A main screen with two side screens
The X6U pairs a 4.3-inch (480×272) main colour screen with two 2.4-inch (320×240) side screens that carry the key field: 60 DSS keys plus five line keys with LEDs, so both the call and the key state stay visible.
Audio, conference and headset
HD audio runs on wideband G.722 and Opus, and the phone handles a 6-way conference on its own.
- G.722 and Opus
- 6-way conference
- Bluetooth 4.2 built in; Wi-Fi via Wi-Fi dongle
- EHS wireless headset support
Gigabit, PoE and IPv6
Two Gigabit ports with integrated PoE carry power and data on one cable, and the phone supports both IPv4 and IPv6.
An operating system, a mounting statement, dimensions, weight, colour and IP rating are not stated in the source materials for the X6U.
Where it fits on site
Senior desk with many lines
Twenty lines and five LED line keys cover a position that answers on behalf of several numbers.
Team leader position
Sixty DSS keys on the side screens show team availability while the main screen stays on the call.
Site with an IPv6 network
IPv4 and IPv6 are both supported, so the phone fits a network that has moved to IPv6.

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.
