CONFIGURATION FILE DOWNLOAD 
Grandstream SIP  Device  can be configured via Web Interface as  well  as  via  Configuration  File  through 
TFTP or HTTP/HTTPS. “Config Server Path” is the TFTP or HTTP/HTTPS server path for configuration file. 
It needs to be set to a valid URL, either in FQDN or IP address format. The “Config Server Path” can be 
same or different from the “Firmware Server Path”. 
A configuration parameter is associated with each particular field in the web configuration page. A 
parameter consists  of a Capital letter P  and  1  to 3 (Could be extended to  4  in the future) digit numeric 
numbers.    i.e.,  P2  is  associated  with  “Admin  Password”  in  the  ADVANCED  SETTINGS  page.    For  a 
detailed parameter list, please refer to the corresponding firmware release configuration template. 
When a Grandstream device boots up or reboots, it will issue a request for a configuration XML file named 
"cfgxxxxxxxxxxxx.xml" followed by a file named "cfgxxxxxxxxxxxx", where "xxxxxxxxxxxx" is the MAC 
address of the device, i.e., "cfg000b820102ab". The configuration file name should be in lower case letters.

FIRMWARE AND CONFIGURATION FILE PREFIX AND POSTFIX 
Firmware Prefix and  Postfix allows device to  download  the firmware name with the matching Prefix and 
Postfix. This makes it the possible to store ALL of the firmware with different version in one single directory. 
Similarly, Config File Prefix and Postfix allows device to download the configuration file with the matching 
Prefix and Postfix. Thus multiple configuration files for the same device can be stored in one directory.
