Expansion module POLY VVX EM50 Compatibility VVX EM50

The POLY VVX EM50 Expansion Module is an accessory designed to work with VVX EM50 phones, extending the phone's capabilities with additional programmable keys and line appearances. Its compact footprint (190 mm width, 210 mm depth, 55 mm height) allows installation next to a desk phone without occupying much space. The module connects to compatible VVX base units to provide faster call handling and easier access to frequently used functions.

Advantages

The expansion module provides more programmable buttons and line keys to help manage multiple calls and contacts directly from the desk. Its compact mechanical design ensures it fits alongside office phones without requiring significant desktop space. By adding dedicated keys, the device reduces navigation through on-screen menus and supports quicker transfer, conferencing, and speed-dial operations. The hardware is intended to integrate with VVX EM50 phones for seamless operation and consistent user experience.
