A 48-port high-density FXS gateway for retaining compatible analogue phones, fax machines and legacy PBX devices on a SIP network.

It provides 2 × 50-pin Telco connectors, one Gigabit Ethernet port, four SIP server profiles, an independent SIP account per telephone port, T.38 fax and three-way conferencing per port.
