Fanvil X4U IP Phone

Fanvil X4U IP Phone

The Fanvil X4U IP Phone gives busy office users a dedicated screen for programmable call controls. It combines a 2.8-inch main display with a 2.4-inch side display. Therefore, line information and DSS assignments remain visually separate. The phone also supports 12 Session Initiation Protocol lines, 30 DSS assignments, dual Gigabit Ethernet, integrated PoE, HD audio, and six-way conferencing.

Product Overview

The main 2.8-inch screen displays call details, contacts, menus, and phone status. Meanwhile, the 2.4-inch side screen presents programmable DSS labels. Both colour displays use a 320 × 240-pixel resolution.

Three physical line keys align with the side screen and use multiple pages to provide up to 30 DSS assignments. Administrators can configure supported positions for lines, speed dial, Busy Lamp Field monitoring, transfer functions, or other shortcuts. Consequently, users can handle frequent call actions without memorising unlabeled keys.

The phone also includes two 10/100/1000 Mbps Ethernet ports. Its bridged PC port lets a workstation share the desk’s network point. Furthermore, integrated IEEE 802.3af PoE supports power and data delivery through one Ethernet cable.

Common Applications

The Fanvil X4U IP Phone suits receptionists, executive assistants, administrative teams, hotels, clinics, and customer service desks. The second screen helps users identify programmed actions quickly. Moreover, 12 SIP accounts support staff who handle several extensions or departments. Gigabit computer pass-through also benefits workstations where one network outlet serves both the phone and computer.

Why Choose This Product?

The X4U separates general phone navigation from programmable call control. This dual-screen layout keeps DSS labels visible while the main display shows an active call or menu. In addition, 30 DSS assignments support detailed call workflows without a separate paper label system. Gigabit pass-through, PoE, headset support, and central provisioning make the device practical for organised enterprise telephony.

Frequently Asked Questions

What information appears on the second screen?

The 2.4-inch side screen displays labels and status information for configured DSS assignments. This design keeps programmable functions visible while the main screen handles calls and menus.

Are both X4U displays touchscreens?

No. Both are colour displays, but they do not provide touch control. Users operate the phone through its physical keys, navigation controls, and soft keys.

How can three line keys provide 30 DSS assignments?

The side display supports multiple pages of programmed positions. Users switch pages to access additional assignments through the same physical controls.

Can every DSS position register a separate SIP account?

No. The phone supports 12 SIP lines. DSS positions are shortcuts that can control accounts, BLF monitoring, speed dial, or other supported functions.

Can a computer connect through the phone without losing Gigabit capability?

Yes. Both bridged Ethernet ports support 10/100/1000 Mbps. However, the upstream switch, cabling, and computer must also support Gigabit Ethernet.

Does the X4U include built-in Wi-Fi or Bluetooth?

No. Wireless functions require compatible optional USB adapters. Buyers should confirm accessory support and availability before planning wireless deployment.

Can the X4U hold a six-person conference without a separate service?

It supports a local six-way audio conference. However, call availability and network conditions can affect how participants join the discussion.

Is the X4U suitable for users who handle many extension transfers?

Yes. Administrators can assign DSS positions to BLF and transfer-related functions. The connected SIP platform must support the required extension monitoring and call features.
