Unified Presence Server 1.0 Server Software
The Cisco® Unified Presence Server is a critical component for delivering the full value of a Cisco Unified Communications environment. It collects information about a user's availability status, such as whether or not you are using a communications device such as a phone at a particular time. It also collects information regarding a user's communications capabilities, such as whether Web collaboration or video conferencing is enabled. Using user information captured by the Cisco Unified Presence Server, applications such as Cisco Unified Personal Communicator and Cisco Unified CallManager can improve productivity by helping users connect with colleagues more efficiently through determining the most effective way for collaborative communication.
The Cisco Unified Communications system of voice and IP communications products and applications enables organizations to communicate more effectively-helping them to streamline business processes, reach the right resource the first time, and impact the top and bottom line. The Cisco Unified Communications portfolio is a key part of the Cisco Business Communications Solution-an integrated solution for organizations of all sizes which also includes network infrastructure, security, and network management products, wireless connectivity, and a lifecycle services approach, along with flexible deployment and outsourced management options, end-user and partner financing packages, and third-party communications applications.
Cisco Unified Presence Server enables you to deploy Session Initiation Protocol (SIP) technology to support new voice services in your 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 Server uses SIMPLE (SIP for Instant Messaging and Presence Leveraging Extensions) technology to support both instant messaging (IM) and presence.
Cisco Unified Presence Server 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 ability to support voice, video, IM, 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 ensure that only authorized applications and users have access to presence information. The SIP proxy function allows for efficient and accurate routing of both presence and general SIP messaging through the enterprise.
Cisco Unified Presence Server is strongly integrated with various desktop clients and applications. It enables Cisco Unified Personal Communicator, the Cisco enterprise desktop client, to perform numerous functions such as click-to-dial and phone control as well as voice, video, and Web collaboration. In addition, Cisco Unified Presence Server provides a core IM service for Cisco Unified IP Phones connected to Cisco Unified CallManager. Cisco Unified Presence Server also supports interoperability with enterprise desktop applications such as IBM Sametime and Microsoft Office Communicator, enabling these desktop applications to operate in conjunction with Cisco Unified IP phones supported on Cisco Unified CallManager.
