Documentation for Enterprise Collaboration

Cisco Preferred Architecture (PA) Design Overview guides help customers and sales teams select the appropriate architecture based on an organization's business requirements; understand the products that are used within the architecture; and obtain general design best practices. These guides support sales processes.

Cisco Validated Design (CVD) guides provide detailed steps for deploying the Cisco Preferred Architectures. These guides support planning, design, and implementation of the Preferred Architectures.

Cisco Collaboration System 11.x Solution Reference Network Design (SRND) guide provides detailed design options for Cisco Collaboration. The SRND should be referenced when design requirements are outside the scope of Cisco Preferred Architectures.

About This Guide

This Cisco Validated Design guide for the Cisco Enterprise Collaboration Preferred Architecture is for:

• Sales teams that sell, design, and deploy collaboration solutions
• Customers and sales teams who want detailed design best practices and ordered steps for deploying Cisco Collaboration

Readers of this guide should have a general knowledge of Cisco voice, video, and collaboration products and a basic understanding of how to deploy these products. We recommend that readers review the Cisco Preferred Architecture for Enterprise Collaboration 11.x Design Overview before reading this CVD document.

The design decisions within this CVD are in line with the framework outlined in the Cisco Collaboration SRND. While the SRND offers many design and deployment options, in this document a single deployment recommendation is selected based on fundamental assumptions for the Preferred Architecture design. Different assumptions can certainly lead to different design decisions, which then should be validated against the SRND. For large deployments with unique needs and advanced customization, it is recommended to work with your Cisco Account Manager for guidance beyond that contained in this CVD or the SRND.

This guide simplifies the design and sales process by:

• Building upon the product and design recommendations of the Cisco Preferred Architecture for Enterprise Collaboration 11.x Design Overview
• Cisco Preferred Architecture Design Overview
• Detailing a collaboration architecture, identifying best practices, and explaining the reasoning behind those recommendations

This CVD guide is organized into the following discrete modules that integrate together to form the overall Collaboration solution:

• Call Control — Explains fundamental concepts of dial plan design, Computer Telephony Integration (CTI), Survivable Remote Site Telephony (SRST), IM and Presence, LDAP directory integration, SIP trunks, and other aspects of call control. This chapter also lists the best practices for deploying call control in the Enterprise Collaboration Preferred Architecture.
• Conferencing — Describes the types of conferences available in the Enterprise Collaboration Preferred Architecture and explains how to deploy conferencing capability.
• Collaboration Edge — Explains how to deploy Cisco Collaboration Edge components to provide remote registration services, external communications, and interoperability.
• Core Applications — Lists the various applications and deployment tools available in the Enterprise Collaboration Preferred Architecture, and focuses on two core applications for unified messaging and conference scheduling.
• Sizing — Provides simplified sizing examples to size the components of the Enterprise Collaboration Preferred Architecture to fit the requirements of your deployment.
