This week's sneak peek of a Cisco Press book is Voice over IP Fundamentals, 2nd Edition by Jonathan Davidson, James Peters, Manoj Bhatia, Satish Kalidindi, and Sudipto Mukherjee. The book explains how a basic IP telephony infrastructure is built and works today, major concepts concerning voice and data networking, and transmission of voice over data networks. You’ll learn how voice is signaled through legacy telephone networks, how IP signaling protocols are used to interoperate with current telephony systems, and how to ensure good voice quality using quality of service.
