Grandstream GXW4224V2 FXS Gateway, 24 Analog Ports, Gigabit, GDMS Managed

Overview

The Grandstream GXW4224V2 moves 24 analogue phone lines onto an internet phone system (SIP, Session Initiation Protocol) from a single rack unit. It connects existing analogue handsets, fax machines, door or lift phones and the extension lines of an old PBX to a SIP server or office phone system (IP PBX), so a building can keep its handsets and structured cabling while the phone system changes. It suits hotels, hospitals, hostels, schools and factories with many analogue extensions.

It is the second hardware version of the GXW4200 series and adds cloud management through GDMS (Grandstream Device Management System).

Is it right for you?

• Suits a place with up to 24 analogue extensions to connect to a SIP system, in a 19-inch rack or on a desk.
• For 16, 32 or 48 extensions, the GXW4216V2, GXW4232V2 and GXW4248V2 are the other models on the same platform.
• It connects phones (FXS ports). To bring landlines into the same phone system, pair it with an HT8x1 FXO gateway such as the HT841.

Key features

• 24 RJ11 phone ports (FXS, Foreign Exchange Station) plus 1 RJ21 50-pin Telco connector, so you can wire to a patch panel instead of individual cords.
• An independent SIP account for each of the 24 ports, with 4 SIP server profiles per system.
• 24 concurrent calls (fewer when SRTP encryption is used).
• One 10/100/1000 Mbps auto-sensing RJ45 network port.
• HD voice with G.722 and Opus, plus G.711, G.723.1, G.726-32, G.729 and iLBC.
• T.38 fax relay (up to 14.4 kbps) and G.711 pass-through, 3-way conferencing per port and message-waiting lamp support.
• Secure boot, a unique certificate and random default password per unit, dual firmware images, SRTP, TLS and HTTPS.
• Backlit graphic LCD on the front for status.

What else you need

• A SIP server or IP PBX, such as a Grandstream UCM.
• A network connection for the RJ45 port.
• A mains socket for the power adapter in the box (100 to 240 V AC in, 12 V DC 5 A, 60 W maximum).
• If you wire through the RJ21 connector, an RJ21 Telco cable and patch panel or punch-down block.

Installation

Mount it in a 19-inch rack with the front brackets in the box, or stand it on a desk (440 x 185 x 44 mm, 1U, 2.60 kg). Wire the phones to the 24 RJ11 ports, or run one RJ21 cable to a patch panel.

A phone system installer should fit and configure it, since each port needs its own SIP account and the wiring usually runs through a patch panel.

Software and licences

Configure it from its web interface or provision it by TR-069, HTTP, HTTPS, TFTP, FTP, FTPS or GDMS. It works with IP PBXs, soft-switches and SIP platforms, and supports zero-configuration provisioning with the Grandstream UCM series.

Before you buy

• The power adapter and rack brackets are in the box. RJ21 Telco cables are not included for this model.
• A SIP server or IP PBX is required; the gateway does not make calls on its own.
• Package weight is 3.65 kg.
