How VoIP Works — Busting Out of Long Distance Rates

admin — Fri, 26 Mar 2010 22:05:32 +0000

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 actually quite revolutionary
because it streamlines the process 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 as well, since this is the precursor
for VoIP. Analog phone calls are actually 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
instance), the signal is once again converted to analog.

During these calls, the switches remain open even while there is dead air and
no conversation is taking place; the circuit is also open in both directions
even 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 premise — rather than circuit switching, data
packet switching sends and receives information only when you need it instead of
in a constant stream. It also sends the information packets along whatever open
channels are available rather than 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 determining 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 magnitude 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
even thousands of dollars per year. If companies also make extensive conference
calls, VoIP makes even 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 available

The most commonly used VoIP system is from one computer to another. To set up this type of service, you will need to have a sound card installed in both computers along with microphones and Internet connections. For practical 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) enable 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 (as well as practical) 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 disturb’ option, all for $29.99 a month. You also get to keep your phone number for life, no matter where you go — a great feature for some who move around a lot.

VoIP in web conferencing packages

VoIP is used in almost all web conferencing services as an alternative 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 environment for $29.95 per month. VoiceCafé provides similar services 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 as well as standard long distance
calling will be changing greatly in the near future as VoIP changes the
landscape of telephone service. “Land lines” for long distance calling will
eventually become obsolete as broadband becomes more common and makes VoIP just
as commonplace as any other type 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 rather than later.

VoIP or voice over protocol is one of the latest innovations in communications technology. The main difference it has with the old telephony system is that it uses data packets while the old telephony system uses switch boards.

In case you are not familiar with switchboards, imagine your call being routed to an operator before it reaches the person you are calling. That illustrates how a switchboard works. VoIP uses data packets that are sent and received via the internet. Hence, the basic equipment you will need to enable VoIP is a modem because this is the main device that allows you to get an internet access.

VoIP products come as trunk or hosted. If you are still wishing to use your old telephone device while utilizing VoIP at the same time, you will need to purchase a gateway from VoIP vendors. The gateway comes in a data packet that looks like a box. You would have to connect this to your conventional telephone or fax machine to enable VoIP. However, if you have an IP enabled system, there is no need to purchase the gateway.

There are four ways by which you can make the calls using the VoIP. These include internet-internet, phone-internet, internet-phone, phone-phone. If you are making a call towards a phone, it can be a regular, non-VoIP phone. Otherwise, the recipient of your call also needs to have a VoIP-enabled device. If you are making a call through a computer, you need to have a head set and a VoIP software program. If you are making an internet-internet call, the computer you are calling to must also have the same software as you have. Examples of this software are Skype, that of Yahoo, MSN, etc.

VoIP Technology, How Does It Work?

VoIP, which stands for Voice over Internet Protocol, is a protocol that has been optimized for transmitting voice via the internet or through other packet switched networks. VoIP carries telephony signals as digital audio that are usually reduced in data rate with speech data compression methods, encapsulated in a data packet stream over IP. In other words, VoIP is the routing of vocal conversations over the internet, or any other network that is IP based. VoIP is also known by other names including Internet telephony, IP Telephony, and Broadband telephony.

VoIP services can have two types of public switched telephone networks (PSTN):

1. Access numbers – the caller is required to key in the extension number of the VoIP user

2. Direct Inward Dialing (DID) – directly connects the caller to the VoIP user.

One of the great aspects about VoIP is that it has the ability to facilitate tasks and provide services that a more traditional PSTN might have difficulty implementing, or may charge more for. Some examples of services that VoIP features include:

• VoIP makes it easy to add an additional telephone line for a home or office, because VoIP has the ability to transmit more than one phone call down the same telephone line connected to broadband.

• VoIP automatically comes with popular phone features such as call forwarding, caller ID, automatic redial and 3-way calling. All of these features can be included in a traditional phone line, but usually each service has an additional cost.

• VoIP already has security in place such as digitizing and digital transmission, which traditional phone lines can sometimes struggle with.

• VoIP phones can work form any location that has a stable and fast internet connection.

• VoIP can integrate with other services that are available though the internet including message or data file exchange, video conversation, managing address books, audio conferencing, and so on.

As you can see, there are many features you can enjoy with VoIP. Furthermore, on the whole, VoIP tends to be the cheaper telephone service in comparison to a traditional phone line. However, regardless if you use a VoIP telephony, or are called by an unknown VoIP user, you can still find out more about a phone number and who it belongs to here.
