VoIP to GSM Gateway
Via TFTP Server
This is the IP address of the configured tftp server. If it is non-zero or not
blank, the IP phone will attempt to retrieve new configuration file or new code
image (update) from the specified tftp server at boot time. It will make up to 3
attempts before timeout and then it will start the boot process using the existing
code image in the Flash memory. If a tftp server is configured and a new code
image is retrieved, the new downloaded image will be verified and then saved
into the Flash memory.
Note: DO NOT interrupt the TFTP upgrade process (especially the power
supply) as this will damage the device. Depending on the network environment
this process can take up to 15 or 20 minutes.
Via HTTP Server
The URL for the HTTP server used for firmware upgrade and configuration via
HTTP. For example,
0.5.16
Here “:6688” is the specific TCP port that the HTTP server is listening at, it can
be omitted if using default port 80.
Note: If Auto Upgrade is set to “No”, VoIP Client ATA will only do HTTP
download once - at boot up.

Choose “Yes” to enable automatic HTTP upgrade and provisioning.
In “Check for new firmware every” field. Enter the number of days period.
