The call flow for a Mobile and Remote Access registered endpoint to central call control is as follows:
The endpoint registers with the Expressway-C.
The Expressway-C forwards the registration request to the Expressway-E.
The Expressway-E forwards the registration request to the Cisco UCM.
The Cisco UCM registers the endpoint.
When the endpoint places a call, the call flow is as follows:
The endpoint sends the call request to the Expressway-C.
The Expressway-C forwards the call request to the Expressway-E.
The Expressway-E forwards the call request to the Cisco UCM.
The Cisco UCM places the call.
The Expressway-C and Expressway-E are used to provide secure access to the Cisco UCM for endpoints that are not located on the corporate network. The Expressway-C is located on the corporate network, and the Expressway-E is located in the DMZ.
