Yealink T4G Vs T4S

Today, Yealink a leading manufacturer of VoIP Phones and Unified Communications equipment released the T4S Series of IP Phones, which are the enhanced version of the previous T4G/P models.

As you can see from the image below, the T4S Series have the same elegant look you’ve come to know and love. However, the hardware in the phone has been enhanced to handle faster response on the phone’s user interface and also to support future firmware upgrades. This way as Yealink continues to add more features to the phone’s firmware, the T4S Series is equipped to handle them.

The T4S Series share the same V81 firmware across all models so that managing and provisioning the phones is easier and convenient.

In addition, and a feature that many were asking for, the new T4S Series have Opus Support, a popular High Definition (HD) audio codec that is well known and highly used in the Carrier/ITSP market. With Opus, the T4S Series is a competitive phone that features high-end speech quality.

But that is not all, the T4S also have the advantage of being Hearing Aid (HAC) Compatible. The handset makes it easy for a person who suffers from hearing loss to hear more clearly. And for users who prefer to use the speakerphone, the speaker components have been enhanced to optimize acoustic performance over the speakerphone.

Unlike its predecessors, the new T41S and T42S have a USB port for added extension capabilities such as a Wi-Fi dongle (WF40) or a USB headset. Both of these models also feature Bluetooth connectivity through the Yealink BT40 dongle so that users can pair with a Bluetooth headset or smartphone in order to synchronize calling, contacts and call history.  The T4S Series is compatible with the same accessories used with the T4 G/P models. The YHS32 Headset, the EHS36 Electronic Hookswitch, the BT40 Bluetooth dongle, the WF40 Wi-Fi dongle, and the same power adapters and wall mounts (corresponding to like models) can be used.

The best part of this new release is that the T4S models boast tons of enhancements, but at no extra cost since they have the same price point as the old T4 series.

Enhancements summarized:

• Device performance enhancement/ faster response on the phone’s user interface.
• Opus support
• Enhanced speaker performance
• Additional USB port for the T42S & T41S (USB functions available circa 1Q2017)
• Unified Firmware
• Hearing aid compatible (HAC) Handset

Although the T4S models are coming in hot, the previous versions are still available with no EOL (End of Life) plan in view. If the old models do become EOL’d, don’t worry, Yealink will continue to offer service, firmware upgrades and additional features for the T4G/P Series.
