Cameron Cashman
The landscape of the modern workplace is constantly evolving, and the role of high-quality communication tools cannot be overstated. With that in mind, the dynamic telecom industry has stepped up to the plate to innovate how we communicate with our co-workers, customers, and clients.
In this new and uncharted work landscape, industry leaders Polycom and Plantronics teamed up to form Poly, which has emerged as a dominant force in the telecom market. Together with HP, they're bringing a range of new and innovative communication technology to the workplace, whether in a traditional office or remote work environment.
While smartphones have undoubtedly become ubiquitous in our lives, Poly offers a unique proposition in the Poly Edge E450 desk phone, which seamlessly blends the familiarity of a traditional office phone with modern smart features.
Alongside integration with various other standard communication technologies, the Poly E450 phone bridges the gap between tradition and innovation, promising an unparalleled user experience.
Let's delve deep into the features and functionalities of the Poly Edge E450 Phone - from integrated protection to enterprise-quality sound, this phone promises to be the new standard for offices and home workspaces.

Key features and specifications

The Poly Edge E450 Phone boasts many features that redefine the modern office communication experience, not the least its exceptional enterprise-level sound quality. Three built-in technologies ensure crystal-clear audio: Poly HD Voice, Poly Acoustic Clarity, and Poly Acoustic Fence. These features facilitate full-duplex conversations with acoustic echo cancellation and background noise suppression.
Along those lines, another one of the most essential features of a phone is the built-in microphone. Microphone sensitivity is measured by frequency response, which indicates how the microphone responds to different sound levels. It helps determine the microphone's ability to capture and produce specific sound frequencies and is typically measured in Hertz (Hz).
The Poly Edge E450 has a microphone featuring a frequency response of 50 Hz to 14 kHz, catering to a broad spectrum of audio frequencies.
The Poly Edge E450 also has not one but two colour IPS panel displays. The primary display has an aspect ratio of 16:9 and measures 3.5 inches diagonally, while the secondary display, with an aspect ratio of 9:16, measures 2.4 inches diagonally. They both offer a modest resolution of 320 x 240. Additionally, the phone features a surround light status indicator and 8-line keys, providing intuitive navigation and enhanced functionality.
As you might expect, Poly has jam-packed this phone with several connectivity options: two high-speed GigE PoE Ethernet ports for LAN connections, Bluetooth 5.0 technology, and support for various WiFi protocols. Furthermore, the Poly Edge E450 Phone is compatible with an array of headsets and offers flexible connectivity options, including USB, RJ9, and Electronic Hook Switch.
The device supports Poly Zero Touch Provisioning, PolyLens, and Polycom Device Management Service for streamlined management, ensuring hassle-free setup and maintenance.
Finally, the Poly Edge E450 Phone is compact and lightweight, making it suitable for various office
setups. Its primary colour is black, adding a touch of sophistication to any workspace.
This innovative communication device comes with a one-year limited warranty. A setup sheet, LAN cable, desk stand, and a console and handset with Microban® Antimicrobial protection are included in the box.
