About VVX EM50 Expansion Module (85X07AA)

The Poly VVX EM50 is a 30-key expansion module designed exclusively for the Poly VVX 450 IP phone. It's a great pick for receptionists, attendants, and power users who handle a high volume of calls and need quick access to more lines, contacts, and call functions — all from a clean, easy-to-read colour display right beside their phone.

Key Features

• 30 Programmable Keys — Configure each key as a line registration, call appearance, speed dial, direct station select, or busy lamp field (BLF) to suit your workflow.
• Dual-Colour LED Indicators — Red and green LEDs give you an at-a-glance view of line status, so you always know what's happening across your calls.
• 5" Colour Display — A large, high-resolution screen makes it easy to manage contacts and call activity without squinting or guessing.
• USB-Powered via Host Phone — Connects directly to the VVX 450 over USB and draws power from the host phone, so there's no need for a separate power supply.
• Supports Up to Two Modules — Attach a second VVX EM50 to the same VVX 450 for up to 60 additional keys when your workload demands it.
• Matching Design — Built to complement the look of the VVX 450, so your desk setup stays tidy and consistent.
