Poly Polycom VVX EM50 Expansion Module (VVX 450)

The Polycom VVX EM50 Expansion Module extends the capabilities of the VVX 450 business IP phone, providing a dedicated interface for managing multiple calls, contacts and workflows. Its large 5-inch high-resolution display provides a clear visual interface with programmable line keys that can be configured for line registrations, call appearances, speed dials, direct stations and busy lamp field functions. The module connects directly to the VVX 450 and receives power and signaling from the host phone, providing a convenient plug-and-play installation. Up to two EM50 expansion modules can be connected to a single VVX 450, significantly increasing available line and monitoring capabilities. It is particularly suited to receptionists, telephone attendants, administrative staff and other users who handle multiple simultaneous calls.
