6.2 Configuration File Download
Grandstream SIP Device can be configured via Web Interface as well as via Configuration File
through TFTP or HTTP. “Upgrade Server” 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.
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 configuration template of the firmware.
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.
6.3 Managing Firmware and Configuration File Download
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 Up-
grade Server. 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 Provision-
ing Server load at any given time.
