IP Telephony

If you've never heard of Internet Telephony, get ready to change the way you think about long-distance phone calls. Internet Telephony, or Voice over Internet Protocol, is a method for taking analog audio signals, like the kind you hear when you talk on the phone, and turning them into digital data that can be transmitted over the Internet.
How is this useful? Internet Telephony can turn a standard Internet connection into a way to place free phone calls. The practical upshot of this ....etc

The limitations of the circuit-switching techniques of conventional telephony may now be overcome through integration with IP technologies. Internet Telephony is a powerful and economical communication option by combination of the telephone networks and data networks. IP telephony used to send audio, video, fax etc between two or more users in real time via packet switched network. The main motivation of IP telephony is Cost savings and ease of developing and integrating new services. Four type of IP telephon ....etc

Packet Telephony

Packet Telephony consists of telephony and data tightly coupled on packet based switched multimedia networks. The packet telephony simply refers to the use of personal computers and a packet data network to produce a voice conversation. The goal of packet switched fabric in both LAN and WAN, the vision in to drive voice and data over a single multimedia (packet based N/W) allowing waves to engage in a media rich communication in a natural and straight-forwarded manner. The packet & based fabric is capable of supporting futur ....etc

Communication via packet and data networks such as IP, ATM, Frame Relay has become a preferred strategy for both corporate and public networks. Experts predict that data traffic will soon exceed telephone traffic if it already hasnâ„¢t. As a result of this there has been considerable interest in transmitting traditional telephone traffic over data
networks. Internet Telephony is a powerful and economical communication options. It is a general term for the technologies that use the Internet Protocol's pac ....etc
