South Florida POTS Line Costs Are Exploding — Your Exit Options Explained

What's Happening to POTS Lines in South Florida

The FCC's 2022 ruling allowing telecommunications carriers to retire legacy copper telephone infrastructure — Plain Old Telephone Service (POTS) lines — has triggered a wave of rate increases that South Florida commercial and multi-family property owners are only beginning to feel. AT&T, Lumen, Frontier, and other carriers serving Miami-Dade and Broward County markets are raising POTS line rates anywhere from 200% to 500% in markets where they're actively sunsetting copper infrastructure.

A POTS line that cost $45/month in 2020 may now cost $150–$250/month — and further increases are likely as carrier networks continue to retire copper. For a South Florida commercial property or condo association with 8–12 POTS lines (elevator emergency phones, fire alarm dialers, gate call boxes, fax machines), the annual cost increase can easily exceed $15,000–$20,000.

What Uses POTS Lines in a Typical South Florida Building

Most commercial and multi-family property managers are surprised to discover how many of their building's systems still rely on POTS lines. The most common are elevator emergency phones — required by ASME A17.1 and typically wired to POTS in buildings constructed before 2010; fire alarm autodialers (DACT) — required by NFPA 72 to report to a monitoring station, historically via two POTS lines; gate entry call boxes — POTS-connected systems that call a resident's phone when a visitor presses their unit number; fax lines — still present in medical office buildings and some commercial tenants; and emergency elevator lobby phones in certain high-rise buildings that require a separate POTS circuit.

Your Replacement Options by System Type

Elevator Emergency Phones: The most straightforward replacement is a cellular communicator installed in the elevator cab that uses LTE/5G rather than POTS. These units comply with ASME A17.1, cost $15–$30/month for cellular service (vs. $150–$250 for POTS), and require a one-time hardware investment of $300–$600 per elevator.

Fire Alarm Autodialers: NFPA 72-2022 has progressively reduced the requirement for DACT (dual line telephone communicators), and most modern monitoring stations now accept IP or cellular communicators as the primary path. Cellular fire alarm communicators cost $20–$40/month vs. $300–$500/month for two POTS lines, and many qualify as a "primary" communication path under current code.

Gate Entry Systems: Most modern gate entry call box manufacturers offer LTE/cellular versions of their hardware. Replacing a POTS-dependent call box with a cellular unit typically costs $500–$1,500 for hardware, plus $15–$25/month for cellular service — vs. $150–$250/month for POTS.

Acting Before the Next Rate Increase

Carriers are not required to notify customers before implementing POTS rate increases in deregulated markets. South Florida property managers who proactively migrate away from POTS now — rather than waiting for the next bill shock — lock in lower monthly costs and eliminate exposure to future increases.
