Explanation

The traversal zone configuration defines a connection between the Expressway-C and Expressway-E platforms. A traversal zone connection allows firewall traversal for signaling and media between the two platforms. Expressway-C is configured with a traversal client zone. Expressway-E is configured with a traversal server zone. Which type of traversal zone? If your deployment is for business to business calling, use a traversal zone. If your deployment is for mobile and remote access, use a Unified Communications traversal zone (see next section). The following configuration defines how an Expressway routes calls (and other requests) to external IP addresses. An external IP address is an IP address which is not 'known' to the Expressway and therefore assumed to be a publicly routable address. Known IP addresses are addresses defined in a subzone (using a subzone membership subnet rule). All requests destined for external IP addresses, originating at the Expressway-C are routed to the Expressway using a search rule. The Expressway-E then attempts to open a connection directly to the IP address.
