Excerpted from the “Integrating the Cisco Unified Presence Server in Your Unified Communications Network” white paper. You can download the entire paper from our Knowledge Center.

1. Cisco Unified Presence Server (CUPS) – This is the brain of the Presence architecture and works in almost the same manner that the Cisco Unified Communications Manager (CUCM) does. For example, CUPS servers are organized into clusters of up to six servers for redundancy. Also, the first CUPS server is designated as the Publisher and the other servers are designated as Subscribers.

2. Cisco Unified Communications Manager (CUCM) – This is the main call-processing component of any Voice over IP (VoIP) infrastructure and will be the primary device the CUPS cluster will integrate with. It controls the endpoint devices that will report the presence status to the CUPS server and, if watching devices are located across different dialing areas, it will be responsible for properly routing the call between endpoints.

3. Cisco Unified Personal Communicator (CUPC) – This desktop application gives employees access to all their UC services. It registers to the CUPS and CUCM servers, and unifies the functionality of the following two clients.

4. Cisco Unified MeetingPlace/MeetingPlace Express – These servers integrate voice, video, and web conferencing capabilities, and let you incorporate media interactions in a broad range of communication
scenarios. Cisco Unified MeetingPlace is deployed as an on-premise solution run over internal networks.

5. Cisco Unity/Unity Connection – These servers provide advanced, convergence-based communication services such as unified messaging and voice messaging. Cisco Unity is a Windows-based application capable of supporting unified messaging, while Unity Connection is a RedHat Linux-based appliance solution that supports voicemail only.

6. Cisco Unified Videoconferencing – Designed to scale to both small and large networks, this solution provides a modular and stackable architecture that can support as few as three parties and up to several hundred in a single conference.

7. Lightweight Directory Access Protocol (LDAP) v3.0 – LDAP is an industry-standard protocol designed for accessing and modifying Directories that are optimized for very efficient reading, and provides a means for organizations to centrally locate and organize all of their user information.

8. Cisco Unified IP Phones – Cisco’s 7900-series of IP phones are used as the client endpoint-devices that will report the Presence status for the assigned user.

9. Third-Party Presence Servers – CUPS is able to integrate with other vendor solutions by using Session Initiation Protocol (SIP), as well as a protocol named SIMPLE (SIP for Instant Messaging and Leveraging Extensions).
