This information site describes the Cisco Unified Communications system for IP telephony. Cisco Unified Communication solutions integrates voice, data, and video communications together into a single network, thereby making it simple, scalable, and cost-effective solutions.
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 link at the bottom of every TOC. To learn more about how to navigate through this site, see Using This Information System.
