Figure 9: Typical call flow: signaling and media paths
■
Unified CM provides call control for both mobile and on-premises endpoints.
■
Signaling traverses the Expressway solution between the mobile endpoint and Unified CM.
■
Media traverses the Expressway solution and is relayed between endpoints directly; all media is encrypted
between the Expressway-C and the mobile endpoint.
between the Expressway-C and the mobile endpoint.
Jabber Client Connectivity Without VPN
The mobile and remote access solution supports a hybrid on-premises and cloud-based service model, providing a
consistent experience inside and outside the enterprise. It provides a secure connection for Jabber application traffic
without having to connect to the corporate network over a VPN. It is a device and operating system agnostic solution
for Cisco Jabber clients on Windows, Mac, iOS and Android platforms.

■
search the corporate directory
■
share content
■
launch a web conference
■

Configuring Mobile and Remote Access on Expressway
This section describes the steps required to enable and configure mobile and remote access features on
Expressway-C and Expressway-E, and how to discover the Unified CM servers and IM&P servers used by the service.
Expressway-C and Expressway-E, and how to discover the Unified CM servers and IM&P servers used by the service.
Installing Expressway Security Certificates and Setting Up a Secure Traversal Zone
To support Unified Communications features (such as mobile and remote access or Jabber Guest), there must be a
Unified Communications traversal zone connection between the Expressway-C and the Expressway-E. This involves:
Unified Communications traversal zone connection between the Expressway-C and the Expressway-E. This involves:
■
Installing suitable security certificates on the Expressway-C and the Expressway-E.
■
Configuring a Unified Communications traversal zone between the Expressway-C and the Expressway-E
