Hello,<br>
<br>
Looking in your SIP trace, I see that in the 200OK Contact, you have
Contact: <sip:72.XX.XX.140;did=7de.9accc6f5>. , and when
OpenSIPS is routing the ACK out, it is routing it to<br>
<br>
U 182.XX.XX.164:5060 -> 72.XX.XX.140:5060<br>
ACK sip:72.XX.XX.140;did=7de.9accc6f5 SIP/2.0.<br>
<br>
so not sure where exactly is the loop.<br>
<br>
Best Regards,<br>

<div>Hi,<br>
<br>
</div>
senario:<br>
<br>
</div>
[UA]-------------[Opensips]---------[Freeswitch]<br>
<br>
<br>
</div>
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>
<br>
</div>
How do i check whether Freeswitch using loose_route for
strict route? <br>
<div>
<div><br>
<div>
<div>
<div><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>
<br>
