What is the difference between PBX and VoIP?

PBX systems create voice signals and transfer them through the PSTN (Public Switched Telephone Network) before it is converted to voice at the receiver’s end. VoIP transfers audio to data signals, packages it and transfers it over the internet to the destination’s voice device (VoIP-enabled landline, handset, or PC) before it is decoded to voice signal for the receiver to hear it. PBX works through on-premise infrastructure, while VoIP can be on-premise or hosted.
