Gizmo5 4.0.3 (v382) for Windows

An internet telephone. As simple as an instant messenger. Gizmo5 uses your internet connection (broadband or dial-up) to make calls to other computers. With the click of a mouse, you’re connected to friends, family, and colleagues anywhere on earth. It’s just that simple. You talk clearly. For as long as you want. For free. And with inexpensive add-ons like CallIn and CallOut, you can talk to any telephone–mobile or landline–on the planet. Any phone? Yes. Download Gizmo5, and suddenly it all clicks–some calls are better online.

Gizmo5 is the name of a peer-to-peer VoIP network and of a proprietary freeware soft phone for that network. Gizmo5 was founded by Michael Robertson. Unlike its competitor network Skype, the Gizmo5 network uses open standards for call management, the Session Initiation Protocol and Jabber. But it uses several proprietary codecs, and like Skype, the Gizmo5 client is proprietary/closed source software. The Gizmo5 is run by the company SIPphone.

Since the Gizmo5 is based on the Session Initiation Protocol (SIP), it can interoperate with other SIP-based networks directly, although some data will always be routed via central SIPphone-servers, making it less than ideal in these settings from a privacy and security perspective. This avoids the phone system and is thus free of charge. Gizmo also will use encryption (SRTP) for Gizmo to Gizmo calls and works well with Phil Zimmermann's new Zfone secure add on.

The Gizmo5 software also has features that Skype lacks (or offers at an additional fee), such as interoperability with other systems/services via the SIP standard, built-in recording, and free voicemail. Gizmo also allows paid members of LiveJournal to make 'voiceposts' if they are unable to use the voicepost telephone lines provided by the website.

Unlike many of its competitors, Gizmo supports outbound caller ID in the United States, where people commonly reject incoming calls from unknown numbers. Skype and most other VoIP services seem to lack this feature.

Gizmo5 also works on your mobile phone. IM, make cheap calls, and share files by installing Gizmo5 Mobile.
