Overview
What it is
The Fanvil X303G is the gigabit model of the X303 colour screen SIP desk phone. It has a 2.4 inch, 320 x 240 colour display, four SIP (Session Initiation Protocol) accounts and two gigabit Ethernet ports.
What it is used for
It suits knowledge workers and admin teams whose computers connect through the phone and need full gigabit speed, plus users who monitor colleagues with BLF keys.
Key features
- Two 10/100/1000 Mbps Ethernet ports with bridged PC port
- IEEE 802.3af PoE or an optional 5 V / 0.6 A adapter, 802.3az energy-efficient Ethernet
- 4 SIP lines, 3 LED line keys, programmable DSS and BLF
- HD audio with G.722 and Opus, 6-way local conference
- RJ9 headset port with EHS wireless headset support
- IPv4/IPv6, VLAN, 802.1x and VPN
Buying considerations
The phone needs an IP PBX or hosted SIP service. Fanvil lists the adapter as optional, so PoE switch ports are the usual power source. Choose the X303P if the desk only needs 10/100 Mbps.
Installation considerations
The desk stand sets 45 or 50 degrees. The WB108 bracket, sold separately, allows wall mounting. Provision in bulk through PnP or TR-069.
Compatibility
Standard SIP lets it register with common PBX and cloud platforms. Confirm firmware support on your platform before rollout.
