VoIP gateways translate signals between analog, digital, or cellular endpoints and your IP network. Connect traditional phones, CCTV cameras, and more to VoIP. Use VoIP gateways for analog ports like FXO and FXS, digital ports like T1 and BRI, and mobile devices using technologies like GSM. Deploy a VoIP gateway to facilitate telephony between an IP-PBX and analog phones, or use existing PSTN lines as failover solutions.
