then it will start the boot process using the existing code image in the Flash memory. If a

 

 

 

 

TFTP server is configured and a new code image is retrieved, the new downloaded

 

 

 

 

image will be verified and then saved into the Flash memory.

 

 

 

 

 

Note: Grandstream strongly recommends that the user upgrade firmware locally in a
