After a few hours of free land calls, you will not be able to do them anymore. Even if the user you are calling to is also a registered and active Gizmo user. This software seems to have a very arbitrary policy about who can call to landlines for free and wo can not. I'm going to renew my Skype out credit. At least, with Skype, i can count on clear using rules. Even the male voice that warns you to buy call out credits is erratic. Sometimes it appears and others it will just shut off your connection. With Skype starting to allow free calls to landlines (in France it's now possible), i suppose that Gizmo will become vaporware.
