Hello all of you, I hope I am writing to the right malling list :-) I have a trouble with SIPp and I am fighting with it to find a way to solve this problem.
In fact, I get a lot of errors like this: 2020-06-02 01:03:09.207362 1591052589.207362: Aborting call on unexpected message for Call-Id '71519-26112@192.168.20.1': while sending (index 8), received 'ACK sip:192.168.20.1:5072;transport=UDP SIP/2.0 >From my understanding, that appears when a ACK retransmission comes too late. In other words, 1st ACK is received by UAS as well as ReINVITE but a "late" retransmission of this 1st ACK comes while UAS is waiting for 100 trying. ----------> OPTIONS ----------> INVITE <---------- 100 <---------- 180 [ 500ms] Pause <---------- 200 ----------> ACK // UAC waits 500ms between ACK and ReINVITE ----------> INVITE (in dialog) <---------- 100 // a retransmission of previous ACK is received here [ 200ms] Pause <---------- 200 ----------> ACK ----------> BYE <---------- 200 <---------- 200 Therefore my question is : Is there a way to ignore such messages? Because this results in call failure whereas it's only the retransmission of a message already received, if SIPp ignore it the call flow could continue. I tried to add this parameter"-rtcheck loose" but it doesn't help me. Have any of you ever encountered this problem? Thank you very much for your help !
