A portion of the telephone network that dates back several decades is often called Plain Old Telephone Service, or POTS for short. In recent years, Telecommunications Service Providers have been retiring these older POTS lines, which use analog technology, but a portion of the POTS network is still in use.

Sangoma is helping customers and service providers that use these POTS lines migrate services to newer packet-based network technology using Sangoma’s Vega 60G gateway series with the assistance of specialized solution providers.

Applications for POTS Lines

What kinds of applications have used these analog telephone lines?

The best known of these services are in the familiar market space of Unified Communications, notably a wide variety of voice and facsimile applications. Since these applications are high volume, most of the attention by telephone carriers and other service providers has been on ensuring that these voice and fax services can be converted seamlessly to newer packet technologies such as the Session Initiation Protocol (SIP).

Sangoma Vega series of media gateways have often been used by customers and service providers to migrate voice and fax applications to Internet Protocol (IP) networks and the cloud. However, there are other applications that are still implemented on POTS networks. Enterprise and industrial customers also need help migrating these services to newer technology while preserving investments in existing equipment where possible.

Safety Devices and Specialty Lines – Still Widely Used

An essential class of applications that still make substantial use of POTS networks are in the areas of safety and security used for industrial applications and on enterprise premises. Examples include fire alarms, fire panels, control panels, and elevators installed on the business premises, but currently connect over analog phone lines to monitoring systems.

The monitoring systems are used to confirm that these security and safety devices are active and still functioning properly. Some experts estimate that nearly 24 million specialty lines support these types of safety devices and services. Therefore, as phone companies continue to pursue plans to retire their POTS lines, customers need to maintain these services and their related investments in equipment and monitoring systems.

Sangoma Support for Migrating POTS Services

Sangoma is collaborating with the stakeholders that currently use or support these services, which include Customers, Telecommunication Service Providers, Solutions Integrators, and SIP trunking Providers. The goal is to provide customers with effective migration plans that can help preserve the customer’s investments.

An essential product line from Sangoma, which builds a bridge from existing analog safety and security equipment to modern packet-based networks, is the Sangoma Vega 60G analog gateways*.
