Voice over IP

Voice over Internet Protocol VoIP , also called IP telephony , is a method and group of technologies for the delivery of voice communications and multimedia sessions over Internet Protocol IP networks, such as the Internet. The terms Internet telephony , broadband telephony , and broadband phone service specifically refer to the provisioning of communications services voice, fax , SMS , voice-messaging over the Internet, rather than via the public switched telephone network PSTN , also known as plain old telephone service POTS. The steps and principles involved in originating VoIP telephone calls are similar to traditional digital telephony and involve signaling, channel setup, digitization of the analog voice signals, and encoding. Instead of being transmitted over a circuit-switched network , the digital information is packetized and transmission occurs as IP packets over a packet-switched network. They transport media streams using special media delivery protocols that encode audio and video with audio codecs and video codecs. Various codecs exist that optimize the media stream based on application requirements and network bandwidth; some implementations rely on narrowband and compressed speech , while others support high-fidelity stereo codecs.

Jump to navigation. Voice over Internet Protocol VoIP , is a technology that allows you to make voice calls using a broadband Internet connection instead of a regular or analog phone line. Some VoIP services may only allow you to call other people using the same service, but others may allow you to call anyone who has a telephone number - including local, long distance, mobile, and international numbers. VoIP services convert your voice into a digital signal that travels over the Internet. If you are calling a regular phone number, the signal is converted to a regular telephone signal before it reaches the destination. VoIP can allow you to make a call directly from a computer, a special VoIP phone, or a traditional phone connected to a special adapter.
