A guide to VoIP

What is VoIP? Voice over Internet Protocol (VoIP) is the ability to transmit voice over the Internet to either a receiving computer, telephone or even a mobile phone. VoIP phone is becoming the popular worldwide telephone service for both consumer and the business communities. VoIP works by using a network technology known as Packet Switching Network whereas landline telephones use the Circuit Switching Network. This is referred to as the Public Switched Telephone Network.

What’s the difference between VoIP normal phones?

The main difference between Packet Switching and Circuit Switching, is that Packet Switching uses (data) or Packets and sends them over the Internet while Circuit Switching is accomplished by using electrical circuits to make a telephone connection. Circuit Switching is like the old switchboard operators, frantically trying to connect the right caller with the receiver. Packet Switching is used to transfer data all across the Internet including E-mail. Packet Switching converts audio formats into data packets and transmits them over the Internet, then reassembles them on the other person’s phone or computer in real time. By using a Broadband Internet Connection, microphone and speakers a conversation can take place similar to traditional telephone.

VoIP phones have been round for sometime, but increases in technology it is becoming increasingly popular. Several years ago many applications were available offering some form of free VoIP phone service. Majority of these have gone or now charge a fee for the use of their service as VoIP phone provider. Moreover, VoIP is developing higher standards of quality every day, and it has proved that it is a viable force for telecommunication for the future.

Who is providing VoIP phone service?

Telephone and Internet service provider companies are expanding to allow for monthly VoIP phone services. Companies such as AOL, Verizon and Sprint have VoIP phone offerings. Recently eBay has joined the ranks of VoIP phone service providers by purchasing skype VoIP software, with its vast membership base the VoIP message will soon reach the man on the street.

What’s special about VoIP?

Instant messaging programs such as MSN massager have been using VoIP technology for years. Now, most of these messaging programs come with voice enabled features which allow you to call a member of your buddy list. By using a microphone and speakers, you will be able to converse anywhere in the world, by VoIP and your Instant Messaging program.

With instant messaging VoIP incorporates different areas into one program. With your voice enabled programs, you can hook up a digital camera,web cam and use video, while you are speaking on your microphone and listening to on your speakers, and you can type back and forth with your chat program. You could even write an email at the same time. The potential for VoIP phones use is nearly limitless.

VoIP has this unique ability to integrate many forms of telecommunication applications into one package can handle data, audio, video, E-Mail, and web based applications simultaneously. This makes VoIP an incredible boost to business world and provides a cost effective choice of telephone service.

VoIP phone service providers are increasing in popularity with many people discovering all of the benefits available to them by switching from using their land line telephones to VoIP service. First, VoIP phone services costs significantly less than standard phone service, and this is a great attraction for bringing in new customers. Many VoIP phone plans will let you make unlimited long distance calls or provide you with a plan for very inexpensive rates. Many of the features that are often included for a fee with traditional phone service are often included for free with VoIP services. Features such as Call Waiting, Call Block, Call Forwarding, Conference Calling, Voice Mail are usually charged as extras by the traditional phone companies but these are usually free with the VoIP phone packages.Another benefit to VoIP services is that you can usually keep your existing phone number, or allow you to select a new area code. The means if you select an area where most of your friends and family live, a call to you will be treated as local call. For a remote business VoIP service can give the perception of having multiple office locations.

What’s the future for VoIP

Make no mistake about it VoIP phone services is a the emerging contender in the telecommunication world.It is a proven technology, can seamlessly integrate into many existing applications, does not require special equipment anyone with a PC with a microphone and speakers can use the service and it is very cost effective. Talk will be cheap!

Pros And Cons Of Getting VOIP Right Now

You have a telephone, right? You have a computer, right? You want to save money, right? BAM, you are a VOIP (Voice Over Internet Protocol) candidate.

It is inevitable that VOIP will replace traditional telephone service at some point. The only question is when should you jump in?

VOIP is quickly becoming more reliable and receiving wider acceptance. In fact, phone companies are already taking advantage of the technology to provide cheaper long distance rates. Like any emerging technology, however, there are kinks in the system that are still being worked out.

Advantages

VOIP has many advantages over regular phone service. One primary advantage is its low cost. If you have a fast Internet connection (DSL or cable), you can make PC-to-PC phone calls anywhere in the world FREE. PC-to-phone connections usually have a charge, but probably still cheaper than regular phone service.

You can sign up with a VOIP service provider for a monthly fee and get unlimited calls within a specified geographic area. For example, some VOIP services in the United States allow connections anywhere in North America for no extra charge. International calls are charged at a modest rate.

Another advantage is its portability. You can make and receive phone calls wherever there is a broadband connection by simply signing in to your VOIP account. This makes VOIP as convenient as e-mail. When you’re traveling, you simply pack a headset or Internet phone; then you can talk to family or colleagues for next to nothing.

Phone-to-phone VOIP is also portable. Internet phones are small and light enough to take anywhere. When you sign up with a VOIP service provider, the Internet phone or adaptor used by that service is assigned a unique number. This ‘phone number’ remains valid, even if your VOIP service is in Los Angeles and you’re connected to the Internet in London. When plugged into a broadband connection, anywhere in the world, you can make and receive calls as though you were at home .

Features like call forwarding, call waiting, voicemail, caller ID and 3way-calling, are included with Internet telephone at no extra charge. While you’re talking on the phone, you can send pictures and documents at the same time.

Disadvantages

There are a few glitches that still interfere with the technology’s broad acceptance by the public. Lack of continuous service during power outages and emergency calling are the 2 biggest hurdles.

Conventional phone service continues by the current supplied through the phone lineduring a blackout. This isn’t possible with Internet phones. When the power goes, there goes VOIP service. Battery backups and power generators that provide electricity are the current solutions to this problem.

A major concern involves emergency 911 calls. For the most part, VOIP services aren’t useful in emergencies. Traditional phone equipment can trace the locations of calls. Emergency calls are diverted to the nearest call center where the operator can identify your location, in the event you can’t talk. With VOIP, there is no way currently to determine where Internet calls are originating. There is an emerging standard called e911 however, which is attempting to solve this limitation.

VOIP also has sound quality and reliability problems. Data sent across the Internet usually arrives at its destination scrambled. E-mail and documents can be reassembled in the correct order when it arrives. Voice data also arrives scrambled, but it’s more complicated because of the real-time nature of VOIP. Some data packets may have to be dropped when they don’t arrive in time, in order to make voice connections with the least delay. This can cause brief silences in the audio stream.

Distance and speed of the connection determine the amount of data lost. Some networks receive more traffic and thus are more likely to cause audio dropouts. One way to provide high quality audio connections is to create dedicated data paths.

With the incredible amount of work dedicated to VOIP, these disadvantages will no doubt be resolved withinin the next 2 years. It is expected that by then VOIP will have widespread consumer acceptance.

A Brief Intro To VoIP

If you have an ear open to new computer technologies, you are sure to have heard about VoIP. Voice over Internet Protocol (VoIP) is an emerging set of applications which allows you to make telephone calls over the Internet. It is already starting to replace existing telephone networks, with some people and businesses opting to cancel their traditional phone line and use VoIP instead.

VoIP was originally developed to provide voice communication between computer users in different locations. Although it still has this application, it has been further developed into a telephone network in its own right. People using VoIP can call any telephone anywhere in the world and can receive calls on telephone sets connected to the Internet or Local Area Network (LAN).

Background

It all started back in 1995 when Israeli computer enthusiasts made the first computer to computer voice connection. In the same year this technology was developed into a software package called Internet Phone Software. All that was needed to talk to another computer user was a modem, sound card, speakers, and a microphone.

The software digitized and compressed the audio signal before sending it over the Internet in data packets. These voice connections could only occur between computers which had the software installed. The sound quality was very poor — nowhere near the quality of standard telephone connections.

The technology continued to be developed and by 1998 gateways had been established to allow PC-to-phone connections. Later that same year phone-to-phone connections that used the Internet for voice transmission were set in place. These phone-to-phone connections still required a computer to initiate the call, but once the connection was established, the callers could use a regular phone set.

VoIP Today

There are currently many VoIP services available for residential and commercial use. Some of these still rely on PC-to-PC connections but may offer other services such as PC-to-phone and phone-to-phone.

Internet phones are available that plug into the sound card or USB port of a computer. These phones may have number pads and ringers that allow you to use them the same as traditional telephones. The computer can be bypassed completely by connecting a phone directly to a broadband modem (either DSL or cable).

How Does It Work?

The first step in using VoIP is converting your voice into digital data. This is done by ’sampling’ your voice — dividing the analog sound signal into discrete steps that can be assigned a number value. Once your voice is digitized, the data can be compressed.

This compressed digital data is split up into ‘packets’ of about 1500 bytes that can be transferred over the Internet. As well as the voice data, the packets contain information about their origin, their destination, and a timestamp that allows them to be reconstructed in the correct order. Once they arrive at their destination, they are reassembled and converted from digital back into analog so that the receiving party can hear your voice.

In order for voice data to be transmitted without noticeable delays, a broadband Internet connection is necessary. Many households and businesses are already using broadband (either DSL or cable) so adding VoIP is relatively simple.

Broadband - Description : VOIP

Broadband is a general term for any technology that transfers data over a broad bandwidth connection. Such a connection allows for much higher transmission speed and quality than its low bandwidth equivalent.

Broadband technology can be used for a variety of different purposes, including high speed internet access (e.g. Cable, DSL, T1, etc.), and VoIP (broadband phone) connections

Data Encryption - Description : VOIP

Data encryption is the process of coding digital data in such a way that it cannot be read if intercepted by a third party. A user must have a special password in order to gain access to encrypted information.Encryption is used in a variety of internet communication processes, including VoIP conversations. Encryption is especially important for content that is of a sensitive or private matter, such as in the cases of financial transactions and medical prescriptions. 

Data Recovery - What Not to Do

Data recovery is a tricky thing, and if you’ve somehow deleted or had your important files corrupted or lost due to human error, business espionage, faulty hardware or software or any other reason; the good news is that your lost data is probably recoverable. This article will show you a few things NOT to do when an event such as this occurs.

Don’t run the drive anymore, or use the device. (MP3, portable storage, camera card, whatever) If you think it won’t hurt to even just poke around the internet for a solution to this mess you’ve made/found, you’re wrong! Don’t install or run anything on the drive you hope to recover data from. Only access this drive again from a healthy PC with the software solution you’re going to use. Since files are overwritten in the order they’ve been deleted, the last files that have been excised from your drive will be the first to be lost permanently. Even just surfing, with all the cookies and temporary internet files that are always being generated will often doom the process without you even knowing about it.

Don’t use tools that may reside on your computer, such as Scandisk, or a boot record utility, as these will probably overwrite exactly the files you’re seeking to get back.

In short, be careful! Your data may very well be recoverable, as long as you don’t do something to erase it forever! Find a good data recovery software solution, and then follow the instructions to the letter, and you’ll more than likely live to see your lost data return!

Treble your Adsense Income in 60 MInutes

Google’s Adsense is one of the most powerful weapons in website publisher’s arsenal. It enables you to monetize your sites easily and if used properly can generate a very healthy income. However, if you’re not using it properly and maximizing the income you squeeze from it, your leaving money on the table – something we all hate doing.

Boosting your return from Adsense can be done very easily and quickly, and you’ll be amazed by the results.

I ran Adsense on my sites for over a year before I discovered these techniques, and like many people, I though I was doing pretty well. My clickthrough rates and CPM figures were very healthy, and I didn’t honestly think that they could be improved a great deal. How wrong I was. Immediately after I implemented a few quick changes my clickthrough rate more than doubled, and by doing some fine tuning I manged to get nearly three times as many people to click on the ads as had been previously doing so.

The first technique is one that was ‘discovered’ by the amazingly helpful Debs, on SiteSell’s SBI! forums. When I read it originally, it made sense and I decided to goive it a go, but I wasn’t prepared for the immediate impact it would have on my income. It involves making only a few simple changes to the format and positioning of your Adsense ads.

Firstly, forget about using banners or skyscrapers. These ad formats are almost universally ignored by surfers. Why? Because we’ve all been conditioned to recognise a skyscraper or banner as an advert and as these adverts are rarely of any interest, we ignore them. What’s needed is a way of integrating Adsense ads into the editorial on your site as seamlessly as possible. To do this you need to do three things:

1. Use the 250 x 250 rectangle format 2. Make the background color of the ad the same as the background color of your site, or as close to it as possible. 3. Make the ads borderless by setting the border color to be the same as the background color of the ad.

These changes can be made by logging into your Adsense account and creating a custom format. Just select the 250 x 250 ad format, and create a custom color palette. Use the color picker to pick the coor you want. The Javascript is automatically generated at the foot of the page, ready for you to copy and paste into the pages on your site.

Now, you need to position your ads where surfers are most likely to click on them. Research using retina scanning technology has shown that the place that surfers tend to look at first and most often is the top left. I don’t know the reasons for this, perhaps it’s because that’s where we’re used to seeing the most useful search engine results (at the top of the rankings) and search engines are the sites we most often visit, so we automatically look at the same place on other sites.

Whatever the reasoning, as soon as I made the above changes to my Adsense ads, clickthrough rates doubled, immediately.

The second technique is much newer and one which is entirely based on my own experience. Google has recently added a new type of Adsense format, called Adlinks. This displays a series of links on your page in the same style of Ad unit as regular Adsense ads. When a user clicks a link they are taken to a page of adverts that resembles regular Google search results. As a publisher, you are paid every time a user clicks one of those ads.

Adventurous soul that I am, I jumped in with both feet and started to trial Adlinks on my most visited pages as soon as it was launched. I’m using the four links in a square box format, positioned top left of my page content. After a few weeks of running Adlinks alongside regular Adsense ads, it’s clear that the return on Adlinks is about a fifth to a quarter higher than regular ads. There’s no clear reason for this but one explanation may lie in the fact that clicking on an Adlink takes the user to page of ‘results’. When a user clicks on one of these, you are paid for the click. If the user finds what they want, great, if not, it seems that they hit the Back button on their browser and try again, just as you would for normal search engine results. Then they click on another result, and you get paid again. So it’s possible to be paid more than once from the same Adlink click. Now, this reasoning is speculative, but it does make perfect sense in the light of my Adlinks results.

Finally, Adsense has some excellent tracking statistics that allow you to track your results across a number of sites on a site by site, page by page, or just about any other basis you choose. This is a very powerful tool and you should use it to find out which ads are performing best for you and fine tune your Adsense and Adlink ads accordingly.

So you see, by spending an hour or so of your time making a few adjustments to the Adsense ads on your sites, you can very quickly treble your Adsense income. Give it a go, you’ll be amazed by the results.
