This information site describes the Cisco Unified Communications IP telephony system, the Cisco IP solution for integrating data, voice, and video traffic over converged networks. The Cisco Unified Communications IP telephony system sets the world standard for rich-media IP networking.

This site contains system documentation that is presented in the network lifecycle process: Prepare, Plan, Design, Implement, Operate, and Optimize (PPDIOO). PPDIOO is a Cisco methodology that defines the continuous lifecycle of services required by the customer.

Each part of the network lifecycle process has a tab at the top of the page. When you click a tab, the table of contents (TOC) on the left navigation panel changes to show only the TOC for that tab. The opening page on each tab describes what is covered in that phase. You can also use the Index at the bottom of every TOC. To learn more about how to navigate through this site, see Using This Information System.

You can also quickly access additional resources in the Resource Library and Training Library.


This technical information site is designed for people who are implementing Cisco Unified Communications IP telephony systems:

Cisco partners

Cisco system engineers (SEs)

Cisco Technical Assistance Center (TAC) engineers

Cisco customers, especially decision makers, network designers, and operations personnel

The Critical Path to Successful Deployment

The PPDIOO process is the critical path to launch and complete a successful customer deployment, from the request for information (RFI) proposal to successful training of operations personnel. The Cisco Unified Communications system documentation is designed to be used along with the PPDIOO methodology. Each tab on the web interface contains a complete task flow for each phase of the PPDIOO process. Table 1 shows you what type of content you will find on each process tab.

Content Overview

Prepare and Plan

Using evaluative and planning tools, system engineers help partners and customers find the best solution to their business needs. Further planning continues the needs analysis with the goal of producing a high-level project plan and the initial site survey.

Key Content: System description, Release Matrix, market descriptions, planning installations and upgrades


Using the verified customer requirements, the design team creates the detailed design, which includes the equipment list, network diagrams, and traffic flows.

Key Content: Sample deployment models, sample call flows, system test results


Using the site requirements identified in the detailed design, the implementation team performs a detailed site survey to prepare the site for installation. The team orders, inventories, and stages the equipment. The implementation team uses the detailed design to install and configure equipment, then develops and implements a detailed test plan to determine that the network is ready for use.

Key Content: Installation guidelines, test configurations, introduction to troubleshooting methodology


Ongoing operations include managing and monitoring components, performing routine maintenance, managing upgrades, and managing performance and service level agreements (SLA).

Key Content: Call load test results, tested call flows, troubleshooting common problems, recovery procedures


Optimization covers post installation services that are not under a maintenance contract including, but not limited to, performance audits, hardware and software upgrades, and applications development.

Key Content: Upgrade procedures

Resource Library

Key Content: System release documentation, SRNDs, network topology resources, ordering guides, component documentation, configuration command files, system test results, links to related documentation and tools, end-of-sale and end-of-life products, Cisco Unified Communications system demo, Cisco Unified Workspace Licensing, DocWiki.

Training Library

The Training Library provides a single interface to all Cisco Unified Communications instructor-led courses and training videos on demand (VODs).
