Typical VoIP communication
Voice over IP (VoIP) allows analog signals to be converted to digital signals, then transmitted on a network. By using existing technologies and software, voice communication over the Internet is now available to anyone with a browser (think Skype, WebEx, Google Hangouts). Beyond this, many companies are now offering VoIP-based telephone service for business and home use.
