The Yealink SIP-T58W supports the optional brand new Bluetooth handset BTH58, which provides up to 17 hours talk time and 46 hours standby time, so the user can leave the desk and continue talking, which not only provides crystal clear voice communication, but also offers flexibility for office workers. Based on Android 9.0, the Yealink SIP-T58W not only inherits the benefits of the previous generation, but is also compatible with more third-party apps, which gives users more convenience. Administrators can easily install additional Android applications to improve collaboration and productivity. The redesigned user interface of the Yealink is more fluid, business and easier to use. The Yealink SIP-T58W includes the latest version of Yealink Optimal HD voice technologies, including Yealink Noise Proof Technology, and supports the Opus codec, which helps maximise the acoustic performance of the handset, headset, and especially the phone’s hands-free kit. And its hearing aid compatible (HAC) handset helps the person with hearing loss to hear the voice clearer. Connect directly from your desk to video conferencing with the optional 5 megapixel HD CAM50. The camera parameters such as exposure, noise point, definition, white balance and field of view are better than that of the previous generation phone. As data security is one of the most important concerns, the new phones adopt Arm TrustZone technology to protect various ARM-based data and applications. By supporting the Yealink/Unify Square Device Management Platform, management, deployment and updating the T58W series can be optimized and simplified.
