Logitech MX Master 3S for Mac Wireless Mouse (Pale Gray)

The Poly 2200-48890-025 is an expansion module for the VVX 450 business IP phone that puts more call-handling power at your fingertips. By attaching it to the right side of the phone, you gain thirty extra line keys that you can assign to line registrations, call appearances, speed dials, direct station selection, or busy lamp field monitoring. The additional keys mean fewer on-screen menus and faster one-touch access to the people and features you rely on most.

Information is presented on an LCD display that measures 5 inches and shows full color at a resolution of 480 by 800 pixels. Each key is paired with an LED indicator that lights up in red or green, so you can see at a glance whether a colleague is available, on a call, or ringing. Three page-navigation buttons let you flip through up to ninety contacts or features without crowding the screen.

The module installs in seconds. Simply dock it to the VVX 450 and the phone supplies both power and signaling, so there is no need for an external power brick or extra cables. The phone automatically recognizes the attachment, and keys can be programmed through the phone interface or centrally through your provisioning system.

This expansion adds real value in environments where call traffic is heavy and speed matters. Receptionists can monitor every extension in the office, executive assistants can juggle multiple executives’ lines, and small contact centers can keep customer queues visible at all times. Anyone who spends the day transferring calls, parking calls, or checking line status will appreciate the immediate access the module provides.
