24-port FXS VoIP gateway

The Grandstream GXW4232-V2 connects up to 24 analogue devices such as phones or fax machines to an IP telephony network. It is designed for businesses that need to migrate legacy extensions onto a SIP infrastructure without replacing existing handsets.

Single Gigabit Ethernet uplink

A single 10/100/1000 Mbps auto-sensing RJ45 port handles all traffic and power. Automated provisioning via TR-069 or XML configuration files reduces manual setup, though the single network link creates a solitary point of failure for the entire unit.

24 simultaneous calls with fax support

Each FXS port can handle an independent voice call and a 3-way conference, while T.38 or pass-through fax-over-IP runs concurrently on every port. The single Gigabit uplink and 24-port density mean bandwidth and processing headroom are shared across all active channels.

Questions about this item

How do I verify the gateway is working after connecting the 24 FXS ports?

Check that each FXS port registers with the SIP server, then place test calls on every port to confirm near HD audio and three-way conferencing.

What comes in the box with the GXW4232-V2 and what must I buy separately?

The gateway includes the unit with 24 FXS ports and one GigE RJ45 port; analogue phones, SIP trunk service and network cables are purchased separately.

Which version should I choose for 16 FXS versus 24 FXS capacity?

The GXW4232-V2 provides 24 FXS ports; if you need only 16 ports, select the 16-port model instead.
