You do not need to tweak or configure the settings if all you want is getting simple SIP traffic through the firewall. Below settings are for //additional// functionality besides basic transparency.
-:!: **Turn off ICE, STUN, uPnP and other “tricks”** that your SIP client's try to use to get through ordinary firewalls. As the Internet Gate is SIP transparent such “tricks” are harmful and unnecessary - and might even actually stop SIP traffic from getting through the firewall!

 :!: Upstream prioritization must know the exact send capacity of your WAN/Internet connection to work properly. The physical capacity of the link may be much higher than the actual subscribed rate. Measure and enter the true upstream capacity of your Internet connection.
+===== Call Admission Control =====
+To prevent Internet Gate (or your Internet connection) from being overloaded it can deny further SIP calls if there is already too heavy load on the unit.
