Technology is increasing daily and plenty of consumers are facing new
challenges about learning new forms of communication using computer
hardware or software. The changes in our world raise many questions,
and these common questions and answers focus on one growing area of
communication, IP Telephony or Voice over Internet Protocol. These
questions that people often ask are heard all over these days, but our
answers will help explain much about this new phase of keeping in touch
with others.
What exactly is IP telephony?
IP telephony is a term that refers to VOIP technology or Voice over
Internet Protocol. It is essentially the routing of voice conversations
over a network, such as the internet, or any IP based interface. IP
telephony, Internet telephony, Voice over Internet Protocol, VOIP,
Broadband telephony, Broadband phone, and Voice over Broadband are all
terms that relatively refer to this in the same way. If someone
mentions any of those terms, they are likely referring to the notion of
IP telephony. It is a growing aspect to communications, too, and many
people are starting to use it in their homes to help with their
communications aspects.
Where did IP telephony come from?
IP telephony is a commercial evolution of the 1973 project called
"Network Voice Protocol". Network Voice Protocol was a computer
networking project that was used to transport human speech patterns
over communications networks. It was developed by internet researcher
Danny Cohen of the Information Sciences Institute and was created to
demonstrate that it was possible to develop a feasible blueprint for
two-way voice communications over a digital network. The Network Voice
Protocol project was used to send speech between sites on the Advanced
Research Projects Agency Network or ARPANET. ARPANET is a United States
Department of Defense project designed to produce a global network. It
also became an ancestor of the internet.
Isn't a VOIP user "handcuffed" to an internet connection if they want to use the phone?
Certainly a drawback to the VOIP system is its reliance on internet
connection. This reliance on an entirely separate service can make
using VOIP telephony equipment seem to be quite complicated, at times.
The quality of the connection through the VOIP system is also very
reliant on the quality of the internet connection, lending to a
distinct relationship between the internet connection and the phone
connection that many users regret. VOIP systems can, however, use
conventional phone connections for connectivity and can use other
business grade network systems like a T1 connection in some cases. Many
business providers, in fact, only hook the system up to a T1 connection
to enable permanent connection to their network.
Just how reliable is IP telephony, anyway?
As conventional landline phones are connected to telephone company
phone lines, they may actually be kept going in the event of power
outages or other occurrences that may interrupt the service. Most
household VOIP broadband services, however, rely on a modem connection
or other powered services to make the phone work. In these cases, a
VOIP phone may not be the most reliable service you can have. On the
other hand, there are many options you can take to create a more
reliable service for your phone so that it will not be interrupted by
power outage or other issues.
What are some major VOIP or IP telephony providers?
There are many providers that are hopping aboard the VOIP bandwagon.
Commercial use VOIP providers include Broadvoice, Primus Canada,
AT&T CallVantage, Skype, SunRocket, Lingo, VoicePulse, VOIP.com,
Vonage, and even Yahoo Messenger. Many of these services also have a
phone package for home users that enable the same great service to take
place within a home setting for Voice over Internet Protocol telephony.
