VoIP Gateway Setup

A VoIP Gateway is used to connect your normal analogue or ISDN PBX to VoIP. Similar to a VoIP Adaptor, VoIP Gateways use VoIP through your Internet connection. With analogue gateways there are two types: FXO and FXS. An FXS gateway is used to connect an analogue PBX to VoIP so that you can use it to make and receive calls through VoIP. An FXO gateway is used to connect a VoIP Phone (usually located in another geographic location) to the analogue PBX to enable remote extensions.
