The PABX system has several / many cable connections that lead to a switchboard. That is why there is a term “branch” in the extension of PABX, since this “branch” refers to the number of connections connected to PABX. PABX tool is a sophisticated technology because it can be used as a telephone, modem and fax machine, and can be used as an internal communications tool employees in the office.
How it works PABX is that this device is actually a modem that serves as a central control station. Every time a new phone comes in, it will be routed through the control station. Because in the PABX system has been entered a certain code for each phone number in the office, or for each extension, then the incoming phone will be directed to the right destination by using the code.
Example of Use of PABX in the Office
PABX can also be programmed so that there will be auto greeting every time there is an incoming call before being directed to the destination in question. For fax function purposes, you can program the connection through the control station to a fax machine, or even to various fax destination numbers.
Modern PABX can even be programmed with a computer system to track every incoming call and outgoing phone. This system can even be arranged by anyone who can make a phone connection to a particular destination. PABX can also be used to determine unauthorized employee phone usage.
PABX can also be used as an Auto Attendant, a feature that automatically directs callers to certain destinations. This feature is especially suitable for large-scale businesses that always receive incoming calls in large numbers every day. You can also do conference calls using PABX.
Know the IP-PABX System
PABX (Private Automatic Brance Exchange) is a communication technology that regulates telephone connections between customers without having to go through the local center, and serves as a gateway in connecting to the PSTN network. Switch / Router serves to direct the data packets that come to the data network in accordance with the destination address. Conventionally there are 2 different networks of voice network (Circuit Network) and packet data network (Packet Data Network). However, along with the development of telecommunication technology, there is a technology that allows voice and facsimile communication to experience the process of packing and transmitted through a network of data packets known as Voice over Internet Protocol (VoIP) technology.
IP PABX is a combination of Switch / Router with PABX that handles VoIP. IP PABX can be used to bypass a circuit-switched telephone network using a data network, to connect to other data networks. By using converged networks that carry voice traffic (voice that has been dipakisasi) and data traffic simultaneously, IP PABX enables the development of new services, which are not yet available on traditional networks. For example the use of one central directory through various destination locations, as well as unified messaging.
