NAT Setting
NAT (
Network Address Translation
) allows hosts in an organization’s private
intranet to transparently connect to hosts in the public domain. There is no need
for internal hosts to have registered Internet addresses. It is a way to translate
the internal private network IP address into a legal network IP address
technology. The NAT in the device web is limited to maintaining a connection
with the remote SIP server. The principle is to send a heartbeat message to the
remote SIP server at a set interval after the function is turned on. Otherwise,
the server may judge that the device is offline and allocate the SIP assigned to
other devices, resulting in failure to connect to it in the future. To do this
configuration on web

interface.
