Origins

Take the speed and the possibility of interactive discussions before Internet private LANs (computer).

The h. 323 protocol by the International Telecommunication Union 1996 created for transmission over local area networks primarily video conferencing published standards. With the creation of broadband, these standards have been adapted for use in the Internet. The standard is called "packet - based multimedia communications systems" and the transmission of audio or video data on networks.

The Internet Engineering Task Force (IETF)

The IETF defined later other protocols VoIP, specifically the Protocol SIP (session initiation) and the real-time Transport Protocol (RTP) real.

These two systems are most common for the end user as h. 323, used, used for the transmission of bulk voice data applications.

VoIP software

Commercially available software is more likely than h. 323 protocols on SIP and RTP based.

Commercial service providers offer usually a router that is pre-installed with their proprietary software. Thus, the consumer buys a combination of hardware and software. However, it is possible to install VoIP software on a computer with Internet-ready. Two examples are MSN Messenger and Yahoo Messenger. Skype offers a downloadable program and R solution Exchange material that contains a handset. Users who deciden need to install software to have a microphone and a loudspeaker connected or integrated into your computer.
