This topic describes the deployment options for the Cisco TelePresence Video Communication Server (VCS) and Cisco Expressway Series.
Cisco VCS delivers video-enabled collaboration throughout and beyond the enterprise network.
The figure illustrates a Cisco VCS deployment for video-enabled collaboration.
Cisco VCS Control provides video call and session control, registrations, and security for Cisco TelePresence endpoints.
Cisco VCS Expressway allows video traffic to traverse the firewall securely, enabling rich video communications with partners, customers, suppliers, mobile users, and teleworkers.
In a Cisco VCS deployment, video-enabled TelePresence endpoints that are located inside the enterprise network are registered with Cisco VCS Control. Cisco VCS Expressway is not needed to establish calls between endpoints within the enterprise network. When making calls to endpoints that are outside the enterprise network, Cisco VCS Expressway is recommended because it supports secure calls by using firewall traversal functionality.
The Cisco VCS Expressway is an optional extension of Cisco VCS Control.
Cisco VCS Expressway offers the following features for externally connected endpoints:
- B2B video communication: By using URI dialing, you allow B2B communication with customers, partners, and suppliers as easily and securely as you do with email messages.
- Remote Cisco Jabber Video for TelePresence users: Secure mobile access that is based on TLS allows you to make and receive calls on remote endpoints, such as Cisco Jabber Video for TelePresence (formerly known as Movi), without the need for a VPN connection.
- Teleworkers: Teleworkers can use their personal Cisco TelePresence-enabled endpoints for video-enabled communication with colleagues, customers, partners, and suppliers from their home offices.
Cisco Expressway Series Deployment
This section describes a Cisco Unified Communications Manager (Unified CM) deployment with the Cisco Expressway Series.
Cisco Expressway Series provides edge services to endpoints that register with Cisco Unified Communications Manager.
The figure illustrates a deployment of Cisco Unified CM with the Cisco Expressway Series. It includes voice, video, instant messaging, and presence collaboration features.
The Cisco Expressway Series is an advanced collaboration gateway that extends voice, video, instant messaging, and presence communications to an external network without the need for a VPN. The Cisco Expressway Series plays a big part in the Collaboration Edge solution when Cisco Unified CM is used for call processing. A deployment with Cisco Unified CM and the Cisco Expressway Series supports the following communications options:
- B2C video communication: Cisco Jabber Guest provides secure, browser-based B2C communication into the enterprise.
- B2B video communication: The Cisco Expressway Series supports secure connections to other businesses over the Internet based on URI dialing and integration of third-party communication devices.
- Remote Cisco Jabber users: By using the mobile and remote access feature of the Cisco Expressway Series, remote users can securely collaborate with each other.
Cisco Unified Communications Manager and Cisco VCS Control Interconnection
This section describes the deployment option where Cisco Unified CM and Cisco VCS Control are deployed in parallel and interconnected with each other.
Cisco Unified Communications Manager can interconnect with Cisco VCS.
The figure illustrates a Cisco VCS Control deployment that provides call processing for third-party H.323 video endpoints. Local and remote Cisco video endpoints register with Cisco Unified CM. Cisco Unified CM and Cisco VCS are interconnected so that calls are possible between all endpoints.
This scenario is not a preferred architecture for Cisco Collaboration Systems deployments, but it can be used when Cisco VCS Control is already present or when you need Cisco VCS Control to support third-party video endpoints. Cisco Unified CM provides the call-processing control for all Cisco endpoints. In the example, neither Cisco VCS Expressway nor the Cisco Expressway Series is deployed. Therefore, for secure integration of remote endpoints, a network solution, such as an IPsec VPN, is required to provide packet encryption and authentication over the Internet.
