A hosted PBX system is an IP phone system that can be leased or rented on a monthly or annual basis, eliminating the need to buy expensive equipment. Instead, most of the equipment is hosted by the service provider, and all communication is routed through that provider to and from your company's site or sites.
Typically, this setup has the advantage of being very easy to predict in terms of cost of operation, and it is also easier to install and get up and running than all competing systems. A hosted PBX solution can also be cheaper to operate, but as usage and number of users increases, the cost advantages of hosted PBX systems typically disappear.

In regular telephone systems, a PBX (private branch exchange) is the switching system that manages calls between internal or local users. It also shares a number of lines that connect to the external, public phone system and parcels them out as needed to the local users.
In VoIP or IP telephony systems, the IP PBX does all this and more. It performs all the switching and connecting of VoIP calls. In many cases it does the same for regular telephone calls (in systems that can handle both kinds of phone system). It is also highly programmable and can perform advanced functions including voice menu systems, automatic call conferencing, click-to-call (click on a contact record on a PC screen to initiate a voice call), call logging and tracking and much more. Using an IP PBX system and VoIP telephone service allows an organization to combine (or converge) voice and data networks into a single system for cost-savings, simpler management and greater functionality.
