Chorus Call founder, Dr. Giorgio Coraluppi, started with Compunetics in 1968 when they won the US Navy contract for control and communications equipment, employed in the AWS (Anti-Submarine Warfare) program. The original idea grew to three companies that provide hardware, software and conference services to the international markets.

Dr. Giorgio Coraluppi, founder of Compunetics, Compunetix and Chorus Call

In 1990 Compnetix was formed as a separate corporation to undertake commercial applications of unique, advanced voice and data switching and conferencing technology. Chorus Call Inc. was then started to provide teleconferencing services to the general public. Chorus Call South Africa joined the international group in 2001, and is part of 14 offices in 11 countries around the world.

The group of companies also hold four US Patents, and in 2020 Dr. Coraluppi and Compunetix was inducted into the Space Technology Hall of Fame for developing a digital system for voice switching and voice distribution to integrate into NASA infrastructure, by allowing software-enabled switching, and eliminating the need for manual switching. This technology is what went on to build the commercial Compunetix bridge hardware used globally today by almost every major conference call provider.

Chorus Call takes the guesswork out to conferencing. From team meetings to large events, we provide a solution for all situations. Every event offers secure SIP lines for higher call quality, operator assistance when you have a problem, high quality recordings available on request, and effortless booking or even just on-demand available 24/7/365.
