Hi, I am new to Snom desk phones and I am trying to upgrade the built-in certificate of my M300 to SHA-2.

I followed this guide: Firmware patch from SHA-1 to SHA-2 for Snom 715

My current firmware is BSV530B7 and I have successfully added the M300 to Sraps.

Configuration Server Address:https://secure-provisioning.snom.com/snomM300/
Filename:{mac}

Neither a provisioning profile, nor direct settings applied to the phone work. I tried with two profiles, one changed only the language, another changed Plug-n-Play to true.

Unfortunately, the base encounters an error when loading the provisioning file:

If I check the SSL certificate, it is still SHA-1. Did I miss something?

    Hi,

    Unfortunately I need to confirm that the Snom M300 base station doesn't support the SHA-2 algorithm, and therefore cannot even get provisioned by SRAPS.

    It only supports SHA-1 and you can only use SRAPS for redirection for this specific reason, this I am afraid is an hardware limitation so there is no way around it.

    Thank you

    Thank you for your answer.

    I am surprised that you can still buy machines this old in a new condition in retail. They should put a sticker on every box "with tech from 20 years ago inside".
