Unlike voice over IP, you can use it to call both fixed lines and mobiles and not get charged a penny. Just go to the site and fill in your name and email address. There are no contracts or deposits required. In exchange, you will have to give it information about your interests, and you will be shown advertisements related to these interests while using the software to make phone calls. However, you won't be downloading malware or adware because you only get shown the ads when you make calls or when the application is open.
2. Call other countries. You can also use the application to call other countries outside of the seven free countries, but you will be charged a substantially lower rate than the phone company charges. For example, it only costs 1.7 cents per minute to call India and most other countries.
3. Make calls, do conferences and instant message. After you've downloaded and installed the program, start it up. The interface looks just like a phone. To make a call, you simply dial the numbers. If you wish to make a conference call, click on “Conference” and “Add.” Then click the name or dial the number of the person you want to add to the call. To instant message, you can simply click “Chat” and then click on the name of the contact you wish to chat with.
