Grandstream • SKU GXW4104
A legacy 4-port FXO gateway for connecting analogue PSTN lines to a compatible SIP/IP PBX environment.
The GXW4104 converts 4 analogue FXO trunk lines into SIP connectivity for a supported hosted or on-premise IP PBX. It provides 4 RJ11 FXO ports, two 10/100 Ethernet ports, up to two SIP server profiles, independent accounts per port, caller-ID support, T.38 fax, SRTP and PSTN failover on power loss. This is a legacy gateway, so service-provider and lifecycle checks are essential.
Quick answer: Choose GXW4104 only when the project needs 4 analogue PSTN/FXO lines connected to a compatible SIP platform. It is not an FXS gateway for analogue phones, and it is not a modern NBN voice service by itself.
Bring up to 4 supported PSTN/FXO lines into an IP-PBX workflow.
Use independent accounts per FXO port with up to two SIP server profiles.
Use T.38 fax and the listed PSTN failover behaviour within a correctly designed legacy deployment.
A quick fit check for Australian businesses comparing equipment for users, rooms, sites or wider projects.
