The 2.8-inch main display runs the call interface with 3 line keys, and a 2.4-inch side display handles the DSS keys — 6 physical keys that page through to 30 DSS assignments for busy-lamp field, speed dial, and one-touch transfers. The phone supports 12 SIP lines and 6-way audio conferencing, so a small team call can start right from the desk.\u003c\/p\u003e\n\u003cp\u003eAudio is HD wideband on both the handset and the full-duplex speakerphone, with G.722 and Opus wideband codecs. Headset choices are flexible: an RJ9 headset port, EHS support for wireless headsets with the appropriate EHS cable, Bluetooth through the optional Fanvil BT20 USB dongle, and Wi-Fi through the optional WF20 USB dongle where no network drop is available.\u003c\/p\u003e\n\u003cp\u003eThe wired install is standard fleet fare: dual Gigabit Ethernet ports with integrated PoE, so power and data arrive on one cable and the second port bridges through to the desk PC. It is a standards-based SIP phone that auto-provisions via FTP\/TFTP\/HTTP\/HTTPS, DHCP Option 66, SIP PNP, and TR-069. The desk stand adjusts to 45 or 50 degrees, and the phone is wall-mountable with an optional bracket.\u003c\/p\u003e\n\u003ch3\u003eKey Specifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e12 SIP lines, 6-way audio conferencing, SIP hotspot and hot desking support\u003c\/li\u003e\n\u003cli\u003e2.8-inch 320 x 240 main color LCD plus 2.4-inch 240 x 320 DSS side color LCD\u003c\/li\u003e\n\u003cli\u003e3 line keys with LED; 6 physical DSS keys with LED, up to 30 DSS keys over 5 pages\u003c\/li\u003e\n\u003cli\u003eHD voice — handset and full-duplex speakerphone; wideband codecs G.722 and Opus, narrowband G.711a\/u, G.729A\/B and iLBC\u003c\/li\u003e\n\u003cli\u003eRJ9 handset and headset ports; EHS support (Plantronics via APD-80 cable, Jabra via Fanvil EHS20 cable — cables sold separately)\u003c\/li\u003e\n\u003cli\u003eBluetooth via optional Fanvil BT20 USB dongle and Wi-Fi via optional WF20 USB dongle (dongles sold separately); USB 2.0 port\u003c\/li\u003e\n\u003cli\u003eDual Gigabit RJ45 ports (Network + PC, bridged) with integrated PoE; DC 5V\/2A power input\u003c\/li\u003e\n\u003cli\u003eLocal phonebook up to 1,000 entries; remote phonebook (XML\/LDAP) up to 1,000 entries; call logs up to 1,000 entries\u003c\/li\u003e\n\u003cli\u003eIPv4\/IPv6, SIP over UDP\/TCP\/TLS, SRTP, 802.1x, VLAN, LLDP, QoS; auto-provisioning via FTP\/TFTP\/HTTP\/HTTPS, DHCP Option 66, SIP PNP, and TR-069\u003c\/li\u003e\n\u003cli\u003eTwo-position desktop stand (45° and 50°); wall-mountable (bracket sold separately)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eWhat's included:\u003c\/strong\u003e X4U phone, HD handset with cord, desk stand (back rack), and a 1.5 m CAT5E Ethernet cable.
