Hi,
It may possible be that the received ACK is broken, leading to that kind
of looping. By broken I mean heaving wrong RURI or Route headers. Can
you post on a pastebin a sip capture of that call ?

Hi,
senario:
[UA]-------------[Opensips]---------[Freeswitch]
UA sending correct ACK to freeswitch but Opensips loose_route()
sending it to itself and it break dialog, If use fix_dialog_route()
then it works, I don't have any IP address added in domain table also.
How do i check whether Freeswitch using loose_route for strict route?
I have following script:
if (has_totag()) {
if (loose_route()) {
if (is_method("BYE")) {
#setflag(ACC_DO); # 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();
}
if (check_route_param("nat=yes"))
setflag(NAT);
# 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
xlog("non loose-route section\n");
#t_relay();
exit;
} else {
# ACK without matching
transaction ->
# ignore and discard
xlog("ACK without matching
transaction\n");
exit;
}
}
