Figure 2: Unified Communications: Mobile and Remote Access Third-party SIP or H.323 devices can register to the Expressway-C and, if necessary, interoperate with Unified CM-registered devices over a SIP trunk. Figure 3: 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. Configuring Mobile and Remote Access To enable Cisco Jabber users with Mobile and Remote Access functionality, set up an Mobile and Remote Access User Policy within the User Profile Configuration window of Unified Communications Manager. The Mobile and Remote Access User Policy is not required for non-Jabber endpoints. In addition, you must configure Cisco Expressway with Mobile and Remote Access.
