Default is 20 seconds. The interval of sending dummy UDP packet to keep
NAT "pin hole" open.
NAT IP address used in SIP/SDP message. Default is blank.
This radio button will enable HT386 to download firmware or configuration
file through either TFTP or HTTP.
This is the IP address of the configured TFTP server. If selected and it is non-
zero or not blank, the HT386 will attempt to retrieve new configuration file
or new code image 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: Please 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 a few minutes.
The URL for the HTTP server used for firmware upgrade and configuration
via HTTP. For example,
http://provisioning.mycompany.com:6688/Grandstream/1.0.5.16
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, HT386 will only do HTTP download
once at boot up.
In "Check for new firmware every" field, enter the number of days to enable
HT386 to check the server for firmware upgrade or configuration in the
defined period of days.
When set to No, HT386 will only do upgrade once at boot up.
