly in older facilities, use analog telephone lines as part of their communication architecture. These are patient-facing life-safety systems, and interruption of service carries direct patient care implications.
• Medical alert and personal emergency response systems. Pendant-style emergency call devices and in-room patient call systems in long-term care, assisted living, and skilled nursing environments often use POTS lines as their communication backbone.
• Physician and staff paging systems. Legacy overhead paging infrastructure in hospital environments commonly routes through POTS-connected equipment.
• Fax machines and secure document transmission. Healthcare remains one of the highest-volume fax industries due to HIPAA requirements, referral workflows, and insurance claims processing. Many fax systems rely on dedicated POTS lines.
• Biomedical and diagnostic equipment. Certain imaging systems, infusion pumps, and remote monitoring devices with built-in dial-up communication capabilities use POTS lines for remote diagnostics, software updates, or data transmission.
• Security and access control. Gate dialers, door intercoms, and security alarm panels across hospital campuses and parking structures are frequently wired to POTS lines.

In a healthcare system with multiple hospitals, clinics, medical office buildings, and affiliated care facilities, the total POTS line count can easily exceed several thousand lines. Many of these are in locations and on systems that have not been actively reviewed since installation.

The Regulatory Environment for Healthcare POTS Lines

Healthcare facilities operate under a more complex and demanding regulatory environment than most other industries. POTS line replacement decisions cannot be made on cost or convenience alone. Each system type carries its own compliance framework.

NFPA 72: Fire Alarm Communication

The NFPA 72 National Fire Alarm and Signaling Code governs how fire alarm systems communicate with monitoring centers and emergency services. Under NFPA 72, alarm systems are required to have compliant communication paths, and the specific requirements vary depending on the edition of the code adopted by the local authority having jurisdiction (AHJ).

A key consideration for healthcare facilities is that fire alarm panels certified under older NFPA editions were designed and tested around analog POTS signaling. Replacing the communication path requires a solution that maintains the same signaling characteristics, not just equivalent voice-grade connectivity. A purpose-built managed POTS replacement solution that provides a true analog interface is the appropriate path, not standard VoIP.

See our detailed breakdown of NFPA 72 2025 requirements for current standards and what they mean for healthcare facilities.

ASME A17.1: Elevator Emergency Communication

ASME A17.1 requires a two-way means of communication that connects elevator passengers to building staff or emergency services. The code requires that the communication system be capable of operating for at least one hour on battery backup if normal building power is lost, mirroring the loop power characteristic of traditional POTS lines.

Any replacement for elevator POTS lines must satisfy this requirement. A managed POTS replacement solution with battery backup, or a purpose-built cellular elevator communication unit, meets the standard. Standard VoIP does not.

The Joint Commission and CMS Conditions of Participation

Hospitals accredited by The Joint Commission and those participating in Medicare and Medicaid are subject to Environment of Care (EC) and Life Safety (LS) standards that govern fire alarm systems, emergency communication, and overall facility safety infrastructure.

A fire alarm system that cannot communicate with a monitoring center due to a disconnected POTS line is a direct Life Safety deficiency. Findings of this type during a Joint Commission survey or a CMS inspection can result in immediate jeopardy determinations, which carry significant consequences including accreditation risk and potential loss of Medicare and Medicaid reimbursement.

State Health Department Licensing

State health departments conduct their own licensing surveys of hospitals, nursing homes, and licensed healthcare facilities. Many states adopt NFPA 72 by reference in their licensing regulations, making a non-functional fire alarm communication path a licensing violation as well as a code violation.

The Specific Risks of Inaction in Healthcare

The consequences of a missed or delayed POTS transition are more severe in healthcare than in almost any other setting.

• Patient safety. Fire alarm systems and emergency communication devices are patient safety infrastructure. A fire in a hospital wing with a non-functional alarm communication path puts patients, visitors, and staff at risk. The obligation here extends beyond regulatory compliance.
• Joint Commission immediate jeopardy. An immediate jeopardy finding during a survey is the most serious determination a hospital can receive. It indicates that a deficiency has placed patients in immediate danger. Facilities that receive IJ findings must correct the condition immediately or face suspension of accreditation. POTS line disconnection affecting fire alarm communication can constitute grounds for an IJ finding.
• CMS reimbursement risk. Hospitals that lose Medicare and Medicaid certification due to life safety deficiencies face immediate and severe financial consequences. For most hospitals, Medicare and Medicaid reimbursement represents the majority of revenue.
• Liability exposure. A patient, visitor, or staff member injured in an incident that could have been prevented by a functioning emergency communication system creates significant liability. The fact that a facility received a disconnection notice and did not act on it is a serious aggravating factor.
• Operational disruption. Nurse call outages, paging system failures, and diagnostic equipment communication losses create immediate operational problems that divert staff time, disrupt care workflows, and generate incident reports.

Why Healthcare POTS Replacement Requires a Different Approach

The line-by-line replacement approach that many organizations default to is particularly inadequate in healthcare for several reasons.

• Scale. A large hospital system may have hundreds of locations and thousands of lines. Managing each line individually, coordinating with the existing alarm vendor for each panel, scheduling installation around patient care activities, and verifying compliance at each site requires a program management capability that most internal facilities, operations, and compliance teams do not have the bandwidth to sustain alongside normal operations.
• Device complexity. Healthcare POTS lines serve a wider range of device types than most industries, including devices governed by biomedical and clinical engineering standards. The replacement decision for a fax machine is straightforward. The replacement decision for a fire alarm panel in a hospital that was last certified under NFPA 72 2010 requires consultation with the AHJ, the alarm vendor, and the facility’s life safety officer.
• Care environment constraints. Installation work in patient care areas requires coordination with nursing and clinical staff, must occur without disrupting monitoring equipment, and in some settings requires infection control protocols. This is a meaningfully different operational environment than a commercial office building.
• 24/7 operations. Hospitals do not close. Installation windows must be carefully planned, and any transition that interrupts communication systems must be executed with zero tolerance for extended outages.

MarketSpark’s hospital case study demonstrates what a well-executed transition looks like at scale: a leading hospital system successfully completed POTS replacement across more than 490 locations, achieving full digital transformation of life-safety connectivity and voice infrastructure, with 24/7/365 support and predictable flat-rate billing going forward.

What to Look for in a Healthcare POTS Replacement Partner

Not all POTS replacement providers are equipped to handle the specific demands of healthcare environments. The key criteria to evaluate:

• Life-safety compliance. The provider must understand NFPA 72, ASME A17.1, and Joint Commission and CMS standards as they apply to communication paths. A solution that passes a commercial office inspection may not satisfy the requirements for a hospital fire alarm system. Ask specifically about compliance with the AHJ requirements in each jurisdiction where your facilities are located.
• Analog interface fidelity. Fire alarm panels and other life-safety devices require a true analog interface with the correct signaling characteristics. Confirm that the replacement solution provides this, not a VoIP line with an adapter that approximates analog behavior.
• Battery backup. Replacement solutions for elevator phones and fire alarm communication paths must maintain operation during a building power outage. Confirm the battery backup duration and whether it meets ASME A17.1 and NFPA 72 requirements.
• Nationwide installation capability. Healthcare systems have locations in multiple states. A provider that can handle nationwide installation with consistent standards and credentialed technicians eliminates the complexity of managing multiple regional vendors.
• Centralized monitoring and visibility. The ability to see the status of every line across every location in real time is critical for healthcare compliance management. MarketSpark’s Command Center Platform provides exactly this, with real-time status visibility, device online notifications, and detailed reporting across all locations and lines.
• Program management capability. Healthcare POTS replacement is a multi-year, multi-site program, not a one-time project. The provider should offer structured program management, including the initial line audit, site-by-site project planning, coordination with clinical and facilities teams, and ongoing support.

Getting Started: The Healthcare POTS Replacement Roadmap

The right starting point for any healthcare system is a comprehensive audit of every POTS line across every facility. This means:

1. Identifying every active POTS line across hospitals, medical office buildings, clinics, long-term care facilities, and affiliated sites
2. Documenting what each line is connected to and which compliance framework governs it
3. Categorizing lines by risk level, with life-safety systems (fire alarms, elevator phones, nurse call) as the highest priority
4. Mapping the appropriate replacement for each device type, accounting for device-specific compliance requirements
5. Developing a phased transition plan that prioritizes high-risk lines and accommodates care environment installation constraints
6. Establishing monitoring and reporting to maintain compliance visibility throughout the transition and beyond

Starting this process before a carrier retirement notice, a survey finding, or an insurance audit forces the issue gives your organization control over the timeline and ensures that life-safety systems are never at risk of unplanned disruption.

If your healthcare system has received a carrier notice, is preparing for a Joint Commission survey, or has an upcoming CMS inspection, contact MarketSpark to discuss a managed POTS replacement program.
