PBX is commonly known as Private Branch Exchange, program-controlled user switches, telephone switches, Group phones, etc..
PBX is one of the commonly used telephone communication management methods in the modern office, which enables the telephone manager to manage outside calls and outgoing calls. For some telephone exchanges, it is impossible to unify a strictly defined classification. Because manufacturers, habits, regions, product positioning and other factors called differently. So you do not have to deliberately pursue, in accordance with their own use requirements to purchase the appropriate equipment on it.
User switches, also known as program-controlled switches, complete telephone exchanges between the enterprise and the public telecommunications network, and the telephone, fax, modem and other functions merge. The general term ext. (extension) refers to an extension attached to the mainline. The subscriber switch is to process the call between the extensions and connect with the public switched telephone network (PSTN) through the trunk line.
The difference between the PBX and the group telephone system is that the subscriber of the group telephone system needs manual operation while the user switch automatically completes the task. The hybrid system includes the functions of the two systems mentioned above.
At first, the first advantage of the PBX was to save the consumption on the intercom: to deal with the line switching within the system, thereby reducing telephone charges. As user switches become popular, new features are added, such as smart routing, subscriber calls, dial extensions, and so on, which are not provided by telephone companies During the 1990s, a new type of PBX system was developed due to the two significant advances.
One is the rapid expansion of data networks and the widespread acceptance of packet switching by the public. Enterprise companies need data packet switching networks, the prospect of using this network for telephone switching, and the wide use of the Internet as a global data exchange system, make packet switching more attractive. All of these factors contribute to the development of VoIP PBX. (technically, there is no “exchange” this concept, but because the abbreviation PBX address used for a long time, so it will continue to use it.)
Another trend is the idea of core functions. PBX service has always been difficult for small companies because many companies believe that solving the phone is not the core function of the company itself. These considerations have led to the emergence of the concept of hosted PBX. For the installation of hosted PBX, PBX is installed on the phone vendor and managed by the vendor. All functions and calls are transmitted over the internet. What customers need is simply signing a service contract, rather than buying and maintaining expensive equipment.
