The second-generation Cisco IP phones bring state-of-the-art technology to voice communication solutions. Cisco Systems, the worldwide leader in networking for the Internet, now delivers new opportunities for rapid deployment of classic and New World voice applications by providing high-quality voice instruments that use IP transport technology. This allows for the consolidation of data and voice into a single network infrastructure, including a single cable plant, a single switched Ethernet fabric for campus or branch offices, and unified systems for operations, administration, and management (OAM) for data and voice.The Cisco IP Phone is a standards-based communications appliance. Cisco IP series phones can interoperate with IP telephony systems based on Cisco CallManager1 technology, H.323, Session Initiated Protocol (SIP) and, in the future, Media Gateway Control Protocol (MGCP), with system- initiated software updates. This multi-protocol capability is an industry first and provides investment protection and migration capability.The Cisco IP Phone 7940 is a second-generation, full-featured IP phone for low to medium traffic users who require a minimum of directory numbers. It provides two programmable line/feature buttons capable of four simultaneous calls and four interactive soft keys that guide a user through call features and functions. The Cisco IP Phone 7940 also has a large, pixel-based LCD display. The display provides features such as date and time, calling party name, calling party number, and digits dialed. The graphic capability of the display allows for the inclusion of present and future features.
