In preparation of the SwyxWare 12.20 release, Swyx is providing a new firmware for Yealink phones (T41S / T42S / T46S / T48S), version 188.8.131.52 as of today.
This firmware version is already available in our Firmware Information Service FIS.
This version supports now different ringtones for internal and external calls. In order to use this feature, it is mandatory to use SwyxWare 12.20, which will be released soon as well.
If you upgrade phones that have a firmware version earlier than V184.108.40.206, you must first install V220.127.116.11 before you install the newest firmware version.
Downloading the firmware and distributing to all connected Yealink phones can be simply done within the Swyx Control Center SCC. All necessary steps are described in the Swyx Online Help.
