    Dear support,

    Like u could have seen in the picture the current firmware = 52.83.0.10
    In the link u provided, 3cx supports firmware from version = 52.82.0.20

    So my firmware is newer.

    Thats's is the issue you are running newer firmware not yet supported by 3CX

    If you install 52.82.0.20 , the text will not be red

    Hi AHAutomation,
    Newer doesn't mean better.
    I think the version 83 of the Yealink phones is buggy and this is why it's not supported yet by 3CX.
    I found one issue on that version 83 where Power LED provisioning wasn't working. 82 works, but 83 not.
    I think this is the one of the reasons why the version 83 is still not supported by 3CX guys.
