Introduction

Private Branch Exchange (PBX) is a hardware or software solution that establishes the connection between the registered VoIP clients. The registration process and the connection establishment and disconnection is made by using SIP (session initiation protocol) messages.

Please be informed that PBX development support is available in Ozeki VoIP SIP SDK from version 10.0

The PBX is connected to the Internet through standard protocols like any other device or program. The SIP messages are usually send as TCP or UDP packets through the net.

The PBX can also be connected to the PSTN (public switched telephone network). This is an other way to connect the PBX to the outside world. For this purpose you only need to have a special adapter that registers to the PBX with a SIP account and from that point the PSTN network works as a single VoIP end point.
