The T4S Series, including the Yealink SIP-T42S IP Phone and the popular Opus HD audio codec, provides a competitive advantage in the carrier/ITSP market. The T4S Series is future-proof, with higher hardware support and the latest hardware components, allowing the phone to support future firmware generations. You’ll be able to keep up as Yealink adds more powerful features to the phone’s firmware without worrying. For easier and more convenient management and provisioning, the T4S series firmware allows for unified firmware across all models (T41S, T42S, T46S, T48S). In addition, the T4S offers a faster user interface with improved performance and response time. The T4S Series has a better speakerphone and hearing aid compatible (HAC), allowing people with hearing loss to hear better.
