Thank you Bogdan for replying,
UAC send the ACK to the correct port of opensips but after it reaches
opensips, opensips doesn't know where to send this ACK
I tried to perform record routing in my cfg as in the performance test
tutorial( http://www.opensips.org/Resources/StressTests#toc6 test_E.cfg )
the same problem happend, ACKs is never forwarded
I traced the packages exchanged using wireshark & I found out that ACK is
looping inside opensips
here is the wireshark trace of only one call
http://opensips-open-sip-server.1449251.n2.nabble.com/file/n7134497/_221-6320%40192.168.1.69-Trace
_221-6320%40192.168.1.69-Trace
Attached the trace of wireshark
Note that port numbers were given as follow:
UAC:5069
opensips: 5060
UAS: 5066
& all resides in the same machine (192.168.1.69)
here is my config file:
