Advanced H.323 Settings

NOTE

THESE SETTINGS ONLY HAVE AN EFFECT IF THEY ARE SUPPORTED BY YOUR IP INFRA STRUCTURE.

RSVP

Auto Resource Reservation Protocol enables the endpoints to request the optimal amount of bandwidth for the duration of an IP video conference.

Off Resource Reservation Protocol is switched off.

NAT

NAT, Network Address Translation, is used in small LAN’s, often home offices, when a PC and a videoconferencing system is connected to a router with NAT support. NAT support in the videoconferencing system enables proper exchange of audio/video data when connected to an external videoconferencing system (when the IP traffic goes through an NAT router).

When NAT is On, the NAT Server Address will be shown in the startup-menu: ‘My IP Address: 10.0.2.1 (NAT)’

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 codec.

In the router, the following ports must be routed to the codec’s IP-address:

Port 1720

Port 5555-5560

Port 2326-2365

Please contact your TANDBERG representative for further information.

H.323 Ports

Static When selecting static H323 ports for TCP connections the ports 5555 or 5556 will be used for Q931 and H245 respectively.

Dynamic The operating 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 firewalls consider this as a sign of attack.
