Built-In NAT Router — High-performance NAT routing is built right in, protecting the network edge without needing a separate device.
Lifeline Support — If power goes out, the FXS port automatically hard-relays to an FXO port, keeping your PSTN calls running when you need them most.
T.38 Fax Over IP — Reliable fax transmission over your VoIP network, so you're not stuck running a separate analogue fax line.
Dual Gigabit Ethernet with PoE — Two GigE ports with 802.3af PoE input on one port means you can power the unit over your network cable and skip the wall adaptor if needed.
Secure & Automated Provisioning — TR-069 support and strong AES encryption with a per-unit security certificate make deployment and ongoing management straightforward and secure.
Failover SIP Server — Automatically switches to a secondary SIP server if the primary loses connection, keeping calls up without any manual intervention.
