VOIP Internet Telephony About VOIP Processes VOIP Phone System Challenges in VOIP  Residential VOIP

Voice over Internet Protocol (VoIP, IPA) is a general term for a family of transmission technologies for delivery of voice
communications over the Internet or other packet-switched networks. Other terms frequently encountered and
synonymous with VoIP are IP telephony and Internet telephony, as well as voice over broadband, broadband telephony,
and broadband phone, when the network connectivity is available over broadband Internet access.

VoIP systems usually interface with the traditional public switched telephone network (PSTN) to allow for transparent
phone communications worldwide[1].

VoIP can be a benefit for reducing communication and infrastructure costs by routing phone calls over existing data
networks and avoiding duplicate network systems. Skype and Vonage are notable service provider examples that have
achieved widespread user and customer acceptance and market penetration. Other providers are also available. See List
of commercial voice over IP network providers.

Voice-over-IP systems carry telephony speech as digital audio, typically reduced in data rate using speech data
compression techniques, packetized in small units of typically tens of milliseconds of speech, and encapsulated in a
packet stream over IP.

Can I call using the internet connection?
After its introduction, Internet telephony has been highly developed rapidly in a brief period. Many software developers
currently offer PC telephony software. However, more importantly, gateway servers are rising to act as an interface
between the Internet and the PSTN (It expands as Public Switched Telephone Network). With voice-processing cards,
these gateway servers allow Internet telephony VoIP(It expands as Voice Over Internet protocol) users to communicate
through traditional telephones over long distances without exceeding "Long Distance" telephone network.

A telephone call travels from the local PSTN to the nearest gateway server, which digitizes the traditional, analog voice
signal, converts it into IP packets, and moves it to the Internet for transport to a gateway server at the receiving end.
This server alters the digital IP signal back to analog and concludes the call locally. With its Internet telephony support
for computer-to-telephone calls, telephone-to-computer calls and telephone-to-telephone calls, Internet telephony VoIP
represents a vital step toward the merging of voice and data networks.
The History and Advances made in Internet Technology
Voice ove r Internet Protocol (VoIP) is becoming a substitute to traditional telephone service. The goal of VoIP
Deployment is to receive the registered location information of a VoIP user to the most suitable public safety answering
point (PSAP) through statewide standards using the 9-1-1 network.
