PBXs are among the most important components of a business telephone system. An office uses a PBX, which can either be a piece of hardware or a software system, to route calls within the office and to transfer outbound and inbound calls between phone lines.
PBXs have been in use for a long time, but modern PBXs look very different from their predecessors. You can now use IP PBXs (Internet Protocol PBXs) and hosted PBXs for the same results as a traditional manual PBX. Check out our comparison chart below for a look at some VoIP service providers with hosted and cloud PBX systems.
