If your fire alarm system, elevator phone, or security system is still running on a traditional POTS (Plain Old Telephone Service) line, you're not alone, but you may be operating on aging, unsupported infrastructure that's becoming more expensive and less reliable every year. Telecom providers across the country are phasing out copper networks, and businesses that haven't planned for the transition are already feeling the impact.
Teltek helps businesses in Maryland, DC, and Florida replace POTS lines with modern, compliant, and cost-effective alternatives, with full-scope installation, cabling, and ongoing support handled by our team.
Fire and life safety systems are mission-critical systems designed to protect people and property during emergencies. Many of these systems still rely on POTS lines to communicate — and that's where the risk lies.
Systems that commonly use POTS lines include fire alarm monitoring panels, elevator emergency phones, commercial security systems, and emergency call stations. These systems are governed by standards such as NFPA 72 and local building codes, meaning any replacement solution must meet strict compliance requirements.
Cellular-based solutions operate completely independently of copper lines. With built-in battery backup, your fire alarm and life safety systems stay connected even during power outages. Fully certified for NFPA 72 compliance.
The gold standard — cellular plus IP redundancy working together. NFPA 72 increasingly recommends or requires dual-path communication for fire alarm systems because it eliminates single points of failure and provides continuous supervision.

Unlike vendors who only sell the hardware, Teltek manages the entire replacement process from start to finish. As part of our broader business voice services and structured cabling capabilities, we handle every aspect of the transition:
Onsite Installation & Conversion — removal of legacy POTS lines, installation of replacement hardware, and end-to-end testing before we leave the site.
Cabling & Infrastructure — low voltage cabling, cleanup, and optimization of your communications infrastructure as part of the replacement process.
Network & Internet Readiness — QoS configuration and redundancy planning to ensure your replacement solution performs reliably under real-world conditions.
Infrastructure Upgrades — bandwidth improvements and hardware upgrades where needed to support your new system.
Teltek provides full education and ROI modeling before you commit to anything. We analyze your current monthly POTS line costs, project future savings, and model your return on investment so you can make a confident decision.
Most businesses discover 30–60% savings on monthly line costs after switching, with a return on investment within 12–24 months. Given that POTS line costs are only going up, the longer you wait, the more expensive the status quo becomes.
Teltek has been modernizing business telecommunications infrastructure since the 1960s. We combine voice, data, and IT expertise under one roof — meaning your POTS line replacement connects seamlessly with your existing phone systems, managed IT, and structured cabling infrastructure. One partner, full coordination, zero finger-pointing.
