The T4S Series brings power to the table with the popular Opus HD audio codec that is an advantage in the carrier/ITSP market. The T4S Series are future proof with higher hardware support that brings the latest hardware components to allow the phone to support future firmware generations. That way as Yealink continues to add more powerful features to the phone's firmware, you'll be able to keep up, worry free. The firmware for the T4S series allows for a unified firmware across all models (T41S, T42S, T46S, T48S) for easier and more convenient management and provisioning,
In addition, the T4S brings a faster user interface with high performance and a faster response rate. The T4S Series has an improved speakerphone and it is also hearing aid compatible (HAC) so that a person with hearing loss can hear more clearly.
The T4S Series brings major improvements at the same price of the existing T4 Series, that's a win-win.
