Overview

What it is

The Fanvil X303W is the Wi-Fi model of the X303 colour screen SIP desk phone. It registers four SIP (Session Initiation Protocol) accounts, has a 2.4 inch, 320 x 240 colour display and connects over 2.4 GHz or 5 GHz Wi-Fi as well as Ethernet.

What it is used for

It suits offices that are being rearranged often, desks without a data point, and small businesses that want a colour screen phone on the existing wireless network.

Key features

  • Built-in Wi-Fi: 2.4 GHz 802.11 b/g/n and 5 GHz 802.11 a/n, WPA/WPA2-PSK and 802.1X EAP
  • 4 SIP lines with 3 LED line keys, programmable DSS and BLF
  • HD audio, G.722 and Opus, 6-way local conference
  • Two 10/100 Mbps Ethernet ports
  • IEEE 802.3af PoE or a 5 V / 1 A adapter
  • RJ9 headset port with EHS wireless headset support

Buying considerations

You need a SIP server or hosted VoIP account. This model is supplied with a power supply unit, which is handy when the phone runs on Wi-Fi with no PoE cable. Wi-Fi voice quality depends on access point placement.

Installation considerations

The stand sets 45 or 50 degrees. The optional WB108 bracket allows wall mounting. Configure Wi-Fi from the phone or the web portal, and use TR-069 or PnP for bulk provisioning.

Compatibility

Standard SIP support means it works with common IP PBX and cloud platforms. Pair with the WB108 bracket for wall use.
