Kamailio itself doesn't alter CSeq method, unless you do something in
the configuration file.
Looking at the traces, the broken CSeq comes like that to Kamailio --
first part here indicates that 192.168.0.1:5060 is Kamailio, and next
shows the packet sent by .0.33 to .0.1 (kamailio):
U 2015/06/22 17:08:52.730652 192.168.0.1:5060 -> 192.168.0.3:6060
SIP/2.0 100 trying -- your call is important to us
...
U 2015/06/22 17:08:52.735438 192.168.0.33:5060 -> 192.168.0.1:5060

So, if I got it right that .0.1 is kamailio, then the problem is not in
kamailio at all.

Perhaps you have an ngrep of the sip traffic?

Book: SIP Routing With Kamailio - http://www.asipto.com
Hello,
my setup is a kamailio server as registrar and Blox as SBC.
Blox is a freeware GUI with Opensips as framework.
Kamailio is located in the private network and Blox operates with 2 NICs
(private and public)
Now the following problem:
If I make a call from public (phonerlite) to private (mayah), the
connection don't reach the "framed" state and is "broken" after
30 sec.
After evaluating the log files, I found that the CSeq from Kamailio is
wrong.
The invite comes from
CSeq: 9 INVITE
The reply is with CSeq 1

And here the information from the opensips log files:
Jun 22 14:30:32 localhost blox-0-9-6-beta[1975]:
ERROR:core:parse_cseq: no method found
Jun 22 14:30:32 localhost blox-0-9-6-beta[1975]: ERROR:core:parse_cseq:
bad cseq
Jun 22 14:30:32 localhost blox-0-9-6-beta[1975]:
ERROR:core:get_hdr_field: bad cseq
Perhaps someone of you knows this failure or can tell me how to solve
this problem?
Cheers,
Kai
