Cisco Cisco TelePresence Video Communication Server Expressway
Mobile and remote access overview
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 VCS provides secure firewall traversal and line-side
support for Unified CM registrations.
