The HT496 can be configured via Web GUI as well as through the Configuration File through TFTP or
HTTP. “Config Server Path” is the TFTP or HTTP 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 2 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 Grandstream Device boots up or reboots, it will issue request for configuration file named
“cfgxxxxxxxxxxxx”, where “xxxxxxxxxxxx” is the MAC address of the device, i.e., “cfg000b820102ab”. The
configuration file name should be in lower cases.

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.
In addition, when the field “Check New Firmware only when F/W pre/suffix changes” is set to “Yes”, the
device will only issue firmware upgrade request if there are changes in the firmware Prefix or Postfix.

When “Automatic Upgrade” is set to “Yes”, Service Provider can use P193 (Auto Check Interval, in
minutes, default and minimum is 60 minutes) to have the devices periodically check with either Firmware
Server or Config Server, whenever they are defined. This allows the device periodically check if there are
any new changes need to be taken on a scheduled time. By defining different intervals in P193 for
different devices, Server Provider can spread the Firmware or Configuration File download in minutes to
reduce the Firmware or Provisioning Server load at any given time.
