The Rebtel Phone Client is a new product by Rebtel, allowing you to make calls from your PC entirely through Rebtel. This functionality replaces our previous PC Calling solution through Skype. With the Rebtel Phone client, you can make calls, add credit, view your account history, add contacts, import contacts, and more, all from the comfort of your PC! Don't forget that all calls made from the Phone client to other Rebtel apps (such as our Smartphone applications) are entirely FREE of any Rebtel cost.
