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 file
“cfgxxxxxxxxxxxx”, where “xxxxxxxxxxxx” is the MAC address of the device, i.e., “cfg000b820102ab”. In
addition, device will also request a XML configuration file “cfgxxxxxxxxxxxx.xml”. If the download of
“cfgxxxxxxxxxxxx.xml” is not successful, the provision program will issue a request for a generic
configuration file “cfg.xml”. 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 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 selected, the device
will only issue firmware upgrade request if there are changes in the firmware Prefix or Postfix.
Managing Firmware and Configuration File Download
When “Automatic Upgrade” is set “Yes, every” the auto check will be done in the minute specified in this
field. If set to “daily at hour (0-23)”, Service Provider can use P193 (Auto Check Interval) to have the
devices do a daily check at the hour set in this field with either Firmware Server or Config Server. If set to
“weekly on day (0-6)” the auto check will be done in the day specified in this field. 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.
