The QXFXO4 Gateway is a modular and cost-effective approach to adding four additional outside PSTN lines to a corporate phone network by utilizing either an Epygi QX IP PBX or a SIP-based PBX. It can also be used to IP-enable a legacy analog PBX by connecting the FXO ports to FXS extensions. The simple configuration and superb voice quality makes the QXFXO4 easy to deploy and manage.
This Gateway is SIP-compliant device that also includes a firewall, VPN capability and the Auto Attendant feature for two-stage dialing. Integration with any QX IP PBX is pure plug-and-play. If FXO ports are in short supply, you can add multiple gateways to the QX IP PBX, which recognizes each gateway automatically.
