Information

Required firmware for the support of the Yealink T5-desk phone series with SwyxWare 13.20 and higher. 

Beside the regular maintenance the firmware corrects the wrong behavior of the T5- desk phones that occurs in certain cases.

• Fixed the issue that dialing a number from a speed dial always picks the first line, even if another line is chosen
• Fixed the issue that the call was hung up if no one answered the blind transfer for 30
  seconds

Hint: The fix for the blind call transfer issue is a combined fix and is working properly only with
Swyx 13.30 and higher.

This firmware version is available on the Swyx Firmware Information Service FIS during the next 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.

Manual Download of Yealink T5-Series Firmware

In the context of a standard Swyx installation is no need for a manual download of the firmware and update of certified SIP-phone. Nevertheless there are some use cases where the manual update or the usage of a local download server make sense or is mandatory.

For that purpose you can find the download links for the firmware here:
