Difference Between VoIP and IP Telephony IP telephony (Internet Protocol telephony) is a general term for the technologies that use the Internet Protocol's packet-switched connections to exchange voice fax and other forms of information that have traditionally been carried over the dedicated circuit-switched connections of the public switched telephone network (PSTN). Using the Internet calls travel as packets of data on shared lines avoiding the tolls of the PSTN. The challenge in IP telephony is to deliver the voice fax or video packets in a dependable flow to the user. Much of IP telephony focuses on that challenge. VoIP (voice over IP - that is voice delivered using the Internet Protocol) is a term used in IP telephony for a set of facilities for managing the delivery of voice information using the Internet Protocol (IP). In general this means sending voice information in digital form in discrete packets rather than in the traditional circuit-committed protocols of the public switched telephone network (PSTN). A major advantage of VoIP and Internet telephony is that it avoids the tolls charged by ordinary telephone service. VoIP specifically refers to sending voice traffic over an IP (Internet Protocol) network. Voice and data convergence refers to sending both voice and data (such as LAN traffic) over any data network (typically an IP network frame relay network or ATM network). IP telephony refers to any telephone type service carried over IP - this could include faxing. VoIP is voice over IP only. Sometimes telephony also includes text messaging. more details
