PBX or Private Branch Exchange

PBX or Private Branch Exchange is a private telephone system used in a company. This system has several outside lines which users can share for making outside phone calls. A PBX also connects the phones within the company to each other and also connects them to outside lines. Sharing line within a company means you can have a greater number of handsets compared to lines needed, thus reducing costs.

As a company you will need to purchase and install a PBX network and operate it from within the office. Unless you are very technical it is better to contact a provider to set this up in the office. Sometimes, these providers give the users some training and then leave the system to the company for their own operation. When a problem arises, customer support is usually provided by the supplier.

PBX is a system that connects telephone extensions of a company to outside public telephone network as well as to mobile networks. An IP (Internet Protocol) PBX (Private branch exchange) is a PBX that provides audio, video, and instant messaging communication through the TCP/IP protocol stack for its internal network and interconnects its internal network with the Public Switched Telephone Network (PSTN)a for telephony communication.

Originally, such systems – called private branch exchanges (PBX) – required the use of a live operator. Since almost all private branch exchanges today are automatic, the abbreviation “PBX” usually implies a “PABX”

VoIP (Voice over Internet Protocol) gateways can be combined with traditional PBX functionality enabling businesses to use their managed intranet to help reduce long distance expenses, enjoy the benefits of a single network for voice and data and advanced CTI features or be used on a pure IP system which in most cases give greater cost savings, greater mobility, and increased redundancy.

An IP-PBX can exist as a hardware object, or virtually, as a software system.

The introduction of such systems provides clients with full control over their internal and external communication. Budgets are easily allocation per user/ extension, reports can be pulled based on call duration, most numbers called, barred numbers and itemized billing per department.
