A Private Branch Exchange (PBX) system allows an organization to manage incoming and outgoing telephone calls, as well as internal communications. A PBX consists of hardware and software that connects to communications devices such as telephone adapters, hubs, switches, routers, and telephones.
What is PBX?
Modern PBXs have a variety of management features that make communication within organizations simple and effective, helping to increase productivity. Their size and complexity vary, from expensive and complicated large-scale business communication systems to basic plans hosted in the cloud for a low monthly fee. Simple home-based PBX systems offer basic features as an upgrade to existing traditional phone lines.
The functions of a PBX can be complex, but here are the essential features:
PBXs changed dramatically with the advent of IP telephony (VoIP). Newer IP-PBXs use the Internet to channel calls. IP-PBXs are generally chosen because they offer many features. With the exception of old, already installed but still working PBXs and those chosen because they are cheap, PBX systems today are mostly IP-PBXs.
