What is PSTN? and How to Switch from PSTN to VoIP?

Public Switched Telephone Network (PSTN) is a telecom network that was established in the 1800s. It delivers voice communication to businesses and residents through underground cabling and other network elements.

These network elements include worldwide telephone lines, cellular networks, fiber optic cables, switching centers, and wired systems. To learn how it works, check out our video.

Although the PSTN is still considered a standard form of communication, the network has experienced a steady decline in usage. In fact, Europe plans to phase PSTN lines out by 2025, with the rest of the world following in 2030.

And these PSTN networks are being replaced by more modern solutions like VoIP.

This is because VoIP offers businesses cost savings, flexibility, mobility, scalability, and access to cloud communication features – all of which the PSTN lacks.
