yealink firmware updates unreliable in newest update

[dandenson]

I have a number of systems showing that yealink *.20 firmware is incompatible. I select to update the firmware and this process doesn't work reliably. If I select multiple devices, most likely they all fail to update. Sometimes even doing a single device does nothing. I don't mean the phone fails to install the update, I mean it fails to even try to update.

Anyone else seeing this? Causing me to have to manually update phones which is time consuming.

I just updated two sites from *.83.0.20 to *.83.0.55 and had no trouble doing this from the 3cx management console. This includes on-prem phones, vpn connected phones and stun connected phones. I haven't tried sbc connected phones yet though.

We are seeing the same issue on a few PBX. Trying to upgrade to T29G's to latest firmware. No issues with T48's

Sorry forgot to mention these PBX's are connected via 3CX SBC's. A mix of Windows SBC & Debian, same issues.

The problem appears to be certain phones are referencing the wrong update file. I posted about it in this thread. Appears to affect the T29 and T46 at least:
