I received a Snom M700 DECT station for a firmware upgrade.
The current firmware version is "IPDECT/03.23/B0005/24-Oct-2014 13:14".
I am aware that I first need to take the intermediate step to version 355.
However, all attempts result in an error.
I have tried both the update server specified in the documentation as well as a local update via TFTP and HTTP.
Unfortunately, without success.
Thank you in advance.
