V o IP

1. VoIP Michael Laport Robin Heath “I truly believe that VoIP is the telecommunications wave of the future,” said Travis Mack, a VoIP customer of only a year.

2. Abstract Idea. • Voice over Internet Protocol • Internet calling • Making phone calls over broadband networks rather than traditional landlines or wireless networks. • Transition from analog messages to digital data moving across Internet framework. • Actually been in use for several years in long distance calling.

3. Standard Calling. • Existing phone systems are driven by a very reliable but somewhat inefficient method for connecting calls called circuit switching. (1) • Circuit switching is a very basic concept that has been used by telephone networks for more than 100 years. When a call is made between two parties, the connection is maintained for the duration of the call. (1)

4. Standard Calling. • During a 10 minute phone call the circuit is open for 10 minutes. • In the early phone system, up until 1960 or so, every call had to have a dedicated wire stretching from one end of the call to the other for the duration of the call. (1) • Today's traditional phone network are somewhat more efficient. Your voice is digitized, and your voice along with thousands of others can be combined onto a single fiber optic cable for much of the journey. (1)

5. VoIP Calling. • Data networks do not use circuit switching. Instead, data networks simply send and retrieve data as you need it. • And, instead of routing the data over a dedicated line, the data packets flow through a chaotic network along thousands of possible paths. This is called packet switching. (2)

6. Data-level VoIP. • A codec converts the audio signal into a compressed transmission, then back into the audio signal at either end. • Different protocols are used to connect different devices (such as IP phones, computers, or ATA’s) as to secure the collaboration of different networks.

7. Three Ways to VoIP. • ATA (Analog Telephone Adaptor) • Converts a standard phone signal to digital so that VOIP will work. • IP Phone • Specialized phones that comes ready for VOIP service. Instead of having the standard RJ-11 phone connectors, IP phones have an RJ-45 Ethernet connector. (3) • Computer to Computer • Easiest way to use VOIP. All you need is the software.

8. What is all the buzz about? VoIP. • VOIP can offer all the services of normal phone services (voice mail, call waiting, etc.). • Plus More: • Email notification for voice mail • Keep current phone number, or choose any number available by your service provider • Computer interface or normal phone, either work • Portable service (VoIP adapter can travel with you) • Merges service providers, lowers cost to you • Replaces traditional land line and long distance.

9. What makes VoIP so tantalizing? • One network for communications • No more long distance fees • Perhaps the biggest advantages is the use of digital data opens avenues in the communications and entertainment markets.

10. The Hurdles for VoIP. • Transition from a 100+ year old copper phone network to a budding broadband network causes some inadequacies. • Reliability • Dependant on wall power • Emergency 911 calls • Network latency, packet loss, • Computer systems resource drains • Loss of packets • Number of phone jacks limited per service • Need broadband • Security

11. Skype. • Basic Program can be downloaded for free. • Acts as a fancy chat program like AOL-IM. • Allows for chat, text, and voice between people who have Skype. • Pay Services: • SkypeOut – Allows you to call non-Skype users including traditional phones and cell phones. • SkypeIn – Gives you a regular phone number so that people with traditional phones and cell phones can call. • Skype Voicemail – Gives Skype users a virtual answering machine similar to what most cell phones have. • Skype is not a replacement for your ordinary telephone and can’t be used for emergency calling. (4) It does not support regular 911 service.

12. Local Service VoIP. • Relatively Local Providers • Vonage • Comcast • Local Providers NOT needed. • 513 US Providers (5) • Local Providers give a local physical phone number. • Any provider can be used as you connect over the internet.

13. VoIP applications. • The integration of different mediums into one communication device. More seamless than other methods.

14. Business VoIP. • Virtual numbers for business • Save customers long distance fees. • Internal Operations; Sales force –to- developers, no long distance. • Teleconferencing is an ease • Cellular phone calling enabled by WiFi and WiMax

15. Business VoIP (Some Vonage offers). • Outlook plug-in to call directly from a contact list • Browser plug-in to call a number by selecting a number on any web page • Business web page where customers can enter their phone number to initiate a call from your customer service department to them
