Fanvil X4U Advanced 12-Line IP Phone for Businesses

The Fanvil X4U is an exceptional 12-Line IP phone designed to provide robust telecommunication solutions for businesses. This device boasts a high-resolution colour display of 2.8-inches to provide a clear and comprehensive interface. The screen also supports four lines of contextual soft keys that aim to simplify navigation and make the phone more user-friendly. Equipped with 12 SIP lines, the Fanvil X4U supports 3-way conference calling, effectively enabling multi-participant conversations.

One of the most outstanding features of this device is its high-definition voice quality. With its wideband acoustic codec G.722, the X4U ensures top-tier audio quality, thereby facilitating clear, crisp, and noise-free communication. The 12-Line Phone also possesses dual Gigabit ports which ensure high-speed data transfer.

Additional functionalities such as EHS headset connectivity and WiFi via a separate dongle enhance its user-friendly attributes. The EHS (Electronic Hook Switch) allows users to answer and end calls directly from their headsets, eliminating the need for unnecessary physical contact with the device. The product also integrates with other standard-based IP PBX systems and soft switches, demonstrating a versatile compatibility range. It supports LDAP/ XML phonebooks and allows VPN connectivity for secure remote working situations.
