Description
Businesses with legacy analog phone lines don’t have to rip and replace everything to go VoIP. The Fanvil GA100-16T FXO VoIP Gateway gives you an easy, high-density bridge—converting up to 16 PSTN or PBX lines into reliable SIP trunks that work seamlessly with your IP PBX or softswitch platform.
IT teams and facilities managers get rock-solid performance in a slim 1U rack-mount chassis that draws under 8 W of power, so it fits right into your existing data center or comms closet without blowing the budget on extra cooling or space.
Whether you run a busy call center or manage phones across multiple branches, this gateway keeps calls clear and your network simple.
The Telecom Spot Take
Here’s the real-world win our customers see with the GA100-16T: it lets you keep using your existing analog lines while moving the heavy lifting to modern SIP. With 16 FXO ports and four full Gigabit Ethernet connections, it handles high call volumes without choking your LAN.
The built-in echo cancellation, polarity reversal detection, and T.38 fax support mean fewer dropped calls and crystal-clear faxes even on older carrier lines. Rack-mount ready, low-power, and packed with enterprise-grade management tools like SNMP, TR-069, and auto-provisioning, it’s the kind of set-it-and-forget-it solution that saves IT directors hours every month.
Perfect for growing small businesses and enterprises that need cost-effective PSTN-to-IP integration without complexity.
