The Communicate Architecture Fundamentals within Genesys Cloud CX include various components that make up the infrastructure and operational hierarchy, such as Organization, Sites, Edge Groups, and Edges. However, "Gateway" is not a component of this hierarchy. Instead, the term might refer to external devices or services that connect different networks or protocols, which is not how Genesys Cloud CX structures its internal architecture.
