FXS gateways allow conventional PSTN phones and PBX to be connected to a VoIP phone system. Conversely, FXO Gateways allow VoIP phones and PBX to be connected to a conventional PSTN phone system. FXO and FXS gateways can also be combined in a number of different ways to connect remote PSTN phone systems using VoIP.

All of the gateways we sell support the SIP protocol for establishing VoIP connections. Other protocols are available.
