Key Features

• 16 FXS Ports — Connect up to 16 analogue devices via RJ11 ports or the 50-pin Telco connector, with a per-port LED for quick status checks at a glance.
• Gigabit Ethernet — A single 10/100/1000Mbps auto-sensing RJ45 port keeps things running fast and reliable on your network.
• 4 SIP Server Profiles — Supports up to 4 SIP server profiles per system with an independent SIP account per port, giving you solid flexibility across different setups and providers.

• Fax Over IP — Supports simultaneous T.38 and pass-through fax-over-IP per port, so your fax machines keep working right alongside your VoIP phones.
