Gizmo

Gizmo project uses the Internet connection to make free calls to anyone with a Gizmo account, just like the Skype does. Furthermore, it allows to call other voice networks for free with the one client: Yahoo Messenger, Windows Live, Google Talk and of course Gizmo project. It is also possible to chat with AIM & MSN buddies directly from Gizmo project.

With inexpensive Call-Out feature, user can call any normal phone (mobile or landline) at some 2 cents per min. With its Call-in option, at about $3 per month, user gets a phone number in over 50 US/UK cities that goes (roams) with him and lets people call him at local rates. Other features like file exchange, chat history, voicemail with customisable messages, Instant messaging (IM), conference calling and call recording are pretty useful too.

Except the chargeable Call-In add-on, the free Access Numbers (unfortunately they're all US/CA numbers) enable the user to receive call to his Gizmo account from the traditional phone system.

Unlike Skype, it always assigns a SIP number (looks like 1-747-XXX-XXXX) with your Gizmo identifier so you can make calls to and receive calls from over 100 VoIP networks all over the world, for free.

GizmoProject introduced 4.0 beta with video calling and a new look in Dec. Except free video calls, it allows Meta-IM to chat with AIM, Yahoo, Windows Live, GTalk, iChat and more. Chat logging and tabbing are also of interesting features.

Gizmo project is also available on Nokia & Treo handheld, called GizmoVoIP. It saves money making Internet calls with the WiFi phone. The GizmoVoIP plug-in is tested with N80, N96, E61i & E65. A special version for N800 is available.

Gizmo5 beta is recently released to generic mobile phone users. Note that calls are charged differently than with Gizmo project (it charges for the two legs of the call). For example, USD 3.8 cents per min. for calling China from Singapore, as compared to USD 1.8 cents with Gizmo project.
