    Hi 3cx community

    I have updated the Firmware for our snom 760 phones by visiting the 3cx management console and going to the "Phones" tab and selecting Firmware->Update.

    Changes are with the LED's:
    • On an ingoing call the top-right LED is on, when the caller hangs up the LED is off (and doesn't show that a call was missed).
    • The BLF are permanent on, lighting green. Changing when an extension is busy.
    Is it possible that this is due to the installed firmware:
    Snom snom760 (Up To Date) Snom 760 FW: Maintenance release

    The maintenance release is confusing me. Is this a pre-relase version which should not be distributed by 3cx yet? I'm thinking in this direction because at the snom documentation ( it says the latest version is

    Has anyone else experienced this issue?
    Or is this expected behaviour and can I change the behaviour back? On the phones or 3cx?

    Thanks for any input.

    Hello @bellit

    Please note that this is the expected behaviour of the new firmware. This firmware is provided to us by Snom and it is for the 3CX system that is why it is not available for download on their site. To switch the Led on for missed calls navigate to the extension settings / phone provisioning and scroll down to option "Choose how to configure Power LED notifications". From that menu choose "Missed Calls"
