In order to upgrade the software being used by the phone system, the maintainer may provide the new software on an SD card. This process can be used to copy that software to the SD card used by the system.
This process copies the software files in the \system\primary folder on an SD card inserted into the system's Optional SD card slot to the same folder on the SD card in the system's System SD card slot. The system will then be restarted using those files.

This process will restart the phone system and disconnect all currently connected calls.
•This process takes approximately 10 minutes or more and should not be interrupted once started.
