VoIP (Voice over Internet Protocol) is a wireless telephony system in which the calls are connected through the Internet network. When you make a call through VoIP, voice information is converted into individual network packets. These countless packets travel across the Internet to reach their destination.

Although VoIP has revolutionized communication around the world, it is not considered a viable option for audio conferences. One major challenge with packet-switched telephony is that when the data is transmitted, individual packets take different paths. These packets should ideally arrive at the destination within a specific timeframe to be assembled for audio conversion. And in such a case, even a minor glitch could end up in data loss, often leading to poor audio quality, echoes, and other noises.

PSTN vs VOIP Audio Conferencing:

PSTN (Public Switched Telephone Network) is a traditional telephony system, which is also referred to as Plain Old Telephone System (POTS). It works through circuit switches and dedicated lines. When you make a phone call via PSTN, your voice is carried on dedicated circuits as analog voice data. These circuits are constructed using copper wires. However, the advent of fiber optics has helped digitize and expedite the process extensively.

Reliability has been and always will be the kingmaker. And, one such highly reliable audio conferencing services that leverages PSTN to ensure superb audio quality is grptalk. Although it is an app-based conferencing solution, grptalk doesn’t need the Internet to make calls. This freedom lets enterprises hold on to traditional telephony systems while adapting to the modern method of using a mobile application for audio conferences.
