It is a switch station that consists of telephone systems and it switches connections to and from them.

 

PBX is widely used by many companies worldwide. The technology connects the company’s internal phones to an external line. It also ensures that the connection remains in place properly and ends it when a user hangs up. 

 

Practically, the main functions of a PBX are to provide one single number that external callers can use to access all employees in one company and distribute calls to employees in an even way. It also automates call answering, allows the use of customised business greetings when answering calls, and provides system call management features.

 

PBXs can be used both for VoIP and landline telephone systems. A PBX that is specifically made for VoIP is called an IP PBX, which stands for Internet Protocol Private Branch Exchange. Its benefits include manageability, scalability and enhanced features. Because IP-PBXs are more software based, they are easy to maintain and upgrading them costs less when compared to their predecessors. The most popular PBX software is Asterisk, which is a good open-source software.
