Keep NAT Alive
Check to turn on the feature to regularly send empty UDP packets to SIP registrar server to keep
NAT port mapping between this terminal and the SIP registrar server. If the SIP registrar server
does NOT treat constant dummy UDP packets as denial-of-service, DOS, attack, and your
terminal is behind NAT, you may turn on this feature to keep SIP signal channel passing through
NAT after finishing registration.
To set the frequency of sending dummy UDP packets, please go to “7. SIP Settings” / “SIP
Service” / “Keep Alive Timer”.
[On] / [Off]
Toggle between enable and disable this feature. Show check symbol ‘√’
in-line if enabled!
