Poly Edge E300 IP Phone | PoE | Power Supply – 89B51AA#ABA

Product Overview

The Poly Edge E300 (89B51AA#ABA) is a feature-rich IP desk phone that combines Poly's renowned noise reduction technology with a modern, cutting-edge design. This versatile phone features a bright 3.5-inch color IPS LCD display (320x240 resolution) that clearly shows lines, features, contacts, and speed dials. With 8 line keys supporting up to 32 line assignments through pagination, the E300 handles multiple calls, contacts, and features efficiently—ideal for cubicle workers, call centers, and small businesses.

Enterprise-quality audio comes standard with Poly HD Voice technology delivering lifelike voice quality across handset, speakerphone, and optional headset. NoiseBlockAI removes background noise when using the speakerphone, while Acoustic Fence technology eliminates distractions when using the handset or wired headset. Full-duplex conversations with acoustic echo cancellation ensure natural, professional communication.

This bundle includes the North American power supply for flexible installation without PoE infrastructure. Accessibility features like text-to-speech, color blindness adjustments, and larger fonts ensure functional equality for all users.
