STUN Server is
IP address or Domain name of the STUN server.
Keep-alive interval
This parameter specifies how often the HT802 sends a blank UDP packet to the SIP
server in order to keep the ―hole‖ on the NAT open. Default is 20 seconds. Minimum
value is 20 seconds.
Use STUN to detect
network connectivity
Use STUN keep-alive to detect WAN side network problems. If keep-alive request does
not yield any response for configured number of times, the device will restart the TCP/IP
stack. If the STUN server does not respond when the device boots up, the feature is
disabled. Default setting is No.
Use DNS to detect
network connectivity
Use DNS to detect WAN side network problems. Default setting is Yes.
Telnet Server
Enable/Disable telnet server on device.
Firmware Upgrade
and Provisioning
Enables HT802 to download firmware or configuration file through either the TFTP, HTTP
or HTTPS server.
Via TFTP Server
This is the IP address of the configured TFTP server. If selected and it is non-zero or not
blank, the HT802 retrieves the new configuration file or new code image from the
specified TFTP server at boot time. After 5 attempts, the system will timeout and 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 is 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 local network, this process can take up
