10. Check the firmware status and remove the SD card.
Note:
Upgrading via USB storage device is not supported on the GXV3370.
No Local Firmware Servers
Service providers should maintain their own firmware upgrade servers. For users who do not have a
TFTP/HTTP/HTTPS server, some free Windows version TFTP servers are available for download from:
http://www.solarwinds.com/free-tools/free-tftp-server and http://tftpd32.jounin.net/.
Please check our web site at http://www.grandstream.com/support/firmware for latest firmware.
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 GXV3370 device 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. Update the changes and reboot the GXV3370.
End users can also choose to download a free HTTP server from http://httpd.apache.org/ or use Microsoft
IIS web server.
Provisioning and 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, HTTP or 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 “Admin Password” in the Web GUI→System Settings→Security
Settings→User Info Management page. For a detailed parameter list, please refer to the corresponding
firmware release configuration template in the following link:
