Why each option
Cisco Mobile and Remote Access (MRA) for remote users requires specific components to provide secure access to on-premises collaboration features. These components facilitate external connectivity and internal call processing for devices outside the corporate network.
Cisco Unified Border Element (CUBE) is primarily used for SIP trunking and interworking, not for Mobile and Remote Access (MRA).
Cisco Expressway-E acts as the secure edge device, allowing remote clients to traverse the firewall, while Cisco Expressway-C is the internal-facing component that communicates with Cisco Unified Communications Manager (UCM). UCM is the core call processing engine responsible for registering endpoints and handling call routing.
Cisco Video Communication Server (VCS) is an older product largely superseded by Expressway for MRA functionality.
CUBE is for SIP trunking/border control, not MRA, and VCS is outdated for this purpose.
