Top 5 Free VOIP Providers For Making Free Calls Worldwide

January 10th, 2010



1) Raketu- Pretty decent service which offers FREE calls to 42 countries. I am rating it higher than VOIPbuster/Discount for the very reason thats its not a clone and it uses a diff technology than skype. Skype uses Supernodes which can be vulnerable to hacking. I covered that issues in my blog earlier. Additionally it integrates with Yahoo, MSN messengers etc.

Benefits: Better technology, Clear Voice, 42 countries FREE, Integrate with other messengers Drawbcks- Haven’t found any yet.

2) Jajah : I tried jajah about 1 month back and with their FREE minutes i made calls to India. The difference between jajah and other VOIP providers is Jajah only allows you to make calls from your phone. That means You need to give your phone number and your calling party number before you can make a call. When you intiate a call Jajah first connect your phone. You pick up the call and then jajah connects to the other party.

Benefits: No software download needed. Just visit their site. No credits needed for free calls. Drawbacks: Have to use a legitimate number before calling. Cant use PC to make call.

3) Gizmo : Popularly known as ” Skype Killer”. This software lets you call anyone in more than 60 countries. The only downside is that you and other party both should be registered with Gizmo and should also register your numbers. I am sure that this project will be successful and in short time the daatabase of people will be built and then its a FREE calling world.

Benefits: Making calls is easier than ever, Killer Application interface, Drawbacks: Requires both parties to register their numbers with Gizmo.

4) Voipcheap – This is the original VOIPcheap and not the UK version of this company. Although VOIPbuster, voipcheap.co.uk uses the same software, i found this software more reliable and voice quality is of high level. This is an straight winner when it comes to making FREE calls worldwide. You can virtually call more than 50 countries on normal PSTN landlines and mobiles in singapore, USA, HK & Canada. With some hacks, you can call from countries which are not listed in FREE list but you have a work around. You need to check my blog for that.

Benefits: Clear voice, You can make calls from your PC. No need to buy any credits from them before making free calls. Allows PC or Phone to initiate call (via Directdial)

Drawbacks: really none.

5) voipraider/ voipbuster: All these companies belong to Betamax GMBH, a European company dealing in VOIP. They offer extremely low competitive rates to many countries but have almost zero customer service.

Benefits:1 or more additional countries (Thailand + mobile) on Voipdiscount. Drawbacks: No customer service. Change rate any time.

I hope this article will benefit you in making Free International Calls

VOIP Broadband Phones – What Should You Know?

December 24th, 2009



The expanded form of VOIP is Voice Over Internet Protocol. The most significant factor that affects the functioning of the VOIP phones is the Broadband Internet Connection, which is a high-speed internet connection and will be used for making and receiving phone calls. As there is a use of broadband internet connection in VOIP phones, they are also known as, “Broadband phones.”

Principle Of VOIP Technology

The main principle of VOIP technology is to transform the voice into digital signals which will be forwarded to the broadband internet. This net connection will then help in the conversion of the digital signals into voice before reaching to the listener.

Bandwidth Required For VOIP Phones

The functioning of VOIP phones depend upon broadband internet connection and the quantity of data transfer by broadband internet connection is directly proportional to the bandwidth speed. In other words, bandwidth is the capability to transfer data in a given span of time.

There are two different types of bandwidth. One is the upload bandwidth, which is the quantity of data sent to the internet, and the other is download bandwidth, which is the quantity of data received from the internet.

It is always recommended to use the broadband bandwidth of 90 Kbps as VOIP telephone calls utilize 90 Kbps of bandwidth for high sound quality. But if broadband net service provider is unable to provide this much of bandwidth then most of the VOIP service providers provide an option of lowering down the voice quality by lowering down the bandwidth to approximately 60 Kbps or 30 Kbps.

Uses Of VOIP Broadband Phone

The broadband phone can be utilized to replace the analog phone line or it can be used as a second phone. The most significant use of VOIP service is to make long distance and internationals calls at very cheap rates.

This feature has proved to be very much attractive for the people and companies that are into businesses at international levels. There are different types of value added services that are offered by VOIP broadband phones like caller ID, call diverting, 3-way calling, call waiting, etc.

The most attractive thing in getting these values added services from them is that they are free of cost. These broadband phone service providers also provide a service of virtual phone number. The use of this virtual phone number is that it possesses an area code from where you generally receive the maximum number of calls, and the rates will be very cheap for the people who are calling you.

Precautions While Using Broadband Phone Services:

Though the use of broadband phone service is very advantageous, you should always consider the below-mentioned precautions while utilizing the broadband phone services.

1 – As it is very clear that broadband phones work by the transmission of digital signals by using broadband internet connection, it is always suggested to go for a high quality broadband connection else it will affect the quality of the phone calls.

2 – You should always be ready with a back up in case of break down of power supply and internet connection as this break down will stop the functioning of broadband phones.

3 – It is the responsibility of the users to update the VOIP service providers regarding your current address so that they can assist you at the time of emergency through their service of 9-1-1.

It is always recommended to search for the functioning of technology, benefits, and limitations of the VOIP phones while planning to have a broadband phone connection so that your investment should not go into drains.

VOIP Phones – An Affordable Broadband Communication Technology

December 4th, 2009



Cordless VOIP phones have become increasingly popular because they afford the caller a bargain-priced way to communicate. Unlike conventional international and long distance telephone calls where you pay quite high charges per second, the VOIP call will only cost you accordant with what you pay for your internet access. So if you have flat rate monthly internet billing, then you can make as many calls including interstate locations as much as you want without being billed for any further costs.

Cordless Skype telephones give the user extra leverage when it comes to communication due to the fact that the same high speed internet service that is used for voice signals may also be used for other data transfers such as web browsing. With Voice-Over-IP Phones, you are able to do away with numerous bundles of telephone wires and the resultant holes through ceilings.

There are primarily three means to connect a wireless VOIP phone. The most common method of connection is through the use of a regular VOIP phone – this could even be simply a run of the mill mobile telephone handset with VOIP capability – meaning it is able to transmit over the web in lieu of the normal telephone system. They also make VOIP phones via alteration of a normal telephone. In this instance you’ll need an adaptor so that the regular phone can be made to transmit digital audio signals via the net. A third type is the soft phone. In this example you’ll use your computer speaker and headset as the phone. The pc will also have a program that will enable you to transmit the resulting digital audio signals over the internet.

It is extremely critical to use a high speed ethernet connection for your VOIP Phone. A low speed web connection will cause your connections to break very often, resulting in inferior voice quality. If you are buying a usb VOIP Phone from a shop, ensure that you have access to fire and emergency services such as 911.

There are many things to think about if you are using a wifi skype telephone. You’ll need to consider the communications standards that the phone offers. You will also have to determine if your wireless and Web connections are able to support them. Again, you’ll have to look into whether it comes with features like conferencing so you are able to talk to more than 1 people at a time. It might be practical to get a wireless Voice-Over-IP Phone with a LCD or LED screen so you are able to place calls or otherwise make use of the phone in dimly lit areas. You’ll need to find out what standards employed by the Voice-Over-IP are directly supported by your computer. This is vitally critical if you are using an adaptor to make the telephone work. You’ll also need to figure out this specification if you plan to use a Voice-Over-IP Phone handset.

Wireless Skype phones provide a very cheap way to communicate with family. You’ll spend much less money to talk interstate or overseas.
