Challenges in POTS Lines

Plain Old Telephone Service (POTS) was the standard communication method for over 100 years. Despite its age, POTS is still widely used in critical applications like alarm systems.

You may have noticed that POTS bills are skyrocketing and maintaining these lines is becoming increasingly difficult and time-consuming. In 2019, the FCC’s POTS Lines Forbearance Order 19-72A1 officially ended support for traditional analog POTS systems. It has become one of the most challenging transition tasks for carriers and service providers.


One step further

As a leading ATA (Analog Telephone Adapter) manufacturer, Flyingvoice stays ahead with the latest innovations in ATA gateways and VoIP terminals. We aim to simplify POTS replacement by integrating our proven devices into the solution.

With a focus on POTS replacement, we recognize the need for:

-Flexible and compact solutions

-Reliable functionality

-Products that seamlessly upgrade legacy POTS lines to digital

For a compact, feature-rich solution for elevator phones, point-of-sale systems, vending machines, or any single or dual-line applications, the LM152 is your answer.


Compact, but Powerful as usual

Integrated Functionality

This compact device integrates:

-An LTE router

-Dual-port Analog Telephone Adapter

-Dual Gigabit RJ45 ports

-Battery backup to ensure uninterrupted operation


Wide Carrier Support

The LM152 supports all major carriers in the U.S., allowing you to choose from various data plans and utilize its dual SIM cards for your POTS replacement needs.


VoLTE and VoIP Capabilities

VoLTE offers a basic replacement for POTS but lacks features like FAX and modem compatibility. VoIP offers more features but needs a PBX to function properly. Now, you don’t need to consider which to implement, because LM152 will provide both of them.


The LM152’s two RJ11 ports support both VoLTE and VoIP, making it adaptable for everything from simple elevator phones to full alarm and security systems while providing reliable performance similar to PSTN.

Additional Features

The LM152 features a Gigabit WAN port that connects to your broadband and ensures automatic failover between WAN and LTE connections. This would be a crucial function to increase the robustness of your system. Additionally, the WAN port supports PoE in, making the LM152 suitable for setups that include a PoE switch.


The LM152 also has a built-in battery that provides 24-hour backup during power outages, eliminating the need for a separate, costly backup power system.

Reliable and cost-effective devices like the LM152 can help you navigate this challenging digital transition period.
