VoIP technology
Voice over Internet Protocol (VoIP) is a form of telecommunication where conversation travels through the Internet (or other IP-based data network) instead of the traditional telephoning system. For its many practical reasons, VoIP is a trending technology nowadays, which spreads in wider and wider circles all around the world. Although, VoIP itself is relatively new (invented in 1994), it will soon bring a revolution in our everyday telecommunication. It already is in common use in the business sphere.
