Cisco Unified Communications Mobile and Remote Access is a core part of the Cisco Collaboration Edge
Architecture. It allows endpoints such as Cisco Jabber to have their registration, call control, provisioning, messaging
and presence services provided by Cisco Unified Communications Manager (Unified CM) when the endpoint is not
within the enterprise network. The Expressway provides secure firewall traversal and line-side support for Unified CM
registrations.
