I did as described in previous mail, but there is a problem: the UAS sipp
sends responses to different SUT instance than it has received request from.
Is there a way to change it?
I'm putting below INVITE and 180 captured by Wireshark, exported as text.
INVITE comes from 192.168.96.85:5062, but the response 180 goes to
192.168.96.86:5061. These addresses are two of my servers, but there is a
problem when response comes to different server than the one that sent the
request.
