Using ViaVideo

ViaVideo detects more than one IP address when:

•There is more than one LAN card in your PC.

•You are using a docking station and a PCMCIA network card.

•You are connected to your network using a Virtual Private Network (VPN).

If you want to change IP addresses once ViaVideo is already running, go to the H.323 screen (System Info>Setup>H.323 Setup>H.323) and click Choose Other IP Address.

Note Choose Other IP Address is displayed in the H.323 screen only when ViaVideo detects the presence of more than one IP address at startup. If you add another IP address while ViaVideo is running, you must restart the application so that ViaVideo can detect the new IP address.

ViaVideo presents the Multiple IP Addresses screen, and you can choose which IP address you want to use.

Once you restart the ViaVideo application, ViaVideo uses the IP address you specified. This address is displayed in the System Information screen, at the bottom of the application window, and in your address book listing.
