Discovering How VoIP Works

by Torrie Cantor

You may want to know how VoIP works. After all, this could be the future of audio communications. Now, VoIP could be used instead of phone lines. So how does this technology work? How can you benefit from it?

The Latest Technology – The first step to understanding VoIP is to understand present technology. Our phone lines make use of what is known as circuit switching. Your call is passed through a series of switches until it reaches your recipient and the circuit is opened. In the span of time that you are on the line, the circuit remains open even at times when there is dead air. Even if you are just listening or not talking, the dedicated line is open. Since you are using this particular line, you have to pay for the number of minutes that you have been on it. The dead air is therefore considered a waste that you have to pay for.

VoIP Functions – VoIP functions differently. There is no circuit switching and no dedicated line. What is present is packet switching. With packet switching, your analog audio data is converted to digital packets. These packets have their own addresses so they know where they have to go. These packets then proceed to the nearest router to the next until it reaches the recipient. Once the recipient gets the packets, it is converted back to audio form.

A World of Difference – There is a big difference about how VoIP works. There is obviously no dedicated line. The packets also take different routes depending in which is most accessible. Other routes remain open for the exit or entry of other data packets. There is thus no need to pay for the dead air in which no data is sent. The lack of a dedicated line is what makes VoIP primarily cheaper than traditional phone lines.

Accessibility – Aside from the lesser cost of VoIP, its accessibility is also a major attraction. You can use VoIP whenever and wherever there is internet connection. In our world today, the internet is accessible in almost any place where people are expected to use them. This piece of technology is therefore a big bonus for people who need to travel a lot. You no longer have to spend for long distance calls that can take a big chunk off your budget. VoIP offers the chance to save a lot on the cots of calls.

The Downside – The problem with VoIP though is that it still has a lot of kinks to be worked out. There are still many services that rely on the typical audio communications set-up. One important service for example is 911. When a 911 call is received, there is instant recognition of a caller’s exact location. This is still something that isn’t possible through VoIP. The packets that are sent simply have IP addresses on them but no physical addresses.

Dependence on Technology – Aside from this downside, VoIP is also prone to the weaknesses of computer technology. Your computer could crash or you could lose packets in the process of transmission. This is a big problem if you are transmitting very important information. Your packet data could also fall victim to viruses and hackers.

On the whole, there are more benefits to be gained by how VoIP works though compared to its disadvantages. There is still a need however, to further improve the technology to ensure that users are satisfied and kept safe.

Setting up the Asterisk Phone System at Home

by Amy Nutt

The Asterisk phone systems are Linux-based VOIP PBX Toronto systems. PBX stands for Private Branch Exchange, and this refers to a division of the phone line within a building, be it a business or home. PBX systems are commonly used in businesses. Several phone lines come into the building and then are distributed to several individual extensions spread throughout the company. A few lines out of the building connecting to the phone lines are also part of the system, allowing outgoing calls. You typically have to dial a number, such as 9, to get one of these outside lines. Some people find that setting up a PBX at home is convenient, but not work the thousands of dollars necessary. With Asterisk, this type of system can be set up for relatively little cost.

The Hardware

There are some pieces of hardware that you will need to set up an Asterisk phone system in your home. One is a Linux server with an extra PCI slot. While the program can run on Windows based servers, it does not run well. Linux is a must if you want everything to run efficiently, as the Asterisk system was designed to be run on Linux. Most people find that a dedicated server works best for this application, espcially if they are going to use a Windows based system. The system will need 40 GB of available disk space.

Besides a server, you will also need a Digium Wildcard TDM400P. This is the card that allows you to connect your phones and your phone line to the Asterisk server and the VOIP PBX system. The card has four ports, so you will need to decide how many lines you need. The ports can be configured to be incoming or outgoing, depending on your needs. Incoming ports take the phone line coming from outside of your home and connect it to the system, allowing you to receive calls. Outgoing ports allow you to connect your regular phone to the system, so you can receive calls. If you need more than four ports, you will need to buy an extra card.

Software

Once you have the hardware, you are ready to set up your operating system and install the Asterisk phone system software. The best way to do this and avoid the need for Asterisk consulting as you install the product is to download the ISO of Asterisk@Home. This will begin to install automatically and will reformat your disk if needed, so installing it on a machine that does not have important information on it first is a good idea. There are other ways to set up the system, but they are quite confusing.

Setting up the System

After you have installed the software, you can use the new Web server to view the Asterisk Management Portal. This portal has an interface where you can set up your system. The interface is fairly straightforward and has documentation to help with any questions that you might have.

Once you have the basic setup entered, you will need to add your extensions. This is simple to do on the “Ring Group” screen. Simply add the number of extensions you intend for your home to have. This is also the page where you will configure your voicemail box. To record your voicemail messages, call the chosen extension from a phone inside your system and record the message.

The final step to completely configuring your system is configuring the rules for incoming calls. You can choose whether you want to have the calls go to the phones or an operator, where the caller can choose an extension. Once you have made these choices, you are ready to start using your new VOIP PBX system!

Once installed, Asterisk phone systems work much like a regular PBX system. You simply pick up the phone, dial the extension for an outside line, and make your call! Soon you will forget that you are using a high-tech VOIP PBX system at all as your new phone setup becomes part of your daily life.

The Real Score About Low Rate VoIP

by Torrie Cantor

It’s understandable that every VoIP user would want to look for low rate VoIP. In reality though, all forms of VoIP services are already cheaper than the usual telephone service. Since there are many VoIP providers however, service prices also tend to vary. Depending on several reasons and factors, some providers are really cheaper than others. Here are a couple of things you should know about low rates for VoIP.

Free VoIP Services

Nothing comes for free these days. With VoIP becoming more popular, it is hard to imagine that anyone would offer it for free. There are however some instances when VoIP can be had for free. If you are looking for the lowest VoIP rate, nothing can go lower than free. Here are some points to consider about free VoIP services.

- Providers may offer VoIP for free only as part of a promotional package. The free service may not last for long so you should make sure to check the fine print before using VoIP with a provider.

- There are also other providers that offer 100% free VoIP but only for a limited number of places. In some cases, they may limit the number of hours you can use the service. They may also limit the number of IP addresses you can send to.

- A number of small independent providers may offer free services with few limitations. These may be small companies though and they may not always offer the features that bigger companies offer. Voice quality may also no be as excellent.

Low Rate VoIP

You may think that free services aren’t for you. You may want to have some features that just aren’t available in free services. If this is the case, then you might just want to settle on paying for low rates. Again services, with low rates have a couple of considerations:

- Your decision should not rely on the price factor alone. The lowest VoIP rates don’t always mean that you have a great deal. The low rates may be because a company is not yet well known. It may also be because they really don’t offer good services. Before signing up for VoIP providers with low rates, make sure that they have fairly tolerable services.

- If you choose your features carefully, you may end up getting or paying lower rates. You may for example, not need 3-way call or redirect call features. If you want to have VoIP simply for making basic, personal and local calls, then you can pick the package with less features so you also pay less.

Checking Out a Comparison Site

Compare Deals – The best way to find the best VoIP rate deals is to go to comparison sites. Various sites rate, rank and review VoIP services. Depending on the site you are on, they may also provide the specific features of various VoIP providers.

Make sure you choose a comparison site that actually really tests VoIP. Some sites may only offer reviews based on second hand information. An alternative would be to go to a site that has consumer reviews in it.

A low rate VoIP is not that difficult to find. You do have to spend some time though, finding out if you really have a good deal on your hands.
