Fanvil X4U-V2 Enterprise IP Phone

The Fanvil X4U-V2 is the enhanced successor to the original Fanvil X4U, designed to deliver improved performance, expanded functionality, and longer-term compatibility for modern business communications.

Whilst both models share the same core design - featuring dual displays, multiple SIP lines, and HD audio - the V2 introduces key upgrades that make it better suited for today’s workplaces. These include support for up to 6-way audio conferencing (compared to 3-way on the X4U), updated firmware and hardware for smoother operation, and improved stability when using Bluetooth and Wi-Fi accessories.

With ongoing manufacturer support and enhanced collaboration features, the X4U-V2 is a clear step forward for businesses looking to upgrade or future-proof their desk phone setup.

Enhanced Call Management & Collaboration

The Fanvil X4U-V2 is built for efficient business communication, supporting up to 12 SIP lines to handle multiple calls and extensions with ease. A key upgrade from the Fanvil X4U is the improved 6-way audio conferencing, allowing teams to collaborate more effectively without relying on external conferencing tools. With essential features such as call transfer, forwarding, and hold, it ensures smooth day-to-day call handling in busy office environments.

Dual Display & Programmable DSS Keys

Designed for productivity, the X4U-V2 features a dual-screen setup, including a 2.8-inch main colour display and a secondary 2.4-inch screen dedicated to DSS keys. This allows users to manage contacts, monitor extensions, and access key functions quickly. With up to 30 programmable DSS keys across multiple pages, it’s ideal for receptionists and high call-volume users who need instant access to frequently used features.

HD Audio for Clear Communication

Audio quality is a standout feature, with HD voice support on both the handset and full-duplex speakerphone. The X4U-V2 supports wideband codecs such as G.722 and Opus, delivering clear, natural sound for both calls and conferences. This ensures conversations remain crisp and professional, even in demanding working environments.

Flexible Connectivity Options

The X4U-V2 offers versatile connectivity to suit modern workplaces. It includes dual Gigabit Ethernet ports with Power over Ethernet (PoE) for simple deployment, while optional Bluetooth and Wi-Fi support via USB dongles provide added flexibility. Users can also connect compatible wireless headsets using EHS support, making it easy to integrate with professional headset solutions.

Built for Modern Business Environments

With its updated hardware platform and ongoing firmware support, the X4U-V2 delivers improved stability and performance compared to its predecessor. Faster response times, enhanced compatibility with modern VoIP systems, and reliable day-to-day operation make it a future-ready choice for businesses looking to upgrade their desk phone solution.
