The Advanced H.323 Settings only have an effect if they are supported by your IP infrastructure.
NAT
NAT, Network Address Translation, is used when a PC and a video communication system are connected to a router with NAT support. NAT support in the video communication system enables proper exchange of audio/video data when connected to an external video communication system (when the IP traffic goes through a NAT router). When NAT is On, the NAT Server Address will be shown in the

H.323 Ports
Static When selecting static H.323 ports for TCP connections the ports 5555 to 5574 will be used for Q.931 and H.245 respectively.
Dynamic The system will allocate which ports to use when opening a TCP connection. The reason for doing this is to avoid using the same ports for subsequent calls as some firewall consider this as a sign of attack.
