IP Telephony

IP telephony transmits voice communications over the network using open, standards-based Internet Protocol. As such, it provides a way for you to extend consistent voice communications services to all your employees in their workspaces – on the main campus, at branch offices, remote, or mobile. Cisco IP telephony solutions are an integral part of Cisco Unified Communications, which unify voice, video, data, and mobile applications on fixed and mobile networks. They let your employees talk with each other using almost any media, device, or operating system. Using its network as the platform, almost any size organization can gain the inherent benefits of using a converged network for transport and interconnection. That enables you to provide highly secure and reliable communications that take advantage of your LAN and WAN, improve employee flexibility and productivity, and take advantage of a wide range of Session Initiation Protocol (SIP)-based capabilities. Cisco Unified Communications call processing systems deliver voice, video, mobility, and presence services to IP phones, media processing devices, VoIP gateways, mobile devices, and multimedia applications. Cisco IP phones are available in wired and wireless versions and provide handset functionality for Cisco Unified Communications Manager, SBCS, and XML applications. Softphones such as Cisco IP Communicator and Cisco Unified Personal Communicator extend voice and multimedia functionality to Windows and Mac computers.
