How to use PBX?
More specifically, the PBX consists of different hardware devices that work together to provide connectivity to the public telephone network .
Through this system, it is possible to create extensions so that each worker or department has its own “internal telephone number ” (or extension).
In reality, the person who calls the company does so by communicating with a single telephone number. A PBX has different voice input and output channels or trunks , through which people communicate with the company. From there and through the different options and menus that the PBX proposes, it will generate the route that the person must follow until their call is transferred to the corresponding extension number.
In short, the job of a traditional private telephone exchange or PBX is to unify the different extensions associated with the same number and route them until they reach the indicated location.
