Poly CCX 400 Business Media Desk Phone (Microsoft Teams)

The Poly 848Z8AA#AC3 is a business media desk phone that brings Microsoft Teams conversations to your fingertips. Its touchscreen measures 5 inches, displays rich color, and responds instantly, so you can scroll through contacts, join meetings, or check voicemail with the ease of a mobile device. A dedicated Teams button opens calls and conferences in a single tap, removing guesswork when time is tight.

Poly built this phone for environments where every word matters. Poly HD Voice reproduces speech with clarity that feels face to face, while Acoustic Fence and NoiseBlockAI work in the background to screen out office chatter, HVAC hum, or street noise. Whether you are in a private office or a busy open floor plan, callers hear you and not the room around you.

Setup stays simple. A single Gigabit Ethernet cable carries both data and power through PoE, so there is no need for a separate power brick or extra cords under the desk. A USB A port lets you plug in a headset for focused conversations or connect storage for call recording when your workflow requires it. The phone is also compatible with hearing aids, supporting an inclusive workplace.

The Poly CCX 400 adapts to the way you work. Keep it on your desk for quick access throughout the day, or mount it on the wall with an optional kit to save space in hallways, small offices, or shared areas. With support for up to 24 SIP lines, it can handle a receptionist’s call load as easily as an individual contributor’s schedule. From corporate headquarters to remote home offices, this phone offers a reliable, familiar, and streamlined way to stay connected.
