Multiservice Infrastructure

The infrastructure component includes public switched telephone network (PSTN) gateways, analog phone support, and digital signal processor (DSP) farms. The infrastructure can support multiple client types such as hardware phones, software phones, and video devices. Infrastructure also includes the interfaces and features necessary to integrate legacy PBX, voice mail, and directory systems. Typical products used to build an infrastructure include Cisco voice gateways (non-routing, routing, and integrated), LAN switches, LAN/WAN routers and voice application systems.

IP Phones

Cisco IP Phones are a full range of intelligent communication devices designed to take advantage of the power of your data network, while providing the convenience and ease-of-use you’ve come to expect from your business phone. In the IP environment, each phone has an Ethernet connection. IP phones provide the functionality you expect to receive from a traditional telephone, as well as more complicated features, such as the ability to access World Wide Web sites. Typical user instruments include Cisco IP Phones and Cisco IP SoftPhones.

Cisco CallManager

At the heart of the IP telephony system is Cisco CallManager, the software-based call processing agent. Cisco CallManager software extends enterprise telephony features and capabilities to packet telephony network devices such as IP phones, media processing devices, voice-over-IP (VoIP) gateways, and multimedia applications. Additional data, voice, and video services such as unified messaging, multimedia conferencing, collaborative contact centers, and interactive multimedia response systems interact with the IP telephony solution through Cisco CallManager’s open telephony application programming interfaces (APIs).

Voice Software

Voice applications are physically independent from the call processing and voice processing infrastructure and they may reside anywhere within your network. Leveraging a single network infrastructure provides an open platform for powerful productivity applications, and serves as a solid foundation for future convergence-based applications that will continue to advance enterprise communications.
