I have been trying to find a manual on importing certificates into Snom M300 DECT base station but could not find anything except for other SNOM firmware.
I was able to Import our CA but not Device Cert (screenshot below)
When I try to upload our self-signed cert in PEM or DER formats, this error pops up (screenshot)
I have tried to import Client Cert by selecting multiple DER encoded files (i.e. cert, public key, private key)(see screenshot)
(I've made a little error on that screenshot where cert has .crt extension, but i have fixed it in my next try, which still resulted in error)
Also we tried importing single PEM encoded cert, which has CERT and KEY combined in a single file (see screenshot)
All did not work.
Does anyone know In what format are we expected to import device certificate?
Any help would be greatly appreciated!
Here i s the screenshot of a log
