Fanvil X4G Enterprise Ip Phone With 4 Sip Lines

Fanvil X4G Enterprise IP Phone With 4 SIP Lines

An office running a Gigabit network shouldn’t have its desk phones quietly capping throughput at Fast Ethernet speeds. The Fanvil X4G is the Gigabit-networked variant of Fanvil’s dual-screen enterprise phone, delivering the same 4-line calling and expanded key layout as the standard X4, matched to 10/100/1000Mbps networking so the phone itself never becomes the bottleneck on a modern office network.

This is the Gigabit Ethernet configuration of Fanvil’s X4 enterprise IP phone, built for offices running current network infrastructure and wanting their phones to keep pace with it.

Gigabit Ethernet as the Defining Difference

Where the base X4 model runs standard 10/100Mbps Fast Ethernet, the X4G steps up to full 10/100/1000Mbps Gigabit connectivity — the single defining difference between the two variants. For businesses that have already invested in Gigabit switching and cabling throughout their office, the X4G ensures the desk phone matches that infrastructure investment rather than sitting as the slowest link in the chain.

Why This Matters for PC Pass-Through Desks

Many enterprise phones, including the X4G, allow a connected computer to pass through the phone’s second Ethernet port to reach the network. On a Gigabit-networked office, running that PC connection through a Fast-Ethernet-limited phone would throttle the computer’s network speed down to match the phone — the X4G avoids that entirely, keeping both phone and connected PC running at full Gigabit speed.

Dual Color Screens for Up to 30 DSS Keys

Like the standard X4, the X4G pairs a 2.8-inch main color screen with a 2.4-inch side display, together supporting up to 30 programmable DSS keys for speed dial, BLF line monitoring, and quick-access functions — genuine dual-display capacity without requiring external expansion modules.

Four SIP Lines for Real Multi-Line Handling

The X4G supports 4 SIP lines, giving it the calling capacity to make its expanded key layout genuinely useful for desks managing several simultaneous calls or monitored extensions.

Built-In Bluetooth 4.2 for Wireless Headset Support

Wireless headset connectivity comes built directly into the X4G through Bluetooth 4.2, with no separate USB dongle required — one less accessory for IT teams to manage across a fleet of deployed phones.

EHS Wired Headset Support Included

For users who prefer a corded headset with hook-switch control, the X4G also supports EHS (Electronic Hook Switch) integration, giving genuine flexibility in headset choice.

HD Audio and Six-Way Conferencing

The X4G delivers HD voice quality via the G.722 wideband codec, with 6-way audio conferencing built directly into the phone for team discussions and quick multi-party calls without separate conferencing hardware.

PoE Support for Simplified Installation

Power over Ethernet lets the X4G draw power directly through its Gigabit network cable, keeping installation straightforward and reducing the cabling and adapters needed across a multi-desk rollout.

A Practical 500-Entry Phonebook

With a 500-entry local phonebook and 600-entry call log, the X4G handles everyday contact and call history management without feeling undersized for genuine business use.

Adjustable Desktop Positioning

A foot stand adjustable to 40 or 50 degrees lets each desk find the viewing angle that actually works for that specific workspace.

The Practical Case for Choosing X4G Over the Base X4

For any office that has already standardized on Gigabit network infrastructure, choosing the base X4’s Fast Ethernet configuration means deliberately under-provisioning the phone relative to the network it’s plugged into. The X4G removes that mismatch, at the same dual-screen, 4-line capability the X4 series is built around.

Perfect For

• Offices running Gigabit network infrastructure wanting matched phone networking speed
• Desks where a connected PC passes through the phone and needs full network throughput
• Enterprise desks managing several monitored extensions or speed-dial contacts
• Teams wanting built-in Bluetooth headset support without extra dongles
• Businesses standardizing on PoE deployment across a Gigabit-networked office
• IT departments avoiding network bottlenecks introduced by Fast-Ethernet-limited phones
