This paper provides an outline to our Learning Team C's Project, Understanding the Advantage and Disadvantages of Voice over Internet Protocol (VoIP). This outline will cover the following areas: Provide a detail description of what is VoIP; Identify what technology is involved with VoIP; Provide future trends in VoIP; Provide example of companies involvement with VoIP; Identify regulatory issues surrounding VoIP; and identify any global implications of VoIP.


1. What Is Voice Over Internet Protocol (VoIP)
a. VoIP, or Voice over Internet Protocol, is a method for taking analog audio signals, like the kind you hear when you talk on the phone, and turning them into digital data that can be transmitted over the Internet.   VoIP is a revolutionary technology that has the potential to completely rework the world's phone systems.

2. Technology Involved With VoIP
a. Once people realized that they could use a computer to send traditional telephone traffic over the Internet, there was no looking back.   Voice over Internet Protocol (VoIP) got its start around 1995 when hobbyists started testing the concept (http://www.voipreview.org/news.details.aspx?nid=51).   The VoIP industry didn't really start until 1998 when the first companies started offering PC to phone service thereby allowing a PC user to call a traditional landline telephone.   AS time passed and larger companies like Cisco and Lucent started getting involved in the industry, in 2000 VoIP services accounted for 3% of the voice traffic (http://www.whichvoip.com/voip/articles/voip_history.htm).   As these larger players came on board there was much discussion and development of competing technologies.
b. There are many varieties of VoIP.   A VoIP calls consists of 2 parts.   One part is the signaling that will control the call flow like sending a busy message or hanging up the call.   Another part is the media, also known as RTP (Real Time Protocol), which is the actual voice part of the call.   Each...
