The primary types of IP telephony system components are grouped in the following categories:
•Call control—Cisco Unified Communications Manager is the core call processing software for the Cisco IP telephony system. It builds call processing capabilities on top of the Cisco IP network infrastructure. It extends enterprise telephony features and capabilities to packet telephony network devices such as Unified IP phones, media processing devices, Voice over IP (VoIP) gateways, and multimedia applications.
•Applications—Cisco Unified Application Environment is the core software component that enables the development of customized applications that streamline business processes and drive productivity through IP-based Unified Communications.
•Conferencing—Cisco Unified MeetingPlace is the core conferencing software that provides integrated voice, video, and Web conferencing capabilities to enable remote meetings that are natural and effective with face-to-face quality, such as meetings, training sessions, and presentations.
•Voice mail and messaging—Cisco Unity is the core messaging software that delivers powerful voice, integrated, and unified messaging options that transparently integrate with Microsoft Exchange, Lotus Domino, and Novell GroupWise.
•Endpoints and clients—Cisco IP Communicator is the core software that integrates the management capabilities of IP-based networks with phones, pagers, and computers and use these for signaling, voice communications, and data communications.
•Wireless and Mobility—Cisco Unified Mobility Advantage, Cisco Unified Mobile Communicator, and Aironet Wireless Access Points are the core software and hardware components that enable secure and scalable methods to real-time access to instant messaging, e-mail, and network resources.
•Security—Cisco Advanced Services Appliance ASA 5500 Series, Firewall Services Modules, and Cisco Intrusion Prevention System Appliance IPS-4200 are the core hardware and software components that process new threats to the network by using proactive, automated, real-time threat management.
•Network management—Cisco Unified Operations Manager is the core software component that provides an integrated view of the entire Cisco Unified Communications system and presents the current operational status of each component of the IP communications network.
•Infrastructure—Cisco routers, voice gateways, and Cisco Unified Telepresence Multipoint Switches are the core hardware components that provide reliable connectivity that is more resilient and enables all the latest network services.
