Exact SKU: This page is for Mitel part number 50009443, the 6920WT Open SIP / 3PCC business IP phone.

Open SIP / 3PCC: Part 50009443 is intended for standards-based SIP deployments and compatible third-party SIP call-control platforms. This customer-facing page should identify the phone primarily as an Open SIP / 3PCC model rather than describing it generically as a MiNet phone.

6920WT vs. 6920W: The 6920WT is based on the wireless 6920w platform but adds BioCote-treated antimicrobial plastics and an easy-to-clean handset design for high-touch and shared environments.

Antimicrobial Treatment: BioCote antimicrobial treatment is intended to inhibit the growth of certain bacteria on treated phone surfaces. It does not replace standard cleaning, sanitation, hygiene, or infection-control procedures.

Color Display - Not Touchscreen: The 6920WT uses a 3.5-inch 320 × 240 QVGA color display operated with physical programmable keys, context-sensitive softkeys, and navigation controls. It does not use a touchscreen.

Programmable Keys: The phone provides six physical programmable keys. Mitel's current Open SIP product positioning lists up to 20 programmable functions through pagination, allowing users to access additional lines, speed dials, and telephony functions without requiring a larger physical key panel.

Built-In Wi-Fi: Integrated dual-band 802.11 a/b/g/n Wi-Fi allows deployment over compatible 2.4 GHz or 5 GHz wireless networks when a wired Ethernet connection is unavailable or inconvenient.

Built-In Bluetooth: Bluetooth 5.2 supports compatible wireless headsets, mobile-device integration, PCLink, MobileLink, and other supported Bluetooth accessories without requiring an external Bluetooth adapter.

PCLink: PCLink allows supported PC collaboration and conferencing audio to use the 6920WT's handset, headset, speakerphone, and microphones as a centralized communications audio device.

MobileLink: MobileLink can pair a compatible smartphone with the desk phone for supported mobile call audio, contact synchronization, and call-log integration.

Dual Gigabit Ethernet: Two Gigabit Ethernet interfaces provide network connectivity and network pass-through to a connected computer. The PC interface carries Ethernet connectivity but does not provide PoE power to the attached device.

PoE: The 6920WT supports PoE Class 3 operation. A compatible Mitel 48V local power adapter can be used when PoE is unavailable and is normally purchased separately.

USB: The powered USB 2.0 interface provides up to 500 mA for compatible USB headsets, accessories, and mobile-device charging.

Headsets: Compatible USB, Bluetooth, analog, EHS, and DHSG headsets can be used with the phone. Exact compatibility should be verified for the intended headset model.

Expansion Module: The sidecar interface supports compatible Mitel expansion accessories such as the M695 Programmable Key Module for users who require additional physical keys.

Zoom Phone: Zoom's current certified-hardware guidance states that the 6920WT uses the same firmware file and provisioning configuration as the 6920w and should be added to the Zoom portal as a 6920w when applicable.

Current SIP Documentation: Mitel's Technical Document Center currently provides Release 6.7 documentation for the 6920 / 6920w SIP platform, including Installation Guide, Quick Reference Guide, User Guide, and separate PCLink documentation. Firmware-dependent functions and menus can vary by deployed software version.

Best Fit: Mitel 6920WT 50009443 is well suited to MSPs, hosted VoIP deployments, healthcare facilities, shared offices, hybrid workers, and other Open SIP environments requiring integrated Wi-Fi, Bluetooth, HD audio, Gigabit networking, mobile integration, USB connectivity, and antimicrobial-treated phone surfaces.
