Cisco Training Courses: All about Asterisk VoIP Hosted PBX

In today’s world, fast and reliable communication systems are very important. This is why many people are now using the internet and telephone systems in a daily basis and in fact, these tools are even considered as two of the most important communication equipments today.

With the telephone, you will be able to communicate with your family, friends and even your business associates. It provides a fast and reliable way to communicate with people wherever you are in the world. This communication tool is so important that companies today can never survive without it. Almost every homes and large companies today have telephones installed in their homes.

Another tool for communication that is also considered as one of the most important communication tools is the internet. The internet provides a cheap way to communication with your family, friends and business associates. Through emails and instant messengers, you can instantly send letters and chat for free.

Today, the communications industry has made another breakthrough in improving the way you communicate. This system is called Voice over Internet Protocol or VoIP for short, or also known as Internet Voice. This communication system is very much like your conventional landline telephone system but much better. In fact, many people are now considering getting rid of their old conventional landline phones and convert their subscription to VoIP.

This is because VoIP offers a lot of services and benefits to their clients that conventional telephone systems cannot. First of all, VoIP uses the internet to transmit and receive data. This means because it uses the internet, your voice is converted to digital data and sent to the other end of the line. Because it uses the internet and uses digital data, communication is much reliable, much faster, and also much clearer than conventional landline telephones.

Another great thing about VoIP and its internet usage is that it provides low cost or even free long-distance or overseas calls. Try calling someone overseas for five minutes using a conventional phone and a VoIP phone. You will see that VoIP provides clearer and faster communication. Also, when your monthly bill arrives, you will also observe that the cost of the overseas call made through VoIP is much lower than the same call made with your conventional landline phone.

These are only some of the benefits of VoIP. What if you need a PBX for your company? You will notice that it will usually be very expensive to do this with conventional telephone system. However, with VoIP, you will see that it will be much cheaper and more reliable. IP PBX will work just like a conventional PBX. However, this will be based on VoIP systems and will be connected to the internet to communicate instead of phone lines.

VoIP is now widely available today. VoIP service providers are now advertising their services online and are also offering business VoIP. However, if you want to have your own VoIP in your home and you also want to join the company that provides VoIP, you have to learn how to install different kinds of VoIP.

Voip Companies And Voip Networks Are Increasing The Coverage

Voip Companies And Voip Networks Are Increasing The Coverage

One of the main consumer concerns that slowed the early trend towards VOIP phone services was the concern that phone communication done via Internet would not have enough network coverage to allow for appropriate use for the common individual. When many people think of VOIP, they think of a phone that can only be used when sitting next to a home computer at home, but this is hardly the case, and the available network of areas that can use VOIP continue to grow every day!

VOIP phone systems offer an alternative to the older landline telephone services. There are many large, as well as other smaller local companies, who are involved in providing VOIP service, and as the network size continues to increase, so does the demand for service. While larger cities tend to have better coverage networks for VOIP services than other more rural places, the network of coverage continues to grow, allowing for more and more people to take advantage of VOIP networks.

There are many different options for which network you can hook up with. Much of that will depend on what type of VOIP service providers are in your area. There are many companies that act as service providers, including Skype, VoiceGlo, and Vonage, among many others. Vonage is by far and away the best known of all VOIP services, and has a distinct advantage in that it can offer a full range of services because it has one of, if not the, best network of any VOIP provider.

Vonage is mid range as far as pricing goes, and gives some of the best service. Vonage not only can replace your normal phone line at home, but with the addition of a VOIP phone, you can also have a portable phone to take with you. A VOIP phone has service wherever you can go online with the Internet, and many cities are making plans to increase the numbers of areas where free “wi-fi” will be available, which will do for portable VOIP phones what cell towers did for the cell phone.

So what about VOIP at home? The software for VOIP is online and can easily be downloaded to the computer. Once this is done, you can communicate with any friends, associates, or family that has the same software, but instead of running up the phone bill, you don’t get charged long distance: you just pay for the original service and then from your home your phone service acts exactly as it would otherwise.

You even use the phone, except technically you are calling through the computer instead of an old phone line, which saves you a lot of money if you are trying to save on long distance costs. From any house with Internet and VOIP, you have the ability to call anyone else with Internet and VOIP, and you don’t have to worry about chatting too long, or about what parts of the day, night, or weekend you need to call, because you’re not getting charged.

In that sense, VOIP networks are rapidly becoming as efficient as many of the more traditional phone company networks, and even more so than some cell phones.

Special Considerations for Small Business Phone Systems

Special Considerations for Small Business Phone Systems

Small businesses have special needs, especially in comparison to larger, more established companies. The term “small business” often really refers to “new business”, in that many small businesses that have been around for a while are as large as they are likely to ever become simply because of the type of business they are. Some small businesses, however, are destined to become large businesses. These companies in particular need to weigh the considerations of their unique situation when purchasing a business phone system. Knowing one’s options when it comes to business phones can save a substantial amount of money and time.

If a company is in a physical location that will be able to meet it’s needs for many years to come and their number of employees is well into the double digit range, they may wish to go with a Private Branch Exchange (PBX) system. PBX systems offer increased expansion capabilities and can come with more available features for the end user. Installation expenses for PBX systems can be extremely high, however, and should be factored in any organization’s business phone system budget.

The alternative would be to use a Key System. Key Systems are cheaper and require less in the way of installation expense. Still, they are only expandable to provide service to thirty or forty terminals. For businesses that will eventually require more handsets than Key Systems are capable of supporting, replacement with a PBX system would be inevitable.

The worst case scenario would be for a business to buy a phone system that barely meets it’s current needs only to find that it will have to be replaced soon after. Properly planning for growth will help any business end up with a phone system that can expand with it’s expansion and allow the most value for the overall investment. Like any business investment, phone systems do not last forever, so it is often unnecessary to purchase the very best (and most expensive) system on the market. Still, it does pay to purchase a business phone system that is certain to meet your company’s needs, both now and well into the future.

VoIP 101 (2)

VoIP 101

For those who have never heard about the potential of VoIP, be prepared to radically change the way you think about your current long-distance calling plan. VoIP (Voice over Internet Protocol) is very simply, a method for taking ordinary analog audio signals and turning them into digital signals that can be sent over the Internet.
So what? Well, for those of you who are already paying a monthly fee for an Internet connection, this means that you can use that same connection to place free long distance phone calls. This process works by using already available VoIP software to make phone calls over the Internet, essentially circumventing phone companies and their service charges.
Interestingly, VoIP is not an entirely new thing. In fact, a number of providing companies have been around for some time. But it has only been with the more recent explosion of high-speed internet access usage, that VoIP has gotten any attention. Now the major telephone carriers are setting up their own VoIP calling plans throughout the US, another testament to the potential of the technology.
How VoIP Is Used
While there are a number of ways that VoIP is currently being used, most individual callers fall into one of three categories: ATA, IP Phones, and Computer-to-Computer.
ATA or Analog Telephone Adaptor, is the most common way of using VoIP. This adaptor actually allows you to hook up the phone that is already in your house, to your computer, and then your Internet connection. What the ATA does, is turn the analog signals your phone sends out into digital signals that can be sent over the Internet. Setting up this system is quite simple. It simply requires that you order an ATA (its an adaptor remember), plug the cable from your phone which would normally go into the wall socket into the ATA, and then the ATA gets plugged into your computer, which is connected to the internet. Some ATAs include software that has to be installed on your computer before its ready, but basically it’s quite a simple process. Then you are ready to make some calls.
The next type of VoIP usage utilizes IP Phones instead of your home phone. The IP Phone looks just like a normal phone, with all the same buttons and cradle, the only difference is that instead of having a normal wall jack connector, it has an Ethernet connector. This means, that instead of plugging in your IP phone to the wall jack like you would with a regular analog phone, it gets plugged directly into your router. This option allows you to circumvent your personal computer, and it also means that you will not have to install any software, because its all built in to the handset. In addition, the fact that Wi-Fi IP phones will soon be available, which will allow subscribing callers to make VoIP calls from any Wi-Fi hot spot, make this option an exciting possibility.
The simplest and cheapest way to use VoIP is through computer-to-computer calls. These calls are entirely free, meaning no calling plan whatsoever. The only thing you need, is the software which can be found for free on the internet, a good internet connection, a microphone, speakers, and a sound card. Except for your monthly internet service fee, there is literally no cost for making these calls, no matter how many you make.
For large companies, VoIP also offers some very unique possibilities. Some larger companies are already utilizing the technology by conducting all intra-office calls through a VoIP network. Because the quality of sound is comparable to and in some cases surpasses that of analog service, some international companies are using VoIP to route international calls through the branch of their company nearest the call’s destination and then completing it on an analog system. This allows them to pay local rates internationally and still utilize the same intra-office VoIP network that they would if they were calling someone in the next cubicle over.
Other Advantages of VoIP
While your current long-distance plan covers you for only one location, say calls made from your office, with VoIP, you can make a call anywhere that you can get a broadband connection. That is because all three methods above, unlike analog calls, send the call information via the Internet. This means you can make calls from home, on vacation, on business trips, and almost anywhere else. Anywhere you go, with VoIP you can bring your home phone along with you. In the same way, computer-to-computer connections mean that as long as you have your laptop and a connection, you’re ready to go.
There are also some nifty benefits to having your calls transmitted over the Internet. For example, some VoIP service providers allow you to check your voicemail via your e-mail, while others allow you to attach voice messages to your e-mails.
How VoIP Works
The current phone system relies on a reliable but largely inefficient method for connecting calls known as circuit switching. This technique, which has been used for over 100 years, means that when a call is made between two people a connection is maintained in both directions between callers for the duration of the call. This dual directional characteristic gives the system the name circuit.
If, for example, you made a 30-minute call the circuit would be continuously open, and thus used, between the two phones. Up until about 1960, this meant that every call had to have an actual dedicated wire connecting the two phones. Thus a long distance call cost so much, because you were paying for pieces of copper wire to be connected all the way from your phone to the destination phone, and for that connection to remain constant throughout the call. Today, however, your analog call is converted after leaving your house to a digital signal, where your call can be combined with many others on a single fiber optic cable. While this system is certainly an improvement over the past copper wire system, it is still quite inefficient. This inefficiency is due in part to the fact that the telephone line can’t distinguish between useful talking and unneeded silences. For example, in a typical conversation while one person is talking the other person is listening. Thus the current analog system uses roughly half its space sending useless messages like this silence. But there is also more information, even down to pauses in speech, which under a more efficient system can be effectively cut out rather than wasting the circuit space. This idea of only transmitting the noisy bits of a telephone call and saving a great deal on circuit space, is the basis of Packet-Switching, the alternative method to circuit switching that the VoIP phone system uses.
Packet-Switching is the same method that you use when you view a website. For example, as you read this website, your computer is not maintaining a constant connection to the site, but rather making connections to send and receive information only on an as needed basis (such as when you click on a link). Just as this system allows the transfer of information over the Internet to work so quickly, so also does it work in the VoIP system. While circuit switching maintains a constant and open connection, packet switching opens connections just long enough to send bits of data called packets from one computer to another. This allows the network to send your call (in packets) along the least congested and cheapest lines available, while also keeping your computer or IP phone, free to send and receive messages and calls with other computers. This way of sending information, not to mention data compression, makes the amount of information which must be transmitted for every call at least 3-4 times less for VoIP than the exact same call in a conventional telephone system. For this reason, VoIP is so much cheaper than conventional calling plans.
The Future of VoIP
While most analysts believe it will be at least a decade before companies and telephone providers make the full switch to VoIP, the potential for the technology’s use today is already quite astounding. A report by the Forrester Research Group predicts that by the end of 2006, nearly 5 million U.S. households will be using VoIP phone service. With the savings and flexibility that the technology already offers, and new advances just ahead on the horizon, we can expect those numbers will only increase in the future.
