UDP packet to the SIP server in order to keep the “hole” on the NAT
open.

SIP Extension to notify SIP server that the unit is behind the
NAT/Firewall.
TFTP Upgrade

This is the IP address of the configured TFTP server. If it is non-zero or
not blank, the HandyTone ATA 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.

configuration via HTTP. For example,

at, it can be omitted if using default port 80.
