The Expressway provides secure firewall traversal and line-side support for Unified CM registrations.
How does Jabber verify the identity of Expressway E?
Jabber clients must verify the identity of the Expressway-E they are connecting to by validating its server certificate. To do this, they must have the certificate authority that was used to sign the Expressway-E's server certificate in their list of trusted CAs.
What is Expressway C?
Expressway-C automatically generates non-configurable neighbor zones between itself and each discovered Unified CM node. A TCP zone is always created, and a TLS zone is created also if the Unified CM node is configured with a Cluster Security Mode (System > Enterprise Parameters > Security Parameters) of 1 (Mixed) (so that it can support devices provisioned with secure profiles). The TLS zone is configured with its TLS verify mode set to On if the Unified CM discovery had TLS verify mode enabled. This means that the Expressway-C will verify the CallManager certificate for subsequent SIP communications. Each zone is created with a name in the format 'CEtcp-<node name>' or 'CEtls-<node name>'.

VPN links, between the Expressway-C and the Unified CM services / clusters, are not supported. "Mixed" traversal connections are not supported. That is, we do not support traversal zones, or Unified Communications traversal zones, between Cisco VCS and Cisco Expressway even though it is possible to configure these zones. Explicitly, we do not support VCS Control traversal to Expressway-E, nor do we support Expressway- C traversal to VCS Expressway.
