<tt>Hi, Miha!<br>
<br>
It looks like loose_route() fails - did you try to look into the
logs and see if it indicates something? Is the SBC_1 IP
advertised in the Route header a listener of OpenSIPS?<br>
<br>
Also, if loose_route() fails, you should still try to match the
PRACK against the dialog. So your scripting logic should look
like this:<br>
<br>
if (has_totag()) {<br>
if (loose_route() || match_dialog()) {<br>
...<br>
}<br>
}<br>
<br>
Let us know how that goes.<br>
<br>
Best regards,<br>
</tt>

Why I am getting 404 from Opensips. is should be routed like seq request, right?
<font size="-1"> if (has_totag()) {
# sequential requests within a dialog should
# take the path determined by record-routing
if (loose_route()) {
xlog("loose_route");
#if ($DLG_status!=NULL)
xlog("dlg_status");
if (!validate_dialog()){
fix_route_dialog();
xlog("fix_route_dialog");
}
if (is_method("BYE")) {
setflag(1); # do accounting ...
#setflag(ACC_FAILED); # ... even if the transaction fails
} else if (is_method("INVITE")) {
# even if in most of the cases is useless, do RR for
# re-INVITEs alos, as some buggy clients do change route set
# during the dialog.
record_route();
xlog("check_fraud");
}
# route it out to whatever destination was set by loose_route()
# in $du (destination URI).
route(relay);
} else {
if ( is_method("ACK") ) {
if ( t_check_trans() ) {
# non loose-route, but stateful ACK; must be an ACK after
# a 487 or e.g. 404 from upstream server
t_relay();
exit;
} else {
# ACK without matching transaction ->
# ignore and discard
exit;
}
}
sl_send_reply("404","Not here");
}
exit;
