Configuring Traversal Server Ports

The VCS has specific listening ports assigned for connections with the firewall. In most cases the default ports should be used. However, you have the option to change these ports if necessary.

To configure the VCS traversal server ports:

•VCS Configuration > Border Controller > Ports

You will be taken to the Ports page.

•xConfiguration Traversal Server Media

•xConfiguration Traversal Server H.323

Configuring the VCS as a Traversal Server

Media demultiplexing RTP port
