Task 10: Configuring the Traversal Zone
The traversal zone configuration defines a connection between the VCS Control and VCS Expressway platforms. A
traversal zone connection allows firewall traversal for signaling and media between the two platforms. VCS Control is
configured with a traversal client zone. VCS Expressway 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).
Traversal zones for Unified Communications
If you need Unified Communications features like mobile and remote access or Jabber Guest, a secure traversal zone
connection must exist between VCS Control and VCS Expressway:
■ The VCS Control and VCS Expressway must be configured with a zone of type Unified Communications
traversal. This automatically configures an appropriate traversal zone (a traversal client zone when selected
on VCS Control or a traversal server zone when selected on VCS Expressway) that uses SIP TLS with TLS
verify mode set to On, and Media encryption mode set to Force encrypted.
■ Both VCSs must trust each other's server certificate. As each VCS acts both as a client and as a server you
must ensure that each VCS’s certificate is valid both as a client and as a server.
