Figure 2 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.
