The Fanvil X5U is a professional black IP phone designed for corporate environments and offices where a sleek, neutral appearance is required. It features a dual-screen layout, combining a 3.5-inch main color LCD with a 480x320 resolution and a smaller 2.4-inch side screen for auxiliary information. To handle heavy call volumes, the device supports 16 SIP lines and provides 30 DSS keys alongside 4 line keys, allowing you to manage multiple connections and shortcuts efficiently. Audio quality is handled by HD technology using G.722 and Opus wideband codecs, which, combined with built-in noise reduction, ensures clear communication during important business calls. The phone supports 6-way audio conferencing and includes integrated Bluetooth 4.2 for wireless headsets, while Wi-Fi connectivity can be added via a dongle. Its plastic housing is built for stability, featuring an adjustable foot stand that can be set to 45° or 50° to suit your desk ergonomics. Technical connectivity is provided by Gigabit Ethernet ports for fast data transfer, and the unit is powered via PoE, meaning it does not include a separate power supply in the box. You can store up to 2000 contacts in the phone book and track 1000 call log entries. Additional utility features like IPv6 support, EHS headset compatibility, and auto-answer capabilities make it a reliable tool for professionals who need immediate access to communication lines.
