Four-pack high-end IP phone

This bundle contains four Fanvil X5U handsets, each supporting 16 SIP lines for multi-line business telephony. Dual Gigabit Ethernet ports with integrated PoE simplify network cabling and power delivery. Built-in Bluetooth and EHS wireless headset support suit office workers who need hands-free operation. The pack targets organisations deploying a consistent desktop phone estate.

Sustained call handling and display utility

Each unit runs a 3.5-inch 480x320-pixel main colour display and a 2.4-inch 320x240-pixel side display for continuous line-status visibility. Harman speaker output combined with wideband G.722 and Opus codecs maintains HD audio quality during long conferences. Thirty DSS keys plus four LED-lit line keys give instant access to shared lines and BLF indicators without menu navigation. IPv4 and IPv6 dual-stack operation keeps the phones reachable on modern networks.

Deployment practicalities and common issues

PoE eliminates separate power adapters, so installers only need a single Cat5e or better drop per desk. Bluetooth pairing and optional Wi-Fi dongle setup are performed through the on-screen menus, which some administrators find less scriptable than mass-provisioning via configuration files. The side display does not tilt, so glare can be an issue on brightly lit desks. EHS headset compatibility should be verified against the specific headset model before rollout.

Questions about this item

Does the 3.5-inch color display consume much power when the phone stays on all day?

The phone draws power through its dual Gigabit ports with integrated PoE, so the 3.5-inch 480x320 display runs without a separate adapter.

What network equipment must I already have for the dual Gigabit ports and PoE to work?

A PoE-capable switch or injector feeding the dual Gigabit ports is required; no separate power brick is included.

Will my older SIP trunk and analog headset still work with the 16 SIP lines and EHS wireless headset support?

The phone supports standard SIP registration across 16 lines and EHS wireless headsets, so existing trunks and compatible headsets remain usable.
