If you don’t have a PBX system — or any form of switched telephony, you probably don’t need to invest in an IP PBX when going to VoIP.
Many VoIP solutions are cloud-based, and these often minimize the need for on-premises hardware, including switched phone systems.
Is PBX a VoIP?
A Voice over Internet Protocol (VoIP) private box exchange (PBX) is a business telephone system that provides services similar to a standard PBX, but does so over a company’s LAN or WAN data network rather than through the circuit-switched networks used by the traditional Public Switched Telephone Network (PSTN).
Do you need a PBX for SIP?
An on premise PBX and SIP trunking, on the other hand, require significant upfront capital expenditure. IT staff must install on-site IP PBX servers and connect a SIP trunking service. In addition, it is often recommended that a business install separate Internet connectivity for the SIP trunking service.
What is the difference between PBX and VoIP?
