Auto Downgrade Firmware from configuration file
on firmware 36.72.0.25 and .26 can you set the configuration file to have the old firmware listed 36.72.0.1 and have the phone downgrade to that automatically? or is it upgrade only?

Will the firmware upgrade work if it have a string like ftp://userid:password@ftp.site.com/Firmw...2.0.1.rom?

or can i do tp://userid:password@ftp.site.com/Firmware/Yealink/T41P/36.72.0.1/ and have the file inside and the yealink phone will find it and use it?

or do i need to do tp://userid:password@ftp.site.com/Firmware/Yealink/T41P/36_72_0_1/36.72.0.1.rom to get it to work correctly?

RE: Auto Downgrade Firmware from configuration file
You can configure your firmware upgrade url in configuration file , then fill your configuration URL in server url for auto provisioning.
If you want upgrade firmware from webpage, just select the firmware from your computer but not from FTP address.
