In Figure 1 there is an example for a simple VoIP call, where a caller initiates the communication (from a VoIP phone or a computer) that goes through a server. This server (that is also called PBX or Private Branch eXchange, PABX or Private Automated Branch eXchange, IP PBX or Internet Protocol PBX and SIP server or Session Initiation Protocol server) is connected to the Internet. Through the Internet, another VoIP phone can be called. The server can also connect to a PSTN (Public Switched Telephone Network) system and able to call anyone who has an analog landline phone or a cell phone.
