Denunciative PBX
A PBX system is a telephone system, much like a typical office intranet, that resides within a business organisation. What a PBX does is that, it switches calls between each users in a business organisation on a local line while at the same time, allowing everyone to share a certain number of external phone line.
The PBX is owned and usually operated by the business organization. The telephone company would than act as a service provider or a supplier to such system. While some PBX system still uses analog technology, other PBX systems are using digital technology.
Before the coming of PBX, companies used to receive their incoming call by an operator using cords and switchboards. With the introduction of PBX in the 1960s, it is possible for employees of a certain business organization to place a call within a building or connect to an outside line without the help of an operator. Most operators of the past have been replaced by Automatic Call Distributors (ACD), which is a telephone facility that manages incoming calls, of today.
