How VoIP Works — Busting Out of Long Distance Rates

VoIP is the newest advancement in audio communications technology, and has a
variety of different applications that make it useful. VoIP stands for Voice
over Internet Protocol, and how VoIP works is truly quite revolutionary
because it streamlines the time of action of sending analog audio signals by converting
them to a much easier to send digital form for transmission.
To understand how VoIP works, you’ll need to understand the basic concept
behind regular analog audio communication in addition, since this is the precursor
for VoIP. Analog phone calls are truly made via fiber optic networks by
digitizing your voice communications for sending the signal across thousands of
miles, but once it gets to the final destination (a home or office phone, for
example), the signal is once again converted to analog.
During these calls, the switches keep open already while there is dead air and
no conversation is taking place; the circuit is also open in both directions
already when only one party is talking and the other is listening. This isn’t
terribly efficient, and slows down the communication of information
considerably.
Packet switching streamlines VoIP
VoIP works on a different assumption — instead of circuit switching, data
packet switching sends and receives information only when you need it instead of
in a continued stream. It also sends the information packets along at any rate open
channels are obtainable instead of a dedicated line, which is much more
efficient. The information is simply reassembled at the source.
The payload of each packet has a destination coded into it calculating the
ultimate destination. When the computer at the other end receives all of these
packets, it will reassemble the information into useable form. This form of
sending audio data is extremely efficient because it always takes the cheapest
route that is also the least congested.
The compression of information and use of multiple routes in order to send
that information over the most efficient route makes sending audio over packet
switching quicker, much less expensive and more efficient. The number of calls
that can be sent is orders of extent higher than it was with the more
traditional analog circuit switching systems.
For companies, the savings in long distance charges can be in the hundreds or
already thousands of dollars per year. If companies also make extensive conference
calls, VoIP makes already more sense when combined with conferencing options such
as document sharing in systems offered by companies like Voxwire and iVocalize.

Different types of VoIP calling are obtainable

  • The most commonly used VoIP system is from one computer to another. To set up this kind of service, you will need to have a sound card installed in both computers along with microphones and Internet connections. For functional purposes, you’ll want a broadband connection or DSL — a dial-up modem will be so slow the sound quality just won’t be that good. Aside from that, all you need is a software package that can set you up with everything you need to use VoIP to make phone calls to whomever is also set up with the same system.
  • You can also invest in IP phones if you want something that looks just like your standard analog telephones but with VoIP connectability. These simply replace the old-style RJ-11 connectors with Ethernet connectors (RJ-45). Hardware such as routers and the needed software are built right in.
  • Analog telephone adaptors (ATA) permit you to connect a standard telephone to your computer Internet connection in order to take advantage of VoIP options. ATA converts analog signals to digital so that it can be transmitted properly via the Internet.
  • The newest option on the market is the Wi-Fi phone, which uses short-distance Internet transmission of VoIP to replace cell phones calls. Wi-Fi broadcasts over the radio spectrum to cover short range areas for users in certain areas, and these “hot spots” have popped up across the U.S.

The upshot of VoIP is that standard long-distance charges may soon become a
thing of the past. As more and more consumers turn on to VoIP and broadband
connections make it easy and inexpensive (in addition as functional) to make phone
calls over the Internet, fewer individuals will be willing to pay high rates to
make a telephone call they can make for free or next to nothing via their
computer.
VoIP saves you money on long distance
There’s no by-the-minute charges with VoIP, no set-up fees, and no “time of
day” or overages. That’s the great thing about VoIP plans. You just pay a
monthly fee and get to make all the calls you want over your computer for one
monthly fee. It’s so simple and elegant, and it’s the solution that everyone’s
been wanting and waiting for far too long.
You don’t have to wait for a certain time of day of day of the week to make
telephone calls with VoIP. There’s also the advantage of being able to use your
VoIP connection from anywhere — remember, you’re not tied to a phone jack to
use your number, but an Internet connection, so you can call from anywhere with
many calling plans.
Some of the companies that offer excellent VoIP plans with unlimited calling
are listed below with their most popular options:

  • Vonage currently offers a $24.95 per month unlimited VoIP package to anywhere in the U.S. or Canada. It includes voicemail, call forwarding, three way calling, call waiting and caller ID.
  • Packet 8 can provide unlimited VoIP for $19.95 a month in the U.S. and Canada with a variety of features like call waiting and three-way calling, and can also give you video phone service for about $29.95 per month.
  • AT&T’s CallVantage provides the usual U.S. and Canada broadband calling with voicemail, call waiting, etc. along with email, a call log and a ‘do not upset’ option, all for $29.99 a month. You also get to keep your phone number for life, no matter where you go — a great characterize for some who move around a lot.

VoIP in web conferencing packages
VoIP is used in almost all web conferencing sets as an different to
standard conference calls, and looking into these packages will give you an idea
of some ways to combine VoIP with extras such as white boards, document sharing
and video. For less expensive options, many companies can provide strictly audio
VoIP conference calls combined with text messaging and document sharing without
video.
Some companies that offer VoIP in web conferencing packages separate from
video conferencing are:

  • Voxwire offers voice communication with features like auto-queue, mute options, individual speaker adjustments and moderator controls along with a “follow me” browser system so that all participants can view a shared desktop. Two persons can use VoIP for $9.95 a month, or up to ten in a conference ecosystem for $29.95 per month.
  • VoiceCafé provides similar sets with a wide range of options that vary from packages with VoIP capability for five people at a time on a conference call to up to 500 in one conference call, all for a flat monthly fee. The prices vary depending upon what package you choose, and there are several.
  • iVocalize offers VoIP along with Internet conferencing options like PowerPoint presentation capabilities and presentation recording for future playback. They also provide optional Unicode translation in thirteen languages. The most basic VoIP package begins at $10.00 a month with a prices going up incrementally depending upon your needs and how many will be involved in your conference calls.

It is obvious that conference calling in addition as standard long distance
calling will be changing greatly in the near future as VoIP changes the
scenery of telephone service. “Land lines” for long distance calling will
ultimately become out of use as broadband becomes more shared and makes VoIP just
as standard as any other kind of telephone call.
And with the greater portability of soft phone options built into laptops and
the use of ATA phone adapters, the use of VoIP in the average home will arrive
sooner instead of later.
