Cisco Unified Presence - License Product Details
Cisco Unified Presence is a crucial component for delivering the full value of a Cisco Unified Communications environment. It collects information about a user's availability status, such as whether the user is using a communications device such as a phone at a particular time. It also collects information regarding a user's communications capabilities, such whether Web collaboration or video conferencing is active. Using information captured by Cisco Unified Presence, applications such as Cisco Unified Personal Communicator and Cisco Unified Communications Manager (formerly Cisco Unified CallManager) can improve productivity by helping users connect with colleagues more efficiently by determining the most effective means for collaborative communication.Cisco Unified Presence takes advantage of Session Initiation Protocol (SIP) technology to support new voice services in the enterprise environment. SIP enhances the voice network by providing a core set of behaviors for session establishment and control that can be applied in a wide array of features and services. In addition to core SIP support, Cisco Unified Presence uses SIP for Instant Messaging and Presence Leveraging Extensions (SIMPLE) technology to support both instant messaging and presence.Cisco Unified Presence consists of a SIP presence engine and a SIP proxy function. The presence engine collects user presence information (such as busy, idle, away, or available status) as well as user capabilities (such as the capability to support voice, video, instant messaging, and Web collaboration) and compiles the data in a repository for each user. This repository is accessed by the applications and features that each user employs. Unique user rules and privacy can be applied by each user to help ensure that only authorized applications and users have access to presence information. The SIP proxy function facilitates efficient and accurate routing of both presence and general SIP messaging through the enterprise.
