How it works:
A POTS-to-IP converter (or POTS extender) digitizes the analog signal and transmits it over an IP network (LAN/WAN). At the far end, another converter restores the analog signal, seamlessly extending the POTS line.
Benefits
Lower-cost: This is the most budget-friendly solution, requiring only a converter and your existing Ethernet network. No major upgrades or licenses are required, making it ideal for small businesses and organizations on a budget.
Cost-effective infrastructure reuse: Maximizing the use of your existing Ethernet LAN/WAN reduces capital and operational costs.
Simple setup: Deployment is easy. Simply connect the converter to one side of your existing POTS line and the Ethernet line to the other. No advanced configuration or IT team is required.
Flexible connectivity: Supports LANs, WANs, and even VPN tunnels, allowing you to extend POTS to remote sites without laying new copper or fiber.
Disadvantages
Network-dependent quality: If the IP network is congested or unstable, you may experience audio echo, jitter, or dropped calls if QoS is not configured.
Capacity limitations: While ideal for a few lines, scaling to tens or hundreds of channels may be impractical compared to other solutions.
