Fanvil X4U V2 Neutral
The Fanvil X4U V2 Neutral is a customizable neutral-branded business IP phone designed for professional VoIP deployments that need strong call handling, programmable keys, and Gigabit connectivity without fixed front-facing business branding. It features 12 SIP lines, a 2.8-inch main color display, a dedicated 2.4-inch DSS display, HD voice, 6-way audio conferencing, dual Gigabit Ethernet ports, and integrated PoE.
Built for offices, reception areas, sales teams, customer-service environments, MSP deployments, and private-label business communications, the X4U V2 provides up to 30 programmable DSS functions across five pages. USB expansion supports optional Fanvil Wi-Fi and Bluetooth dongles, while EHS headset compatibility, Opus audio, IPv4/IPv6 networking, centralized provisioning, and flexible desktop or wall-mounted installation make it a versatile business phone for managed SIP environments.
