Manual of product C455HD
Editorial note
The Audiocodes C455HD stands out for its ability to provide full duplex communication, ensuring clear and efficient simultaneous exchanges. Its 5-inch touchscreen with a resolution of 1280 x 720 pixels ensures an intuitive interface and high-quality display, making navigation through menus easier. Additionally, the ability to manage up to 8 phone lines simultaneously is a major asset for professional users, who benefit from increased flexibility for their multitasking communications. Advanced features such as voice detection and echo cancellation also contribute to optimal audio quality, even in noisy environments. However, several points deserve to be highlighted. The weight of 988 g may make the phone cumbersome for mobile use or in tight spaces. Furthermore, although the touchscreen is an advantage, its 5-inch size may seem small compared to other competing models, which could limit the visual experience. The lack of advanced wireless connectivity like Wi-Fi 6 could impact performance in highly crowded environments. Finally, the lack of advanced customization features for programmable keys could restrict the phone's adaptability to the specific needs of users. In terms of robustness, the product does not have a security cable port, which could pose a security risk in certain professional environments, thus affecting user confidence. In summary, the Audiocodes C455HD is a solid choice for those looking for a phone with many features, but it may not be suitable for everyone due to its limitations in portability and customization.Score details
