Fanvil X4U-V2 Enterprise IP Phone

3cx compatible phone banner

The Fanvil X4U V2 is an enterprise-level IP Phone with two screens. The X4U has all the necessary VoIP features plus extended features like an EHS headset, BT dongle and Wi-Fi dongle, providing the highest-quality and convenience at an affordable price.

The V2 version boasts a major improvement compared to its predecessor, the original Fanvil X4U. While the initial version only supported 3-way conference calls, the V2 now enables you to include up to 5 individuals in your call. This enhancement facilitates better collaboration and communication among team members, regardless of their geographical location.

This version also stands out from its predecessor due to its ability to function as an SBC (Session Border Controller) by integrating the SBC software into its firmware seamlessly, cementing its position as a leading player in the communication technology arena.
