Grandstream Networks GXW4224-V2 VoIP HD Gateway w/24 FXS ports V2

The Grandstream GXW4224 V2 connects up to 24 analog phones, fax machines, or intercom devices to a SIP platform, making it a clean way to move a mid-size floor of analog extensions onto VoIP. Existing handsets and fax lines keep working while call control shifts to your IP-PBX or hosted service.

An FXS gateway connects analog phones and fax machines to VoIP by providing dial tone and mapping each port to a SIP account. With 24 FXS ports and a Gigabit network interface, the GXW4224 V2 centralizes analog wiring and simplifies large analog-to-SIP migrations.
