    Hi Guys,
    I just upgrade a system to 15.5. Previous to doing that I upgraded all the Yealink -t42g phones to the latest firmware. After the install was complete I am being told that the firmware version is unsupported. I tried to dropping it back to version 29.81.0.60 and it too is saying it is unsupported. I cannot find the 29.81.0.61 version that it is saying is supported. Can anyone help? I need this done before Monday.

    Did you tey going to the phones tab, selecting said phones and clicking upgrade firmware? (Even though it would be a downgrade)

    Having the same issue with a Yealink T46G running 35.81.0.90 firmware, In addition, this phone reboots when in voicemail and the VM then shows its still connected in the active calls list.this then stays connected until I manually shut it down in the active call list !

    It won't let me run the upgrade because although it says unsupported it says it's up to date. I did try installing a lower version and then running the update. I says completed successfully but does nothing.

    Please note that the management console cannot downgrade a phone running a higher firmware than the supported one. You can only upgrade a phone.
    @kconnor
    Are your phones provisioned as local or remote? Are you using a 3CX FQDN or your own? Also are you using an internal FQDN or are you using an IP? What is included in the provisioning link under extension settings / phone provisioning?
    Note that firmware downloaded from the management console is stored in folder
    C:\ProgramData\3CX\Instance1\Data\Http\Interface\provisioning\xxxxxxxxxx\firmware_new\yealink for windows and
    /var/lib/3cxpbx/Instance1/Data/Http/Interface/provisioning/xxxxxxxxxxx/firmware_new/yealink for linux
