Handle SIP desk-phone calling over a wired LAN connection or integrated Wi-Fi. The Mitel 6920w gives office users a fixed desktop telephone with a 3.5-inch color display, programmable keys, context-sensitive soft keys, Bluetooth connectivity, and dual Gigabit Ethernet ports. It fits users who require a familiar desk endpoint while retaining the option to connect where a network drop is unavailable or impractical. The color display presents call controls, directory information, feature prompts, and line status in a compact desktop format. Programmable keys provide direct access to extensions, shared lines, speed dials, and assigned calling features, while soft keys change with the active screen or call state. Bluetooth support allows wireless accessory and mobile-device integration without occupying the wired Ethernet connection. Mitel 50009435 RC identifies the 6920w configuration with built-in Wi-Fi capability. That wireless LAN function distinguishes it within the 6920 phone family for desks, temporary work areas, and office locations where cabling cannot be extended to every endpoint. Dual Gigabit Ethernet ports support a wired desktop deployment and permit a connected workstation to share the network connection. The phone uses SIP for compatibility with supported Mitel call-control environments and SIP telephony deployments.
