Chapter 3 - Initial System Configuration

8.In the Settings dialog box, Click Next. The DNS Settings dialog box opens.

For H.323 conferencing, DNS can be used for gatekeeper discovery using the gatekeeper host name. Using NAT Traversal, the DNS is queried for the NAT server IP address used for allocating the public (external) IP addresses to the cards for the conferencing session.

For SIP conferencing, domain names are required and therefore it is recommended to enter the details of the DNS server and the local domain name. The DNS is also used if SIP Server discovery is applied. The system decides whether to use the DHCP or the DNS server for auto-discovery with preference to the DNS server.
