Complete Release Notes for download at the end of the article!
In preparation of the SwyxWare 12.20 release, Swyx is providing a new firmware for Yealink phones (T41S / T42S / T46S / T48S), version 18.104.22.168 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 V22.214.171.124, you must first install V126.96.36.199 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.
