Hi, The pjsip in UAS mode, receives a call and answers it. The ACK is lost on wire, pjsip keeps on trying with 200 ok which is fine. Now pjsip receives a BYE. pjsip tears down call, but still keeps on retrying with 200. Further debugging revealed it has torn down BYE transaction but INVITE transaction is ON 2014-06-14 10:16:14.945 dlg0x4a07378 ..Transaction tsx0x4a0f328 state changed to Terminated 2014-06-14 10:16:14.945 tsx0x4a0f328 Timeout timer event 2014-06-14 10:16:14.945 tsx0x4a0f328 .State changed from Terminated to Destroyed, event=TIMER 2014-06-14 10:16:14.945 tdta0x4a2ba10 ..Destroying txdata Response msg 200/BYE/cseq=2 (tdta0x4a2ba10) 2014-06-14 10:16:14.945 tsx0x4a0f328 Transaction destroyed! 2014-06-14 10:16:17.447 tsx0x4a106f8 Retransmit timer event 2014-06-14 10:16:17.447 tsx0x4a106f8 .Retransmiting Response msg 200/INVITE/cseq=1 (tdta0x4a1cf60), count=3, restart?=1 2014-06-14 10:16:17.447 pjsua_core.c .TX 755 bytes Response msg 200/INVITE/cseq=1 (tdta0x4a1cf60) to TCP 10.221.108.102:49295 Regards, rajesh -------------- next part -------------- An HTML attachment was scrubbed...
