<div class="moz-cite-prefix"><tt>Hi,<br>
<br>
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 ?<br>
<br>
Regards,<br>

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. <br>

How do i check whether Freeswitch using loose_route for strict
route? <br>

I have following script:<br>
<br>
if (has_totag()) {<br>
<br>
if (loose_route()) {<br>
<br>
if (is_method("BYE")) {<br>
#setflag(ACC_DO); # do
accounting ...<br>
#setflag(ACC_FAILED);
# ... even if the transaction fails<br>
} else if
(is_method("INVITE")) {<br>
# even if in most of
the cases is useless, do RR for<br>
# re-INVITEs alos, as
some buggy clients do change route set<br>
# during the dialog.<br>
record_route();<br>
}<br>
<br>
if
(check_route_param("nat=yes"))<br>
setflag(NAT);<br>
<br>
# route it out to whatever
destination was set by loose_route()<br>
# in $du (destination URI).<br>
route(relay);<br>
} else {<br>
<br>
if ( is_method("ACK") ) {<br>
if ( t_check_trans() )
{<br>
# non
loose-route, but stateful ACK; must be an ACK after<br>
# a 487 or
e.g. 404 from upstream server<br>
xlog("non
loose-route section\n");<br>
#t_relay();<br>
exit;<br>
} else {<br>
# ACK without
matching transaction -><br>
# ignore and
discard<br>
xlog("ACK
without matching transaction\n");<br>
exit;<br>
}<br>
}<br>
