VoIP handsets in Australia

How have PBX business phone systems evolved?

Discover how PBX solutions have evolved, how they have transformed business communications and learn the benefits of modern PBX phone systems.

Many people in the older generation may remember the Public Switched Telephone Network or PSTN landline phones from the past—the bulky, often yellowed business phone systems that allowed businesses to communicate. While many current-generation business owners may not know about these systems, these were the first iteration of the Private Branch Exchange (PBX) systems. 


As technology has advanced, so too have the communication needs and expectations of Australian enterprises and the PSTN phones have given way to the sleeker, often cloud-based PBX systems today.


Modern PBX business phone systems blend traditional PBX functionality with internet protocols, offering greater flexibility, mobility, and advanced call management features. In addition, the emergence of cloud-based virtual and hosted PBX solutions has eliminated the need for expensive on-site hardware, making enterprise-grade phone systems accessible to businesses of all sizes—this is evident in the fact that 61% of companies in Australia have already transitioned to VoIP-based phone systems.
