Summary

Enreach releases firmware V96.87.133.3 for the Yealink T5 series (T53 / T53W / T54W / T57W) for Swyx 14 and higher.

Information

Required firmware to support the Yealink T5 series with Swyx 14.20 and higher.

This version contains Swyx-specific bug fixes or features, as well as a number of general product improvements, in particular in the area of cybersecurity.

Bug fixes:

  • Fixed an issue where the German keyboard layout (umlauts ä, ö, ü, ß) was no longer available on the Yealink T57W after updating to firmware version 96.87.133.2.
  • Fixed an issue where, under certain circumstances (VLAN ID assigned via DHCP), a phone received a new IP address every 60 seconds.

Note: After updating to major version .87, a subsequent downgrade is no longer possible. This also applies to downgrading to other OEM versions.

This firmware version will be available on the Swyx Firmware Information Service (FIS) within the next few days.

Manual download of the Yealink T5 series firmware

The firmware can easily be downloaded and distributed to all connected Yealink phones via the Swyx Control Center (SCC). All required steps are described in the Swyx Online Help.

In a standard Swyx installation, manually downloading the firmware and updating a certified SIP phone is usually not necessary. However, there are a few scenarios in which a manual update or running a local download server is necessary or useful.

The firmware can be downloaded in the restricted area of the Enreach Help Center: Yealink Firmware Download
