High-level Java API for easily creating SIP enabled VoIP applications. Suitable for either a desktop (softphone, phone applet, incoming call screener) or server-side (auto attendant, ACD, voicemail) application. Defines a generic media provider interface, and includes an implementation of that interface which uses the Java Media Framework. Flibble-VoIP is the underlying engine of the VoxCenter softphone

NEWS 6/11/2008 - Flibble-VoIP Beta 2 has been released. In addition to the addition of the roadmap items below, many fixes were made to STUN, SIP Signaling, media, DTMF, and authentication. Tested with Vonage, VoIP.com, Broad Voice, and IdeaSIP.

News - 5/26/2007: I've modified the way flibble-voip is being packaged. This should be less confusing now, and all of the source and binary packages are available (on sourceforge). Fixed an issue with authentication challenges on outgoing calls. This means the PlaceCall example, with two way audio, is functional with VoIP providers, such as Vonage.

News - 5/5/2007: Tested with a Vonage softphone account. Can receive calls, verified two way audio!
