IP PBX

An IP PBX is a VoIP based central telephone system mostly used by small and corporate companies. This technology is similar to traditional PBX switching system, the difference is that calls are routed through the Internet networks rather than PSTN or circuit switched network. 


Tips

Let me quickly define the terms mentioned above..

IP-PBX is short for 'Internet Protocol - Private Branch eXchange'

PSTN stands for Public Switched Telephone Network

VoIP is abbreviated for Voice over Internet Protocol 

You may also come across a term PABX which the 'A' is short for Automatic, nowadays vendors manufacture the devices to work automatically unlike old days manually or needed an operator to switch the calls. 

IP-PBX may come as VoIP hardware or software and can be programmed with soft-phone, sip phone and a VoIP gateway.
