Fanvil X4 Enterprise IP Phone

Fanvil X4 Enterprise IP Phone

Cramming line monitoring, speed dial, and call information onto one small display forces a genuine compromise on any desk juggling more than a couple of extensions. The Fanvil X4 solves that with a second dedicated screen, pairing its 2.8-inch main display with a 2.4-inch side display to unlock up to 30 programmable DSS keys — real, physical, one-glance capacity that a single-screen phone in this price range simply can’t match.

This is Fanvil’s dual-screen enterprise IP phone, built for business desks that have outgrown a basic single-display phone’s visibility and key access.

A Second Screen Changes What’s Actually Practical Day to Day

Most enterprise phones at this tier force a trade-off: either accept limited DSS key count, or step up significantly in price for a high-end model’s expanded key layout. The X4’s dedicated 2.4-inch side screen alongside its 2.8-inch main display removes that trade-off, delivering up to 30 DSS keys for speed dial, BLF line monitoring, and quick-access functions without requiring external expansion hardware.

Four SIP Lines Matched to Genuine Multi-Line Use

The X4 supports 4 SIP lines, giving it real capacity for handling multiple simultaneous calls or monitored extensions — enough to make the dual-screen key layout genuinely useful rather than excessive for the line count it’s managing.

Built-In Bluetooth 4.2, No Dongle Needed

Wireless headset support comes built directly into the X4 via Bluetooth 4.2, meaning users get that flexibility from day one without sourcing a separate USB adapter — a detail that matters for IT teams trying to standardize hardware without managing extra accessory SKUs.

EHS Support Rounds Out Headset Flexibility

Alongside Bluetooth, the X4 also supports EHS (Electronic Hook Switch) wired headset integration, so users who prefer a corded headset with hook-switch control aren’t left without an option.

Reliable HD Audio on the G.722 Wideband Codec

The X4 delivers HD voice quality through the G.722 wideband codec, keeping everyday business conversations clear and natural without dropouts or muddiness on typical office network conditions.

Six-Way Conferencing Built Directly Into the Phone

Team discussions and quick multi-party calls run through the X4’s built-in 6-way audio conferencing, with no separate conferencing hardware or software required to get a small group on the same call.

Choose Your Network Speed: X4 or X4G

Fanvil offers this phone in two networking configurations. The standard X4 runs 10/100Mbps Fast Ethernet, while the X4G steps up to full 10/100/1000Mbps Gigabit — letting a business match the phone to its actual network infrastructure instead of paying for Gigabit throughput on a Fast-Ethernet-only office network.

PoE Keeps Installation Simple

Power over Ethernet support means the X4 draws power straight from its network cable, cutting down on the extra adapters and cable runs that would otherwise complicate a multi-desk rollout.

A Genuinely Usable 500-Entry Phonebook

With a 500-entry local phonebook and 600-entry call log, the X4 keeps contact and call history management practical for everyday business use without feeling undersized.

Adjustable Desktop Positioning

A foot stand adjustable to 40 or 50 degrees lets each desk set the phone at whichever angle actually works best for that workspace.

Why the Dual-Screen Approach Makes Sense Here

For desks that need more than a handful of DSS keys but don’t need — or can’t justify the cost of — a high-end phone’s full expanded key layout, the X4’s dual-screen design hits a genuinely practical middle point. It’s the difference between constantly scrolling through menus to find a monitored extension and simply glancing at a dedicated key.

Perfect For

• Enterprise desks managing several monitored extensions or speed-dial contacts
• Teams that want Bluetooth headset support built in, not bolted on
• Offices choosing between Fast Ethernet and Gigabit based on actual network needs
• Businesses standardizing on PoE deployment across multiple desks
• Users who want 6-way conferencing without extra hardware
• IT teams looking for a mid-tier phone that avoids high-end pricing
