The IP PBX’s USB uses the FAT32 format. Please format the USB disk on a laptop first.
It is up to 1TB.
Yes, it does, but don't remove the USB disk when data is transferring.
Because IP PBX uses security connection (HTTPS), downloading files on Win XP is not supported.
Note all data of USB disk will be erased while resetting to the default setting.
When USB disk is inserted into IP PBX, its data will be stored on FTP server, and thus the data of USB disk will be emptied.
Regarding this detail descriptions, it is suggested to download the product FAQ and read the documentation for more understandings, thank you.
