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.
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
Configuration File Download
Grandstream SIP Devices can be configured via the Web Interface as well as via a Configuration File
(binary or XML) through TFTP or HTTP/HTTPS. The Config Server Path is the TFTP or HTTP/HTTPS
server path for the configuration file. It needs to be set to a valid URL, either in FQDN or IP address format.
The Config Server Path can be the 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 the "New Password" in the Web GUI->Maintenance->Web/SSH Access
page->Admin Password. For a detailed parameter list, please refer to the corresponding firmware release
configuration template.
When the HT812/HT814 boots up or reboots, it will send a request to download a file named
"cfgxxxxxxxxxxxx” followed by a configuration XML file named "cfgxxxxxxxxxxxx.xml", where
"xxxxxxxxxxxx" is the MAC address of the phone, i.e., "cfg000b820102ab" and "cfg000b820102ab.xml". If
the download of "cfgxxxxxxxxxxxx.xml" file is not successful, the provision program will download a generic
cfg.xml file. The configuration file name should be in lower case letters.
