Poly Edge E300 IP Desk Phone with Power Adapter

The Poly 89B51AA#ABA is an IP desk phone that gives professionals a simple way to sound clear and stay organized during calls. It is built around Poly HD Voice, so conversations feel natural and lifelike, and it uses NoiseBlockAI and Acoustic Fence to keep surrounding chatter out of the conversation. Whether you are fielding support tickets from a busy open office or joining a team meeting from a quiet home study, the phone helps everyone hear only what matters.

A 3.5-inch color display guides you through menus, contacts, and call status with bold graphics that are easy to read at a glance. The phone can handle up to 32 VoIP lines, making it a practical choice for reception areas, shared workstations, and executives who manage multiple numbers. An RGB status light lets colleagues see when you are on a call or free to talk without interrupting you.

Setup is flexible: connect through Power over Ethernet to reduce cabling, or use the included power adapter if PoE is not available. An adjustable bracket positions the phone for comfortable desktop use and can also secure it to a wall when desk space is limited. A dedicated RJ9 headset port and a USB-C connection accommodate wired or wireless headsets so you can move freely while talking.

Everyday durability matters too. The surface includes antimicrobial protection that helps the handset and keypad stay cleaner between wipe-downs. Full-duplex audio keeps both sides of the conversation flowing naturally, which is valuable during interviews, negotiations, and team discussions that require quick back-and-forth dialogue.
