Can I Use The Onestream Gateway To Provide PSTN or ISDN2 Connectivity For My IP PBX?

Many server based VoIP Phone Systems such as Asterisk, 3CX and Snom One need additional PSTN or ISDN VoIP Gateways in order to use analogue or ISDN2e telephone lines and these would normally be installed alongside a seperate VoIP GSM Gateway.

By using the Onestream GFX or GBRI units with an IP PBX, calls from the PBX can be routed via the GSM network using the built in GSM Gateway, as well as being routed over PSTN (FXO) Lines or ISDN2e lines.

The Onestream GFX will also enable standard POTS Phones to be connected which means that there is an additional saving if the IP PBX user needed an FXS Extension gateway.
