Retrieve config files from TXX phones

[lacava]

Hello everyone,

I have some t2X and t4X yealink phones.
With the latest firmware, I have upgraded all of them. I did it from provisioning.
With this new firmware, we can get all config files from phone from the web interface.
In a backup purpose, I need to get this config files from the phone with a script.
I need to know where this config files are stored, if they are, in the phone to retrieve them from a script.

Thanks for your help.
