Normally in offices the phone service provider installs its own exchange box to monitor and manage the incoming and outgoing calls. PBX is a private branch exchange, means it’s a private telephone network that can be used with in a company instead of the network of Telephony Company. The main service provider will still be the some other telephone company, but to manage all the call PBX is used as a private branch exchange.
If we go few years back, PBX were based on analogue technology but now latest PBX systems are using digital technology in which using plain old telephone service, digital signals are converted into analogue signals for outgoing calls in a local loop.
A PBX system is consists of different telephone trunk lines, a computer that manage all the calls from PBX, and a console box for human use to manage different operations.
PBX also uses a server usually Asterisk, that have all the records of incoming and outgoing calls for each telephone number. Mostly PBX is used for VoIP calls, which means Voice over Internet Protocol. To make these calls one can use any handset that is attached with a computer (Asterisk Server) or, a SIP phone can also be used to make VoIP calls. SIP phone is a software based application that is installed on your laptop or computer. This application uses different ports of the computer to use microphone and speaker and then it can be used to make the outgoing calls or to receive the incoming calls.
