Installation and network connection

  • Connect network cable to WAN/ PoE port
  • Connect analog line to the FXO port(s)

Note: W04FXO 2020/2023 is a wall-mounted Media Gateway.

Network connection

W04FXO has two kinds of work mode: route and bridge:

  • when it is set to route mode, it works as a small router and NAT function has enabled. In this situation, WAN port is normally connected to uplink router/ switch, LAN port used to connect local computer or other network device (such as Ethernet switches, Hubs etc)
  • when it is set to bridge mode, WAN and LAN port are the same. It just works as Ethernet switch. When it set to bridge mode, you only need to configure WAN port IP address and DNS. If you set it to route mode, default LAN port IP is displayed and it can be change by users


Follow our Provisioning of Wildix devices - Admin Guide to provision the gateway.

For remote/ unreachable media gateways behind NAT/Firewall, follow our online Guide to remote provisioning.


Follow ISDN - FXO - GSM - SIP Trunk Settings Admin Guide to correctly set up the trunk parameters of the FXO gateway.

Factory reset

  • Use the paper clip or the object of the similar shape to press the Reset button
  • Keep the button pressed up to 15 seconds
