Using voice on Facebook is a means to make communication more fluid between you and your buddies or business contacts, and also to save on cost. TringMe is a rich VoIP service that has the particularity of offering Internet calls through a softphone that is web-based; meaning that you don't need to download and install any application. It is loaded in a web page, over Flash. This makes it easy to integrate into Facebook.
The application is rather rich with features that are quite handy for a place like Facebook: it lets you make and receive phone calls, send SMS, allows callers to leave voicemails, and gives you TringMe widgets to place on your profile page on which your contacts can click to call or SMS you. These widgets are commonly referred to as click-to-call widgets.
