Anton,
I understood from you that you are using 2 opensips instances - one as
proxy, another one as b2bua - is this correct ?
The script you posted here , which one is ?
maybe having a sip capture of the call will help a bit (taken from both
opensips)
Regards,
Bogdan

Hi, Bogdan.
Please take a look - it is very small openSIPS cfg that cause described
situation.
When callee ends a call with this cfg a '404' is sending from line marked #
Here
It seems that BYE request is processing twice - one time in B2B (with to-tag
and 'route' header), second time in openSIPS (with to-tag but 'route'
header).
What I missed in the config?
route
{
xlog("*** route -> M=$rm R-URI=$ru F=$fu T=$tu SRC=[$si:$sp]
ID=$ci\n");
if (has_totag())
{
if (loose_route())
{
if (is_method("INVITE"))
record_route();
route(1);
}
else
{
if (is_method("ACK"))
{
if (t_check_trans())
t_relay();
exit;
};
sl_send_reply("404", "Not here"); # Here
};
exit;
}
if (loose_route())
{
xlog("L_ERR", "*** [ROUTE] : Attempt to route with preloaded
Routes [$fu/$tu/$ru/$ci]\n");
if (!is_method("ACK"))
sl_send_reply("403", "Preload Route denied");
exit;
};
if (!is_method("REGISTER|MESSAGE"))
record_route();
alias_db_lookup("dbaliases");
if (is_method("INVITE"))
{
if (src_ip != myself)
{
b2b_init_request("top hiding");
exit;
};
if (!dp_translate("0", "$ru/$ru"))
{
sl_send_reply("405", "Error DP");
exit;
};
if (!lookup("location", "m"))
{
sl_send_reply("405", "Error");
exit;
};
route(1);
exit;
};
if (is_method("REGISTER"))
{
if (!save("location"))
sl_reply_error();
exit;
};
}
route[1]
{
if (!t_relay())
{
sl_reply_error();
exit;
};
}

Bogdan, you are right!
I sent 404 from script because of BYE, that was sent from B2B to
openSIPS is
has_totag() but not loose_route()

Hi Anton,
it seams that your opensips proxy generates the 404 - replies are not
by
default sent, so it must have been sent from script. I suspect your
sequential requests are not properly handled and it hits the
lookup(location) (which is for initial requests).

Bogdan

Hi Bogdan.
I fixed the B2B loop, but openSIPS still replies 404.

And, openSIPS replies to B2B '404'
I see 2 potential moments:
1) I'm changing 'From' field on stage 2.
2) On stage 3 a field 'Contact' is "Contact:
<sip:192.168.0.10:5060;transport=udp>" althought I defined
"modparam("b2b_logic", "server_address", "sip:[email protected]")"

Hi Anton,
The ERROR line you have here are not essential - they simply say
that
the warning (optional) hdr was not added. Not an actual error.
Can you check doing a capture at net level who is generating the
404
reply? from opensips script, for final callee ?

Bogdan
