PBX (private branch exchange) device for establishing an internal communication system using one or more main line, controlling incoming and outgoing calls
What a PBX Phone System is
PBX is used within companies and organizations, so that users can communicate
internally (within their company) and externally (with the outside world).
It allows you to have more phones ( up to 20,000 ) while calls between users are free.
Also it switches calls between individuals on local lines while allowing
all of them to share a certain number of external phone lines.
A PBX makes it possible to split a single phone line into several private lines.
This make it easy for a customer to reach anyone in an office through a single phone number.
A PBX saves the cost of requiring a main phone line for each user to the telephone company’s central office.
PBX BENEFITS AND PURPOSES
The telephone is no longer sufficient to meet the needs of institutions,
companies, banks, tourist villages or any place or institution that has
a large number of employees or a number of departments.
Also, it does not satisfy customers’ needs.
Therefore, the PBX is a natural development of the modern age; the age
of speed and competition to gain the trust of customers by providing them
with distinguished services quickly .
