Poly VVX EM50 Expansion Module for VVX 450 IP Phone

The Poly 89D32AA#ABA is an expansion module that connects to the VVX 450 IP Phone and gives you extra line capacity without forcing you to replace your existing handset. By adding a bank of programmable buttons and a display that is clear and high resolution, it lets you see who is on the line, which calls are on hold, and which contacts are available at a glance.

Setup is simple. Plug the module into the side of a VVX 450, wait a moment for the phone to recognize it, and the new keys are ready to configure. You can assign each key to a line, a speed-dial contact, or a feature such as call park. Because it draws power from the phone, there is no separate power cord to manage.

The extra visibility and one-touch control make a noticeable difference in environments where every second counts. A receptionist can greet callers faster, an executive assistant can juggle multiple schedules, and a small call center supervisor can keep an eye on several agents at once. If you already rely on the VVX 450 for its audio quality and reliability, the EM50 module extends that experience so you can stay organized during peak call times.

The design matches the style and footprint of the VVX 450, so it sits neatly alongside the phone without crowding your desk. Whether you manage a busy front desk, coordinate conference rooms, or support a distributed sales team, this easy-to-add module helps you stay in control of every call.
