Via TFTP Server

 

This is the IP address of the configured TFTP server. If selected and it is non-zero or not

the specified TFTP server at boot time. It will make up to 3 attempts before timeout and

 

 

 

 

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

 

 

 

 

LAN environment if using TFTP to upgrade. Please do NOT interrupt the TFTP upgrade
