retrieve the new image files by downloading them into the BudgeTone 200’s SRAM. 
During this stage, the BudgeTone 200’s LEDs will blink until the checking/downloading 
process is completed. Upon verification of checksum, the new code image will then be 
saved into the Flash. If TFTP fails for any reason (e.g., TFTP server is not responding, 
there are no code image files available for upgrade, or checksum test fails, etc), the 
BudgeTone 200 will stop the TFTP process and simply boot using the existing code 
image in the flash.  
 
TFTP process may take as long as 1 to 2 minutes over the Internet, or just 20+ seconds if 
it is performed on a LAN. Users are recommended to conduct TFTP upgrade in a 
controlled LAN environment if possible. For those who do not have a local TFTP server, 
Grandstream provides a NAT-friendly TFTP server on the public Internet for firmware 
upgrade. Please check the Services section of Grandstream’s Web site to obtain this 
TFTP server’s IP address. 
 
 
NOTE: 
 
•  When BudgeTone 200 boots up, it will send TFTP or HTTP request to download 
configuration files, there are two configuration files, one is “cfg.txt” and the 
other is “cfg000b82xxxxxx”, where “000b82xxxxxx” is the MAC address of the 
BudgeTone 200.   These two files are for initial automatically provisioning 
purpose only, for normal TFTP or HTTP firmware upgrade, the following error 
messages in a TFTP or HTTP server log can be ignored. 
 
   TFTP Error from [IP ADRESS] requesting cfg000b82023dd4 : File 
does not exist  
   TFTP Error from [IP ADRESS] requesting cfg.txt : File does not
