I'm having trouble updating our office D715s.
I'm on snom715-SIP version By loading the correct link found in the service hub on the SNOM website on the fw update page (example I receive this error from the phone (photo attached).

Trying with an even newer version I get the same error. Tested with two different phones.

  1. Hi,

    Please try and jump straight to our latest firmware as you can find below Release

    If that doesn't work we may need some more logs, if you are a Snom partner please raise a ticket instead of a Community thread, or ask your Snom reseller to do so for you.

    Thank you

  2. Hello 

    As i was right, all Firmware Links was converted to HTTPS - maybe this can fix your Problem. 

    Best regards

    Thanks everyone, I solved it with the link shared by Gianmaria. The phones now update correctly.
