  • The following is a presentation of Voice over Internet Protocol – written and produced by Tyson Courtney and Chantelle Charlebois
  • Topics to be covered include What VoIP is and how it works. Who Uses it? The use of VoIP in Canadian homes. The advantages and disadvantages of VoIP usage. The Future of VoIP service in the world market.
  • Voice over Internet Protocol – or VoIP – What is it? is the process of converting analog audio signals into digital data that is transmitted via the internet. Information is transmitted by one of two methods, which is dependant on the method and/or service provider packet-switching or circuit switching. The original concept evolved in 1995 by Vocaltec with the release of the first internet phone. Robert Valdes and Dave Roos, “ How VoIP Works” . Retrieved October 22, 2010 from http://communication.howstuffworks.com/ip-telephony.htm   Author Unknown, “The History of VoIP” . Retrieved October 22, 2010 from http:// www.whichvoip.com/voip/articles/voip_history.htm  
  • There are three ways in which to utilize VoIP services: analog telephone adapters (ATA) IP phones and computer-to-computer Robert Valdes and Dave Roos, “ How VoIP Works” . Retrieved October 22, 2010 from http://communication.howstuffworks.com/ip-telephony.htm  
  • ATA is the most common method and requires that your telephone be connected to your computer and the internet. The signal from a traditional phone is converted into digital information and sent over the internet. The telephone cable is simply attached to the ATA instead of directly into the wall. The ATA converts the analogue data from your phone into digital information before it leaves the home.
  • IP phones have RJ-45 Ethernet connectors connected directly to a modem instead of the traditional RJ-11 connector plugged into the wall. The phones looks and works like a traditional phone but is plugged in to your modem instead of the wall.
  • Computer-to-computer is the simplest way to use VoIP and can often be accessed for free or with the purchase of low-cost software. With simple computer software, hardware - microphone, speakers, soundcard - and an internet connection - DSL or cable is preferred – calls can be made from one computer to another. Skype is currently the most popular computer-to-computer VoIP provider.
  • Digital information can be transferred in one of two ways depending on the infrastructure used to transmit the digital data. The first method is circuit switching, and is the traditional method – the connection between the two connecting parties remains open in both directions for the duration of the communication.
  • The second method is packet-switching and it works in a single direction only – while one part talks the other listens which means only half the connection is required at any given time. Packet-switching requires about half the connectivity of circuit-switching, is efficient and decreases online traffic.
  • In 2006 Statistics Canada reported that less than one-quarter of household used only a traditional land-line telephone and that there has been a dramatic shift to cell phones and VoIP services. From December 2006 to December 2007 household use of VoIP service increased from 10.7% to 14.9%.  
  • Of households without land-line service 31.7% report using VoIP. VoIP usage in rural areas accounts for 3.5% of ‘telephone’ communication versus 14.1% in rural areas. This variation can be largely attributed to the lack of modern infrastructure to support VoIP use. Statistics Canada, “Residential Telephone Service Survey” . Retrieved October 24, 2010 from http://www.statcan.gc.ca/daily-quotidien/080423/dq080423d-eng.htm
  • Business usage is steadily increasing as service providers are moving to more unified communications – providing phone, cell phone fax, voicemail, email and web access within the same infrastructure with less cost. Efficiency of bandwidth and the low cost of VoIP technology is a driving force for the switch from traditional systems to VoIP systems. Renee Hopkins Callahan, “ Businesses Move To Voice-Over-IP ”. Retrieved October 26, 2010 from http://www.forbes.com/2008/12/09/skype-vonage-ringcentral_leadership_clayton_in_rc_1209claytonchristensen_inl.html  
  • In September 2009 Skype Ltd. Began providing Canadian iPhone users the ability to use VoIP wirelessly buy downloading a free application. This allows users to ‘Skype’ with other Skype users free of charge. Calls can also be placed to landline or cell phone users for the regular rate for Skype users. With over 6 million downloads and compatibility with the iPhone, iPod Touch and iPad, wireless VoIP stands to make for interesting competition for cell phone providers.
  • So, your asking yourself “What are the advantages of VoIP?” First of all… Savings, Savings, SAVINGS! In all cases you are going to save money on your bill whether you are a homeowner or a business the savings are significant. Usually your calls to Canada and the US are included in your quote service price, and your long distance fee will drop as well. How about, all the standard call features are available such as - Voicemail, Caller ID, Call waiting, Call forwarding, Three-way calling, Do not disturb, Call return, Anonymous call blocking, Online billing, Find Me, Follow Me service, Local number porting, and to Choose your own area code - many of which are offered for free. Also, many VoIP phone adapters can be taken to any Internet connection allows for great flexibility with its usage. Service, can be integrated with your Computer via Applications to bring together email, faxing, video/voice messaging. It also, requires less bandwidth on your service lines, which frees up space for your other service to run faster and freer. ("Home voip basics ," 2008)
  • With the good also comes the, not so good... If your internet is down, so is your VoIP service There is no service during a power outage While traditional phones can trace your location in times of emergency, where with VoIP there is currently no way to tracing – the solution…
  • A program called E911 is in place in some countries which require a VoIP customer to contact their Public Safety Access Point (PSAP).
  • In our opinion, we would recommend this service for those with a reliable Broadband Connection, those with the need to use more than just voice calling such as video messaging (Skype) and of course, those who want to save money. To us, the benefits outweigh the disadvantages.
  • In the coming future we can see VoIP phones taking over the market. A current study by Pin Point Topics, an analysts firm has reported that 1 out of every 5 broadband users has VoIP services and that at the end of 2009 there were over 100 million users. As broad band connection advances and expands into new regions; more and more customer will be able to enjoy the benefits. Pin point then goes onto project that by 2015 there will be more than 200 million users. These figures don’t incorporate companies such as Skype which can go anywhere with 3 and 4G networks for cell phones and wireless-to-go cards.   The future is definitely bright for the VoIP services.
  • Thank you for taking the time to view our presentation on VoIP. We hope that we were able to enlighten you and to dispel some of the fallacies associated with VoIP service.
