With 8 FXO ports, 1 FXS port, dual Gigabit ports with PoE support, and a built-in high-performance NAT router, it's a solid pick for small-to-medium businesses looking to keep their existing analog lines while making the move to VoIP — without ripping everything out and starting again.

Key Features

8 FXO + 1 FXS Port — Connect up to 8 PSTN analog lines via RJ11 FXO ports, plus one FXS port for plugging in an analog phone or fax machine directly.
Dual Gigabit Ports with PoE — Two 10/100/1000Mbps RJ45 network ports, one with 802.3af PoE-PD support, giving you flexible, cable-tidy installation options.
Built-In NAT Router — Acts as a high-performance NAT router to help protect the network edge without needing extra hardware.
Lifeline Support — In a power outage, the FXS port hard-relays to an FXO port so you can still make and receive PSTN calls when it matters most.
Supports Up to 3 SIP Profiles — Run up to 3 SIP server profiles across 8 independent FXO accounts and 1 FXS account, with automatic failover to a secondary SIP server if the primary drops out.
T.38 Fax & AES Encryption — Reliable Fax-over-IP support via T.38, backed by strong AES encryption with a per-unit security certificate to keep your calls and data protected.
