    Hi All,

    I have 3CX version 15.0.60903.0. I have a large fleet of Yealink SIP-T20P phones. I’ve noticed that these models are on 3CX's “end of life” list. However, the latest firmware version that was supported was 9.73.0.60. When I try to apply this firmware version which is available from the upgrade firmware section of the 3CX management page, it does not apply. Also, this firmware version is not available from Yealink’s download support page. Does anyone know where I can get this firmware version (9.73.0.60) for the SIP-T20P phones and if I manage to get my hands on this and apply this firmware to the phones, will the phones work successfully on 3CX 15.0.60903.0?

    Hi GR8Metal,

    You can download from the management console Updates=> Phone firmware => select the needed firmware and download it.
    For windows you can find it on this location C:\ProgramData\3CX\Instance1\Data\Http\Interface\provisioning\%RandomFolder%\firmware_new\Yealink on your server
    For Linux you can find it on this location
    /var/lib/3cxpbx/Instance1/Data/Http/Interface/provisioning/%RandomFolder%/firmware_new/Yealink

    On this link you can find step by step firmware upgrade of yealink phones.
