Advanced H.323 Settings 
 
 
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 startup-menu: "My IP Address: 10.0.2.1". 
 
On  
The system will signal the configured "NAT Address" in place of its own IP-address 
within Q.931 and H.245. 
 
Auto 
The system will try to determine if the "NAT Address" or the real IP-address should 
be used within signaling. This is done to make it possible to place calls to endpoints 
on the LAN as well as endpoints on the WAN. 
 
 
NAT Address 
This must be the external/global IP-address to the router with NAT support. Packets sent to the 
router will then be routed to the system. In the router, the following ports must be routed to the 
system’s IP-address: 
 
 
Port 1720 
Port 5555-5560 
Port 2326-2365 
 
 
Please contact your TANDBERG representative for further information. 
 
RSVP  
Auto  
Resource Reservation Protocol enables the systems to request the optimal amount 
of bandwidth for the duration of an IP videoconference. 
 
Off 
Resource Reservation Protocol is switched off. 
 
 
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.  
When selecting Dynamic, the H.323 ports used are from 11000 to 65535. Once 
65535 is reached they restart again at 11000.
