Gizmo5 is one in a long line of VoIP applications that allows you to use your internet connection to make cheap phone calls.

If you're a Google Talk fan, like me, then the first good thing is that Gizmo5 and Google Talk are now connected. This means that Gizmo5 users can now send instant messages to Google Talk users but unfortunately, you can't call them although the developers promise that it's coming soon. To send Instant Messages, simply click on the IM icon next to your contacts name and you can instantly text other Gizmo5 users. One great feature of Gizmo5 is that you can perform free mobile phone and landline conference calling although you have to setup the system beforehand with the Gizmo5 FreeConferenceCall utility which can be tricky due to a few complicated configuration options. Another interesting feature is that Gizmo5 includes Asterisk PBX Support which means that you can now log into your virtual office with Asterisk PBX software. This basically means that you can receive calls and access your Gizmo5 phone wherever you are in the world. I also like the fact that it includes a free recorder which is something lacking in Skype.

Easy to use and integration with GTalk makes this a nice little app although it's calling rates need to be a lot more competitive before it can compete with Skype.
