Yealing T46G Firmware 28.73.0.45/8 or 28.71.0.224

Hi,

Today I stayed up late in the company to update the Firmware of the phones. Unfortunately, the Form is only showing me
28.73.0.48, I cannot chose 28.71.0.224.
We uploaded 28.73.0.48 for testing purposes, but never used it on production phones. Both rom files were uploaded using "Phone Provisioning, Manage Frimware functionality". I now deleted the 28.73.0.48 file, but it doesn't help. I can still see the firmware and only this version. I even restarted all the services after deleting the file. And I tried deleting the 28.71.0.224. and reuploading it, but I still cannot chose this version during Firmware upgrade.

So two question:
The recommended version (most recent version with 3cx support according to http://www.yealink.com/SupportDownloadfiles_detail.aspx?CateId=310&flag=142) is 28.71.0.224., right? Or is it safe/recommended to got with 28.73.0.45 or 28.73.0.45. We are on V12 latest SP, but not on V12.5 yet.
How can I make version 28.71.0.224. appear in the chose firmware dialog?

Thanks a lot

Frank

In v12+ the firmware updates within 3cx are controlled by 3cx themselves. The firmware version listed has been QC'd by Yealink and 3cx for interopability.
To use another version of firmware not listed, you need to do a manual update.

Hi Craig,

this is great news. Thanks a lot. I was a little confused, that you can upload and manage all those rom-files, but it has no effect.

Best regards.

probably left over from last version and not removed for 1 reason or another... not sure exactly.
