We offer an open library to support serverless VOIP phonecalls for Instant Messengers.

Currently we work to implement Tstone into our partnerprojects, which are Retroshare.sf.net Serverless Instant Messenger and (serverbased) Multimessenger SIM-IM.org

Other projects are appreciated to use as well our openphoning Tstone libraries with components of OpenH.323 and OpenSIP written in C++ and with QT4 gui.

T stone is NOT endorsed by or affiliated with SKYPE. We are opensource and serverless.
