<tt>Hi Pierre-Yves,<br>
<br>
Thanks for the detailed report - indeed, it seems to be a problem
with the dialog matching (for sequential request) when having
topology hiding in combination with spiraling (as your call goes
twice through opensips with topo hiding).<br>
We will work on a patch as fast as possible (the fix was
identified).<br>
<br>
Regards,<br>

<br>
I'm facing an issue of ACK Looping using opensips.<br>
<br>
the configuration is the following : <br>
- Opensips v1.8.1 (same problem with 1.7.2).<br>
- using dialog "topology hidding" feature.<br>
- using 2 @IPs (one to reach customers, one to reach SIP
Platform) (mhomed=yes)<br>
<br>
<br>
Customer1/2 <--->Opensips (topology hidding) <---->
SIP Platform<br>
<br>
The call flow is the following: Customer1 call Customer2, both are
connected on the same Opensips <br>
(when Customer1 and Customer2 are located on different opensips,
no problems)<br>
Customer1 <-->opensips <--->SIP Platform
<-->opensips <-->Customer2 <br>
<br>
<br>
INVITE/180/200 sequence is working well.<br>
<br>
But the ACK of the 200 OK is looping between Customer2
-->Opensips -->SIP Plateform --><b>Opensips -->SIP
Platform--->Opensips</b>... instead of doing directly <br>
Customer2--->Opensips --->SIP Plateform -->Opensips
-->Customer1<br>
<br>
<br>
Attached, a network capture taken on opensips server.<br>
<br>
<br>
I had a look at "dlg_list", 2 dialogs are created for this call.
Might be a problem with did matching ? I tested with <br>
modparam("dialog", "dlg_match_mode", 0) and<br>
modparam("dialog", "dlg_match_mode", 2)<br>
<br>
<br>
Could someone help me fixing the issue ? Do you have some hints of
the root cause of issue ?<br>
<br>
<br>
Regards,<br>
Pierre-Yves<br>
