I'm responding to this email[3] to the pjsip development list. Has RTP/RTCP over TCP already been developed for pjsip? I am working on a proof of concept showing audio can be passed over TCP between two Android Orbot clients running CSipSimple on a hidden service without a lot of latency. This is important for user privacy since it reduces or totally eliminates trap & trace[4]. In the real world "trap and trace" is the biggest privacy threat to almost all phone users because it is easiest to analyze. In addition, trap & trace may cause problems for purveyors of private communications since they are just one subpoena away from losing their credibility or even their business/freedom. Thanks!
