Finally we got Tapioca VoIP 0.2 released. This release has a lot of improvements compared to 0.1, such as multiple codecs support, a totally rewritten UI and a lot of other cool stuff. But a lot more needs to be done, and we intend to release new versions more frequently. Some features you can expect for the folowing releases are support for Proxy/Registrar, STUN support and Presence. The release notes and instructions on how to install it can be found here.
