  • 1. VoIP
  • 2. How VoIP / Internet Voice Works VoIP services convert your voice into a digital signal that travels over the Internet 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.
  • 3. What Are Some Advantages of VoIP? Some VoIP services offer features and services that are not available with a traditional phone, or are available but only for an additional fee. You may also be able to avoid paying for both a broadband connection and a traditional telephone line.
  • 4. What Are Some disadvantages of VoIP? If youre considering replacing your traditional telephone service with VoIP, there are some possible differences: Some VoIP services dont work during power outages and the service provider may not offer backup power. Not all VoIP services connect directly to emergency services through 9-1-1. For additional information, see VoIP & 911 Advisory. VoIP providers may or may not offer directory assistance/white page listings.
  • 5. History 1964 Paul Baran, "On distributed Communications Networks," IEEE Transactions on Systems (March 1964) (described as "first paper on secure packetized voice) 1972 Dr. Vint Cerf was the man who invented Transmission Control Protocol / Internet Protocol (TCP/IP) – the technical protocol that defines the form of net data packets and how they travel to their destinations. 1995 by a small company in Israel called Vocaltec, Inc. Their product, InternetPhone, allowed one user to call another user via their computers, a microphone and a set of speakers. Additionally, this application/product only worked if both the caller and the receiver had the same software setup.
  • 6. Examples
  • 7. VoIP Future VoLTE Voice over LTE is the future. VoLTE shares many of the same benefits that VoIP does, but instead of relying on the hardware at the ends of the call (your smartphone), VoLTE offloads the heavy lifting to the network. Doing so lets VoLTE calls be described as VoIP HD. Calls are crisp and clear, and reportedly sound amazing. Not only that, VoLTE includes the ability to cancel echos and background noise on the back end, not the handset itself.
