The QXFXO4 adds four additional outside PSTN lines to a corporate phone network through an Epygi QX IP PBX. It can also be used to IP-enable a legacy analog PBX by connecting the FXO ports to FXS extensions. This system is a stand-alone, SIP-compliant device that also includes a firewall, VPN capability and an Auto Attendant for two-stage dialing. Integrating this product with any QX IPPBX allows the Gateway to then be managed through the IP PBX’s GUI.
