Cisco Unified Communications Mobile and Remote Access (MRA) is 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 outside the enterprise network. The Expressway provides secure firewall traversal and line-side support for Unified CM registrations.
The MRA solution provides the following functions:
- Off-premises access: a consistent experience outside the network for Jabber and EX/MX/SX Series clients
- Security: secure business-to-business communications
- Cloud services: enterprise grade flexibility and scalable solutions providing rich Cisco Webex integration and service provider offerings
- Gateway and interoperability services: media and signaling normalization, and support for non-standard endpoints
