 As soon as the two endpoints of the media connection are known, the system sends out an empty UDP packet to the received media address (c and m-line in received SDP data) to open a NAT/firewall binding. This empty packet also triggers the ITSP’s media gateway to start sending payload (if in “symmetric response routing” mode).

 '''Example 2: Outgoing INVITE with usage of STUN'''
-With STUN the public IP and port can be learned with a STUN Binding Request. These addresses are then inserted in SIP header and SDP body by the telephonie system.

 The STUN component does a NAT type detection and if the result shows that STUN can be used and needs to be used it is switched on, otherwise off.
-In Tabelle 1 the green modes use STUN. For the red mode (symmetric UDP) STUN cannot be used, the grey modes do not need STUN, so STUN is switched off for these NAT types in AUTO mode.

 Turning STUN off solved that problem (the ALG then worked fine), but only for one call: If a second call was started simultanously the ALG mixed up RTP ports and was signaling the RTP port of the first call in the second one.

-Such problems can only be found with a detailed look at network traces (e.g. with wireshark), so we strongly recommend to switch of ALG functionality in the router, especially in cheap "home routers".
