What is IP PBX?

An IP PBX is a private branch exchange (telephone switching system within an enterprise) that switches calls between VoIP (Voice over Internet Protocol) users on local lines while allowing all users to share a certain number of external phone lines. The typical IP PBX can also switch calls between a VoIP user and a traditional telephone user, or between two traditional telephone users in the same way that a conventional PBX does.

With a conventional PBX, separate networks are necessary for voice and data communications. One of the main advantages of an IP PBX is the fact that it employs converged data and voice networks. This means that Internet access, as well as VoIP communications and traditional telephone communications, are all possible using a single line to each user. This provides flexibility as an enterprise grows, and can also reduce long-term operation and maintenance costs.

Business VoIP
A business VoIP solution is the same as residential VoIP except that business VoIP includes a PBX and offers many more advanced features like desk to desk calling, automated attendant, managing extensions, music on hold , conference calling and much more. Business VoIP also often includes an Internet connection that routes calls over a private network which guarantees quality phone calls
