Explanation
Cisco Expressway-C (Core) and Expressway-E (Edge) together form the Cisco recommended solution for secure B2B video collaboration with external partners. Expressway-C sits inside the enterprise network and communicates with CUCM, while Expressway-E sits in the DMZ and is the external-facing component. Together they provide firewall traversal for SIP/H.323 signaling and RTP media without requiring a DMZ host or opening many inbound firewall ports. Cisco Unified Border Element (CUBE) is an SIP trunk border element for voice/SIP, not the primary solution for secure video federation with external parties. Cisco ASA and Firepower are firewalls, not collaboration session border controllers.
