I ran autogen.sh, configure, make and make check again and now NTA check is ok. > I could not run the nua tests, I hope this patch does not break anything. :) I ran nua tests and the patch doesn't work. The following tests after applying the patch failed: check_session.c:1622:E:2.5 - Call with preconditions:call_2_5_1:0: (after this point) Test timeout expired check_session.c:1704:F:2.5 - Call with preconditions:call_2_5_2:0: Assertion 's2_check_callstate(nua_callstate_completing)' failed check_session.c:1781:E:2.5 - Call with preconditions:call_2_5_3:0: (after this point) Test timeout expired check_etsi.c:334:F:6.1 - ETSI CC OE - Call Establishment:SIP_CC_OE_CE_TI_011_012:0: Failure 's2_sip_check_request_timeout(SIP_METHOD_ACK, 3)' occured :( > > Thanks in advance, > > Paulo Pizarro > ------------------------------------------------------------------------------ Start uncovering the many advantages of virtual appliances and start using them to simplify application deployment and accelerate your shift to cloud computing. http://p.sf.net/sfu/novell-sfdev2dev _______________________________________________ Sofia-sip-devel mailing list Sofia-sip-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/sofia-sip-devel
