Hi,
the fix was done, thanks to Vlad, and included in the 1.8.2 release -
please update your 1.8 checkout and test again.

Hi Pierre-Yves,
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).
We will work on a patch as fast as possible (the fix was identified).

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