Summary

Swyx provides a new firmware for SwyxWare 12.4x/13.0x for Yealink T4 desk phone series (T41S / T42S / T46S / T48S), version 66.85.133.10.

Information

The firmware corrects the wrong behavior of the T4- desk phones that occurs in certain cases.

• Fixed an issue in the advanced status signaling/rich presence. After reboot or new login it could happen that the presence status on the speed dial keys was not updated immediately.
• Fixed an issue with the EXP40 expansion module. The status LEDs on the module did not light up when the module was connected to a T48S. 

This firmware version is available on the Swyx Firmware Information Service FIS during the course of this day.

Downloading the firmware and distributing to all connected Yealink phones can be simply done via the Swyx Control Center SCC. All necessary steps are described in the Swyx Online Help.
