Hello, we are integrating pjsip library in a voip project but we have a weird problem and we cannot figure out what is going on. We have two clients (java and python) and some times once python has sent an invite to start a call, java client raise the error shown below. java.lang.Exception: Title: pjsua_call_answer2(id, param.p_opt, prm.statusCode, param.p_reason, param.p_msg_data) W/System.err? Code: 171140 W/System.err? Description: INVITE session already terminated (PJSIP_ESESSIONTERMINATED) W/System.err? Location: ../src/pjsua2/call.cpp:493 It seems occurring randomly since sometimes it's going well, and sometimes it fails. We'd appreciate if someone could give us a hand. Thanks in advance, Pau. -------------- next part -------------- An HTML attachment was scrubbed...
