Poly VVX EM50 Expansion Module for VVX 300-600 Phones

The Poly 85X07AA is an expansion module designed specifically for the VVX 300-600 series phones. It adds a practical way to manage multiple calls and lines without switching screens or losing focus. By connecting directly to your existing Polycom phone, it offers 40 multifunction line keys that you can customize to fit your workflow, making it easier to handle high call volumes or complex communication needs.

Each key features dual-color red and green LEDs, so you can quickly see the status of each line at a glance. This visual clarity helps reduce missed calls and improves call handling efficiency, which is especially useful for receptionists, administrative staff, or anyone who needs to juggle several conversations at once. The module supports Power over Ethernet, so it draws power through the network cable, eliminating the need for extra power adapters and simplifying installation.

Its compact and durable design fits naturally alongside your VVX phone without taking up much desk space. The EM50 is built to operate reliably in typical office environments, with a temperature range that covers most indoor settings. Whether you’re managing a busy front desk or coordinating multiple departments, this expansion module helps keep your communication organized and responsive.
