Gizmo5 (Formally known as "The Gizmo Project") is a VoIP carrier that allows to place calls to fixed lines numbers for free in a wide range of countries and at cheap rates.
Upon registration, 10 cents is automatically credited to your account so you may test the functionality of Gizmo.
Gizmo also has the ability to accept VoIP-in calls, (by assigning a local number to the subscriber) even if this feature is not active in every country.
In my country, Gizmo is not yet offering VoIP-in, so I use it only for placing outgoing calls.
