Cisco® Unified Communications Solutions unify voice, video, data, and mobile applications on fixed and mobile networks, delivering a media-rich collaboration experience across business, government agency, and institutional workspaces. These applications use the network as the platform to enhance comparative advantage by accelerating decision time and reducing transaction time. The security, resilience, and scalability of the network help users in any workspace to easily connect every time, everywhere, using any media, device, or operating system. Cisco Unified Communications is part of a comprehensive solution that includes network infrastructure, security, wireless, management applications, lifecycle services, flexible deployment and outsourced management options, and third-party applications.

Cisco IP Communicator (Figure 1) is a Microsoft Windows-based application that delivers enhanced telephony support through personal computers. It is easy to deploy and features some of the latest technology and advancements available with IP communications today. This application endows computers with the functions of IP phones, providing high-quality voice calls on the road, in the office, or from wherever you can access the corporate network. Cisco IP Communicator supports Session Initiation Protocol (SIP) as well as the Cisco Unified Communications Manager Skinny Client Control Protocol (SCCP).

Figure 1. Cisco IP Communicator
Cisco IP Communicator is designed for users who require a supplemental telephone when away from their desk or traveling or telecommuting. When using Cisco IP Communicator remotely, you are not just taking your office phone extension with you - you still have access to the same familiar phone and video telephony services you have in the office. This advantage boosts business collaboration and responsiveness, and helps organizations keep pace with today's mobile business environment.
Cisco IP Communicator works with Cisco Unified Video Advantage to bring video telephony to the communications experience. Now, telecommuters and mobile employees using Cisco IP Communicator can enhance their communications with video. When calls are made through Cisco IP Communicator, available video is automatically displayed through Cisco Unified Video Advantage. It is as easy as making a telephone call.
Cisco IP Communicator uses the Cisco Unified Communications Manager call-processing system to provide advanced telephony features and voice-over-IP (VoIP) capabilities. Access to eight telephone lines (or a combination of lines and direct access to telephony features) is included. When registered to the Cisco Unified Communications Manager system, Cisco IP Communicator has the capabilities of a full-featured Cisco Unified IP phone, including the ability to transfer calls, forward calls, and add participants to an existing conference call. As a result, system administrators can provision Cisco IP Communicator as they would any other Cisco Unified IP phone, greatly simplifying IP phone management. This solution also can help customers and developers deliver more innovative and productivity-enhancing Extensible Markup Language (XML)-based applications to the display.
