Book excerpt: "Voice communications networks and IP data networks have almost nothing in common beyond being networks: IP networks are packet switched, while voice networks are circuit oriented. Doing voice over IP can pose real problems, as the documents included in this volume attest. Reconciling those differences is key to the ultimate success of IP telephony. Integration of voice into existing applications, such as web or email, is covered here as is the architecture for performing telephony functions and the infrastructure for providing a transport for real-time applications such as voice communications.".
