Desk phones no longer auto-update firmware

[Felicia King]

I have no problems with 3CX premise hosted instances that have been in service for 4+ years and have been maintained and kept updated. On those phone systems, all the desk phone firmware updates automatically. It is like those systems still have the configuration from years ago which autoupdates desk phone firmware.

I have other 3CX premise hosted instances which are new in the last 18 months. These do not update firmware for the desk phones automatically. I have not been able to find the location in the PBX where it can be configured for automatic updates of the desk phone firmware.
I would appreciate some help on the matter.

All the desk phones are Yealink supported versions.
All the PBX instances are hosted on Debian and it is fully patched.

It might be model specific. For example, older Polycoms (like IP SP560's) grab firmware during boot from a well known path on every boot. Newer Yealinks (like T48s) don't.

So what models are doing what?

This thread explains it well: https://www.3cx.com/community/threads/yealink-t28p-automatic-firmware-update.60762/

One of the PBX which does not update the firmware on desk phones has T43U primarily.
However another PBX which does not update the firmware has T48S.
But I also have two other PBX which DO auto update firmware on T48S and T43U models.

The only diff between the PBX is that the two that work were built over 4 years ago so I believe they retain the setting from ages ago that allowed for the auto update of firmware on desk phones. I can find no such configuration in a newly installed PBX.

This is very strange because I've never known a T48S or T43U to do any sort of auto-update with 3CX. Not even a T48G. Not even back in the day of v14 (6 years ago).

Maybe someone else will chime in with some ideas.

The system has never supported such functionality for Yealink. The rom filename is always different, and the path changes in the config file when the admin deploys the new firmware via the Phones page.

It's only possible for other brands like Grandstream where the filename remains constant, but again, you would have to deploy it from the Phones page yourself using the Firmware button. Once you deploy it for your Grandstream GXP2130 for example, the rest of the phones on the same model will eventually also upgrade automatically.

Definitely not Yealink though..
