Wireless where the desk needs it
The X303W puts dual-band Wi-Fi inside the chassis, so one model covers both cases: wireless deployment where there is no cable, and PoE where there is.
Four lines and six-way conferencing
The calling set matches the X303 family: 4 SIP lines on a 2.4-inch (320×240) colour screen, HD audio on G.722 and Opus, and a 6-way audio conference in which the organiser invites up to five participants. The chip is dual-core and IPv4 and IPv6 are supported.
- EHS wireless headset support
- IPv4 and IPv6 support
- Desktop or wall-mounted
- Bluetooth, an operating system, dimensions, weight, colour and IP rating are not stated in the source materials
Where it fits on site
Desk with no data point
Dual-band Wi-Fi means the phone can be placed before any cabling work is done.
Flexible office layout
The same model runs on wireless today and on PoE if a cable is added later.
Front desk without cabling
Dual-band Wi-Fi and PoE in one model, on a four-line colour-screen desk phone.

Compatibility boundaries
This model uses standard SIP and the interfaces listed in the specification table. Confirm the PBX, SIP provider or platform against those interface notes before the order; where the documentation does not state a value, the table records it as not stated rather than estimating. PoE, analog port variants, power options and card compatibility are fixed at order time.
Handover, spares and support
Extension plan, provisioning and interface language can be prepared before dispatch. Remote support continues after handover. Spare-part, warranty and service terms are confirmed in the quotation for the models and quantity ordered, so they are not printed as a single figure here.
