Fanvil X4U IS EOL , USE X4U-V2
The Fanvil X4U is a professional dual-screen business IP phone designed for office users who need high-capacity SIP calling, programmable DSS functions, Gigabit networking, and HD voice. It combines a 2.8-inch main color display with a dedicated 2.4-inch DSS display, 12 SIP lines, up to 30 programmable DSS functions, dual Gigabit Ethernet ports, integrated PoE, and 6-way audio conferencing.
Designed for reception areas, administrative workstations, sales teams, customer-service environments, and managed VoIP deployments, the X4U supports Opus and G.722 wideband audio, EHS wireless headsets, IPv4/IPv6 networking, VLAN, QoS, VPN, centralized provisioning, and optional Wi-Fi or Bluetooth connectivity through compatible USB dongles. Its dual-screen layout keeps programmable line and BLF functions visible without taking over the primary call display.
