Mitel Superset 420 9115-500-000 2 Line x 16 Char Display Phone

In this review the Mitel Superset 420 is assessed as a practical, no-frills office phone for small business and reception use. The bottom line: the Superset 420 is best for users who need a reliable, refurbished desk phone with clear caller ID and simple line management. Our review finds the built-in LCD and the twelve button display with LCD line indicators the single biggest reason to choose this renewed unit, since it makes handling multiple calls and identifying active lines straightforward without complex programming.

Key Features

• 2 line x 16 character display: The clear LCD shows caller ID, digits dialed, and context sensitive options so users can see call details at a glance.
• 12 button display speaker: Dedicated buttons and a speaker make hands-free calling and quick feature access convenient for receptionists and desk workers.
• LCD line status indicators: Each line button includes an LCD status indicator so you can immediately tell which lines are in use or available.
• Renewed condition: Professionally inspected and tested to work and look like new, offering cost savings compared with a new phone while maintaining functionality.
• Simple call handling: The Superset 420 focuses on core telephony functions without a steep learning curve, keeping setup and daily use straightforward.

Who It's For

The Superset 420 is ideal for small offices, shared reception desks, and users on a modest budget who still require clear caller ID and visible line status. Its two-line display and twelve-button layout suit staff who handle a steady but not overwhelming volume of calls and who value physical buttons over touchscreen interfaces.

Shoppers who need advanced features such as large programmable expansions, integrated VoIP apps, or color screens should look elsewhere. Also consider newer models if you require built-in Bluetooth, Wi-Fi, or supplemental handset features not described for this unit.
