  1. Overview • Present the past, present & future of VoIP. • Focus: • Technology • Cultural Factors • Economic Factors • Regulatory Factors

  2. Technology Overview • What is VoIP • The “Real Time” transmission of voice signals using the Internet Protocol (IP) over the public Internet or private data network. • Process of Data Transfer • Voice signal is “packetized” • Voice becomes data: dismantled > compressed > transferred > decompressed > assembled

  3. The Past • Three fundamental technologies that need to exist: • Telephone • Internet/Intranet (public or private) • Transmission Control Protocol / Internet Protocol(TCP/IP) • The history of the Telephone • The history of the Internet • TCP/IP • Invented by Dr. Vint Cerf in 1972 • Defines the form of net data packets and how they travel to their destinations

  4. The Past (continued) • VoIP started in 1995 by VocalTech, Inc. in Israel • Worked from computer to computer • In 1998 the first PC to phone calls took place • Supervening Necessity • No regular telephone service • Developed to circumvent legacy networks’ monopoly • Just want to avoid a long distance bill.

  5. The Present • The Present: • Business adoption and cultural impact • Economic & Financial impact • Regulation • Business and adoption of VoIP • Lower the cost of communicating • Converge telephone infrastructure with existing data network • Cultural Impact? • Call center jobs moving away from the U.S. • 250,000 jobs moved since 2001 • Need to support products • Operating Hours • Outsourced staff is highly educated

  6. The Present (continued) • Economics and Finances • Four groups are affected by VoIP • U.S. Federal Government • FCC has taken the regulatory right from the individual states • The technological nature of VoIP - distributed network • This affects local tax revenue • AT&T sends “part” of their calls over the Internet

  7. The Present (continued) • Legacy Networks • Verizon has lost 9 million phone lines in the northeast (16% of total) • AT&T’s revenue is down 18% since 2001 • Bells have lost 28 million phone lines since 2001 • Resemble the railroads • WW2 - move from train to automobile and airplane

  8. The Present (continued) • Cable companies (the ultimate ITSP) • Pressure from Satellite - need to expand to stay competitive • Already have a wired connection to the home • Can offer bundled services • Cable television • Hi-speed Internet Service • Telephone Service • Businesses who adopt the technology (#4) • Benefits are there for large companies / not for small COs. • Most say that the real benefit is the enhanced data network.

  9. The Present (continued) • More on the regulatory role of the U.S. federal government • Take the regulation away from the states • ITSPs must pay 911 emergency assistance tax • ITSP are worried that they will be regulated like legacy networks • The CALEA (Communications Assistance for Law Enforcement Act) (1994) • Electronic surveillance for “telecommunication” service providers • Does this Act (and the 1996 telecommunications Act) open the door for the U.S. government to regulate the Internet?

  10. The Future • Increased number of users • 2003 - 131,000 users (in the U.S.) • 2004 - 1,000,000 users (in the U.S.) • Expand to other platforms • Mobile market and PDAs • Transform the traditional cell phone • Use of WiFi networks • One number - Persistent Personal Profile • It may be possible to connect with one universal number (email, phone, fax, etc.) • No longer dependent on a fixed geographic location • Converging Media • Data, Voice, Images, Video
