Problem Description:
A potential issue can affect the Snom 720 during certain firmware downgrade: after the downgrade start the phone stuck without ending the procedure. Is still possible to recover the device performing a TFTP recovery.
Solution:
In order to address this issue we re-released some 8.7.3 firmware builds.
The re-released 8.7.3.x FW images are identical to ones they supersede, they are just smaller in file size by a removal of redundant files, so the build itself remains unchanged.
If you are locally hosting the Snom 720 firmware images please make sure to update your 8.7.3 fw binaries to the new re-release.
