Instructions for local firmware upgrade via TFTP:
1. Unzip the firmware files and put all of them in the root directory of the TFTP server.
2. Connect the PC running the TFTP server and the phone to the same LAN segment.
3. Launch the TFTP server and go to the File menu��Configure��Security to change the TFTP server's default setting from
"Receive Only" to "Transmit Only" for the firmware upgrade.
4. Start the TFTP server and configure the TFTP server in the phone's web configuration interface.
5. Configure the Firmware Server Path to the IP address of the PC.
6. Save and Apply the changes and reboot the HT801/HT802.
End users can also choose to download a free HTTP server from

Firmware and Configuration File Prefix and Postfix

Firmware Prefix and Postfix allow the device to download the firmware name with the matching Prefix and Postfix. This makes
it possible to store all of the firmware with different versions in one single directory. Similarly, Config File Prefix and Postfix
allow the 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 a
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 on the day
specified in this field. This allows the device periodically to check if there are any new changes that need to be taken at a
scheduled time. By defining different intervals in P193 for different devices, the 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, FTP/FTPS, or HTTP/HTTPS. The Config Server Path is the TFTP, FTP/FTPS, 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 on 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 HT801/HT802 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 and then download cfg<Model>.xml. The configuration file name should be in
lower case letters.
HT801/HT802 supports DHCP option 67 allowing to provide a custom name for the provisioning file. If DHCP option 67 is
used, the following file download sequence will be applied:
Step 1: cfg<MAC>
http://httpd.apache.org/ or use the Microsoft IIS web server.
