The retrasnmitted meesages 200 OK are identicals.
I´m using SIPp with Asterisk.Asterisk show this errors:
Sep 12 18:52:36 WARNING [4620]: chan_sip.c:1835 retrans_pkt: Maximum
retries exceeded on transmission 778f89593967725f0abe40eb1752504c (at)
10.10.206.53 for seqno 1620 (Critical Response)
Sep 12 18:52:36 WARNING [4620]: chan_sip.c:1835 retrans_pkt: Hanging
up call 778f89593967725f0abe40eb1752504c (at) 10.10.206.53 no reply to
our critical packet.
