The main difference between PBX and VoIP is the way they connect users.
A PBX system is essentially a small telephone network that uses standard telephone lines for incoming and outgoing calls.
A VoIP system is considerably less complicated.
Do I need a PBX for VoIP?
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.
What is a PBX VoIP?
An IP PBX is a private branch exchange (telephone switching system within an enterprise) that switches calls between VoIP (voice over Internet Protocol or IP) users on local lines while allowing all users to share a certain number of external phone lines.
What is the difference between VoIP and IP telephony?
Voice and data convergence refers to sending both voice and data (such as LAN traffic) over any data network (typically an IP network, frame relay network or ATM network). IP telephony refers to any “telephone” type service carried over IP – this could include faxing. VoIP is voice over IP only.
What is a PBX provider?
A hosted PBX (or Virtual PBX) service takes the phone system out of your telecom closet and puts it “in the cloud.” In other words, hosted PBX is a VoIP-based PBX that is maintained by a service provider and allows businesses to connect to it over the public Internet.
