Proprietary PBX systems were dominant in corporate telecommunications infrastructure throughout the 1980s-2000s in both Brazil and the USA, representing significant capital investments. The term reflects a shift in industry discussion toward open standards and cloud-based solutions, making 'proprietary PBX' sometimes used pejoratively to reference outdated or inflexible legacy systems. In Brazilian businesses, particularly in São Paulo's financial sector, many organizations are transitioning from proprietary PBX to IP-based solutions.
