VoIP in Different Countries

admin — Tue, 30 Mar 2010 14:40:05 +0000

The popularity of VoIP is grows rapidly. Voice over Internet protocol is changing the existence of conventional phones. Many PSTN or Public Switch Telephone Network is switching their phone to Voice over Internet Protocol. It makes the use of VoIP is increasing significantly. There are different legal issues coming from different countries regarding to this growth technology of mass telecommunication services.

In the United States, the Federal Communications Commission is requiring all interconnected VoIP service. The aim is to comply with traditional telecommunication services and providers. VoIP in the U.S. is required the support providers to the local number portability. The growth of this technology in U.S. is very rapid. It is because many people switching their use of PSTN and conventional phone service to it, even though VoIP is not covering the emergency phone service, such as 911 services.

On the contrary with the growth in U.S., in India and Guyana, VoIP is being prohibited. The government does not allow this technology is being use in the country. The India government is restricting the use of this technology only for the retail commercial sales only and it is only for the long distance service. In Ethiopia, it will be assuming as criminal offense if using Voice over IP. It is because the Ethiopia government is monopolized the service of telecommunication.

Japan is known as the country with high technological influence. All telephone lines are covering with the VoIP technology. Moreover, the IP telephony was being signed as the telephone numbers since 2003. Later, this IP telephony is covering the service of video phone or video conferencing services. Responding to several complaints, Ministry of Internal Affairs and Communications of Japan is regulating the IP telephony over Japan because telecommunication is very important in people live.

VOIP – Talk Easy, Without Worry About Money

admin — Mon, 29 Mar 2010 06:40:51 +0000

Those were still the early days of the entry of VOIP in the market. Still an esoteric term to many of us. Not so much today. Once feared and revered as an elite technology that only the experts could make head or tail of, it has of today, become an organic mass system of means of communication. It would not be an overstatement to say that VOIP is leading the way in digital communication.

To cut through the rhetoric, what we know is that VOIP refers to Voice over Internet Protocol. This technology converts spoken sounds into digital signals. This allows the voice to be transmitted over a network such as the internet. Your voice is transmitted as sound data packets across the internet to the receiver at the other end. The internet should be broadband or high speed connection. Apart from this, you will require a cable modem or other means of wireless services, a phone equipped with this facility or a special software inside it for this purpose.

There are also a few minor problems with these services such as failure to function during a power outage, especially as when your service provider may not offer backup power for these situations.

VOIP technology has revolutionised the way calls are being made and billed around the world.
It has made talking to anyone around the world as easy as surfing the internet. and this means of telephony often costs you nothing more than than the rate of a local phone call.

Certain things to be kept in mind while using this service: Your service provider may charge you for calls outside your area, so make sure to check the terms of service for the same. You may also avail these services at flat rates as offered by some providers to be able to make long-distance calls at the lowest rates you would have ever imagined. These services may be availed with either your traditional handset phone or with a microphone over the Internet.

Accessibility at economic rates is no more an issue with VOIP.

The Different Stages That Lead to VoIP Service

admin — Mon, 29 Mar 2010 01:46:44 +0000

VoIP service is an ideal means of sending telephone calls over IP networks. The Voice over IP works on the principle of converting analog signals to small packets of digital data and then sending them over a broadband internet connection that ultimately connects the users with the service providers. There are several advantages of using this service. The main reason why people acquire this connection is quite straightforward; the expenses incurred while making long distance calls using such a service is low as compared to the traditional phone line connections.

As VoIP service is based on the transfer of digital data, so the service provider can actually do a lot with this technology. Among the most prominent of the services that a service provider can provide are storing of incoming voice mails in the mailbox, sending of email attachments and 3 way calling. Let us consider a scenario in which the user is busy and wants not to be disturbed by any telephone calls. In such situations, the incoming calls can be stored in the voice mail of the subscribers. A person can also send a voice mail as an email attachment which can be accessed on a computer. Then there are plans where up to three people can involve themselves in conference calling. In fact, calling through Voice over IP is far from restricted. The service allows the user to talk to the entire family in one call. Then there are also the options of sending images, videos and voice to people with whom a person is conferencing.

The internet does not differentiate between calls made to a person living next door from calls to people living in another part of the world. The call charges remain the same; such is the benevolence of the VoIP phone service. It is the benefit in price rates that makes people opt for this service in the first place. Moreover the technology is simple and one only requires some simple tools to access the service. An Analog Telephone Adapter (ATA) is provided by the VoIP service provider. This tool helps to convert analog voice to digital samples by use of Analog to Digital Converter. These digital samples are then compressed by the digital signal processors (DSPs). The DSPs make use of codecs for compression and eventually segment ‘voice signals’ to frames that are then stored as ‘voice packets’. The final process involves transfer of these packets in compliance with Voice Communication Protocol or Session Initiation Protocol (SIP).

When these packets arrive at their destination, they have to be decoded; the entire process is carrier out, albeit in a reverse order. The IP packets are decapsulated in compressed data forms. These data are then decompressed to retrieve the original data making use of the same codec that was initially used to perform the compression. The data is then sent through a digital to analog converter that converts it to the original analog voice format for the listener to hear the voice distinctly. So, VoIP service is actually based on a very simple format but requires fast internet service to ensure an effective and soothing calling experience. This becomes all the more important in the context of business VoIP service, wherein the quality of calls becomes a yardstick in determining the expertise of a particular organization.

Small Business Telephone System with VoIP

admin — Sun, 28 Mar 2010 13:41:46 +0000

If you are changing your small business telephone system from a traditional dedicated fixed landline to the newer VoIP technology, there are some things you need to have in place to change successfully.

1. Internet Connection

To route your calls over the Internet instead of over the existing telephone fixed landlines, you need to have a powerful Internet connection and equipment to connect and communicate with.

If your small business is using a DSL or cable modem for your Internet connectivity, you need to research the bandwidth needed for of VoIP communications (Voice over Internet Protocol).

If you are one of 1-2 employees, then DSL or cable should work fine to meet your needs. DSL and cable modems are not ideal for VoIP, but they do work acceptably well for a very small office of just one or two people.

If your office grows to more than 2 users, your small business telephone system needs to grow also. It is time to consider a more robust Internet connection.

The standard DSL and cable modems offer you a quicker download than upload speed. This generally works fine for general computer usage, but it won’t work so well for voice communication.

So, you will need to make sure that your Internet connection can support both the upload and download speeds that you need to have clear and consistent voice communication.

2. How Much Bandwidth?

The industry standard is enough bandwidth for about 1/3 rd of your employees to be on the telephone at the same time … so if you have 30 lines, you should then have enough bandwidth for 10 to be used at any one time. With a business of this size, your small business telephone system will usually require a T1 connection to the Internet.

One of the best things you can do is to work with a provider who can support both your VoIP and Internet connection needs. This will insure that you have the bandwidth necessary to get both your calls and data needs taken care of.

3. Hub vs. Switch

In addition to bandwidth to the Internet, internally you should be using switches on your network rather than hubs. While hubs are fine for electronic data transmission, the transmission of voice over your network necessitates the need for switches to be used.

4. Media Gateways

If you already have a small business telephone system in place, such as a small PBX system, you can purchase a device called a “media gateway” to connect your existing phone system to the Internet without having to replace all of your phones and equipment.

This will save you money from the equipment that would have to be replaced to upgrade to VoIP services.

Moving your small business telephone system over to VoIP requires some pre-planning and consultation with an Internet provider. An experienced provider can offer the equipment and the know-how to make your move to VoIP quickly and without any inconvenience for your employees.

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 Requirements List

admin — Thu, 25 Mar 2010 05:50:57 +0000

Voice over Internet Protocol, or VoIP as it is commonly called, is a revolutionary technology that has created an upheaval of sorts in the domain of long distance communications. End users can now use their personal computers to talk to friends and relatives – who could be located in another part of the globe. A reliable broadband connection is used for the purpose. The need for conventional telephone lines can be done away with; low cost calling made available through IP telephony solutions is increasingly taking the place of traditional phone networks among residential as well as corporate users.

However, certain requirements need to be met for the most satisfactory use of this high-end technology. The equipment used, for one, has to be of the highest quality. Broadband connection in a computer is necessary for good audio quality, for instance. The experience can also be optimised using PC speakers and microphones.

A basic VoIP requirements list has to be in place for users to make the most of the VoIP phone services. As is well-known, the flexibility of voice over IP makes it more user-friendly as compared to traditional telephone networks. Users are able to make quite a few calls over a single connection. A stable Internet connection is all that is needed – and one can make calls from almost anywhere in the world. Innovative features include video integration, fast and efficient exchange of data files, and audio conferencing. Quite a few security features are in place; and users can be sure of security of their calls. Other functionalities found in PSTN networks are also found in IP telephony. These include caller ID, automatic redialing and call forwarding. And with the latest trends in technology, it has become easy to make VoIP enabled calls through mobile devices as well.

VoIP security is not that difficult to implement. Quite a few voice over IP solutions are supported through encryption which make them very much reliable and user friendly. Security is also implemented through patented audio codecs and compression techniques.

Moreover, one should ensure that the broadband connection through which the calls are routed are not congested. This rules out voice drop-outs and long delays.

One can say that the VoIP phone is perfect for quite a few people – from frequent travelers, bored housewives to high-end professionals and busy executives. People who are not near to any fixed line phones or who are traveling the world find these solutions very much affordable and easy to use. With prepaid VoIP phone cards easily available in the market, there are no problems involved in making such calls.

However, when using VoIP products or subscribing to a VoIP service, users must make some provisions against untoward circumstances such as power failures and the services of broadband carriers going down.

VoIP vs PBX – VoIP is Winning the Battle

admin — Tue, 23 Mar 2010 20:43:48 +0000

PBX phone systems were the standard in recent years. These were needed to handle the huge telephony needs of big business. But a PBX is expensive, high

maintenance, and difficult to upgrade when the company needs change.

With the ubiquitous Internet availability, businesses of all sizes have another option for their demanding telephony needs. This is a VoIP system.

What is VoIP?

VoIP is the acronym for “Voice Over Internet Protocol.”

Protocols are the policies for how all things related to the Internet should work. These rules are in place to make sure that people around the globe are working with

the same rules which will help the Internet work best.

So, VoIP is the international standards for how the human voice can be transmitted over the Internet.

Traditional Communications

Consider the fixed landline in your home. Your home phone has a physical wire which is connected to a local telephone pole. That wire then connects to a group of

others at the telephone company’s central office. And finally, the utility has lines to all of their other central offices where lines exist.

When call from your home, the utility sends your call over the lines to the line of the person you are calling using the central office locations.

To make this happen, the phone company uses a Public Switched Telephone Network, or PSTN. This process uses dedicated lines and is relatively costly because of the

need for all of the physical wiring and equipment.

PBX System

An office business has physical lines which come into the building from the utility company, and then physical lines which connect each phone within the building to the

main wired control panel as well.

Traditionally, the business’ PBX or “Private Branch Exchange” would route the calls that come into the building for the different extensions in the system.

While this set up is certainly effective and has its place in certain operations, a small business owner may consider this larger system more complicated to administer.

In addition, PBX is often cost prohibitive for medium or small businesses to purchase, leaving a small business owner without many options.

VoIP Phone Systems

Many offices of all sizes are now moving away from PBX, and embracing VoIP technology.

Businesses can use this newer technology to address their telephony needs with ease of administration, the relatively easy ability to upgrade their systems, as well as

the number one advantage … reduced costs.

This advanced technology allow large, medium, and small business communication to operate over their existing data network.

Where in the past, each phone and each computer had to have its own line to connect to the central network of the building, now only one is necessary.

Just as your computer sends out digital data over the corporate Ethernet network, your voice over IP phone can turn your voice into digital data and send it the same

way and over the same cable.

Also, when wireless networks are available, the transmissions can use the wireless network as well. Cellular phones are one example of this wireless technology.

When you look at VoIP vs. PBX, it is easy to see that VoIP is the technology being adopted now, and large PBX systems are an effective traditional communications

method, but a cumbersome one.

Just as how, fax machines were the way to pass documents from one location to another, but now, we use e-mail … PBX has been the way to route calls but now

VoIP is taking over our telephony needs.

How Do Businesses Benefit From Having a VOIP System?

admin — Tue, 23 Mar 2010 08:54:08 +0000

Voice over Internet Protocol or VoIP technology is capable of cutting costs in telecommunications as well as improving the productivity of a business. Is it right for your business? Here is a look at what kinds of benefits VoIP can bring to business.

1 – VoIP service technology quality has really come a long way since its original inception. VoIP may have been extremely limited in the past, but this no longer the case. Today’s Voice over IP services have evolved significantly, allowing for you to make calls and receive calls using not only standard phones but also IP phones, which are rich in unique features. The sound quality has also vastly improved to the point where many companies have abandoned their traditional telephone systems in favor of the VoIP service.

2 – Using VoIP technology is capable of significantly reducing the costs you pay for telecommunications. The operating costs associated with VoIP services are generally quite significantly lower than when you are dealing with a traditional phone company, because the existing phone infrastructure is expensive to maintain and so are the industry regulations. VoIP providers have lower expenses and so they can charge a lot less for the services that they offer.

3 – VoIP services make your entire phone system a lot more flexible. They make it possible for you to do things which simply cannot be possible using traditional telephone technology. For example, they allow you to bring your phone system along with you since you can plug in anywhere where there is a broadband connection such as at someone’s home or in a hotel room. They also allow you to talk using your laptop, and to get your voice mail and your faxes through your e-mail. With this increase in usability, VoIP services make it possible for you to increase the productivity of your business significantly.

One thing is for sure: VoIP technology is continuing to evolve, and there are a number of compelling new features and benefits that are being developed in order to cater to small business. As an example, dramatic increases in mobility are being provided by combining VoIP services with wireless phone and PDA combinations to decrease cell phone charges while boosting functionality and productivity by a great deal. This is just one example of the exciting things that are happening in terms of VoIP service and technology advancements.

It does not matter what size your business is, VoIP technology happens to be a flexible as well as affordable technology that is capable of offering the same level of sophistication in communication tools that enterprise-size companies are using, meaning that VoIP will allow you to stand up against your competitors in terms of communications technology no matter how large or how small your own company happens to be.
