IndabaVox is the name, and it essentially allows users to “call in” to music sessions to record from wherever they are. You can think of it as a sort of portable tape deck, except that you and anyone else with access to a session can listen to and edit the recording from the Web. For spur-of-the-moment riff making or song demos, this can certainly help sustain fleeting memories into long-lasting sounds.
Calls through IndabaVox occur via VoIP. In order to connect via an outside line, you have to establish a session and click the button on the right side of the session window labeled “Record by phone...” You’ll be shown a pop-up with a phone number and PIN. If you are unable to access your default session when you first call the number provided, pressing ‘3’ on your keypad will initiate a request for your entry of the seven digit PIN. Once you’ve done so, just start sending off your audio. It may take some time for Indaba to register a submission. (As of writing this review, I still await the upload of a track to my freshly-created account.)
