Yealink’s New T4S Line is Now Available

Yealink T4S Line

The good people at Yealink have revisited their already-excellent T4G line of phones and made some significant upgrades. Whether you’re looking for an affordable entry-level phone or a powerful executive model, the new T4S line offers something for everyone.

All the T4S phones sport the same great industrial design as the T4G versions, but the technology has been upgraded to provide a smoother, more responsive interface. These enhancements also position the phones for future firmware upgrades.

The new models all share a standardized firmware. End-users likely won’t notice a difference, but it will make the phones easier to deploy, and allow for a more consistent experience across the line.

Among the improvements, the T4S devices now support the popular Opus audio codec, an HD codec in heavy use throughout the industry.

A nice new feature that hasn’t got enough attention is Hearing Aid Compatibility. (HAC) Individuals with hearing loss will appreciate Yealink’s efforts to design handset that allows them to hear more clearly. The speakerphone has also been upgraded to provide even better audio quality.

Yealink has also made USB ports standard across the T4S line. The USB port allows you to add a WiFi dongle or USB compatible headset. Or you can add a Bluetooth dongle for pairing with Bluetooth headsets or smartphones.*
