Fanvil X3U Pro Entry-Level Color IP Phone with 6 SIP Lines and HD Audio for Small Business

The Fanvil X3U Pro is an entry-level color screen IP phone designed to deliver enterprise-grade voice communication at an accessible price point for small to medium-sized businesses. Building on the proven X-series platform, the X3U Pro combines essential productivity features with modern usability improvements including a 2.8-inch color display, HD audio quality, and support for up to 6 simultaneous SIP lines.

With built-in support for 6-way audio conferencing, automatic noise suppression, and compatibility with mainstream VoIP platforms including Asterisk, Broadsoft, and 3CX, the X3U Pro eliminates the communication complexity that often burdens growing teams. Dual Gigabit Ethernet ports and PoE support simplify network integration, while auto-provisioning via FTP/TFTP/HTTP/HTTPS/TR-069 enables IT teams to deploy and manage multiple devices efficiently.

The X3U Pro represents a significant upgrade from the original X3U model, adding enhanced features while maintaining backward compatibility for organizations looking to standardize their desk phone fleet.
