<tt>Hi Guillaume,<br>
<br>
You need to keep in mind that the fix_nated_contact() should be
done (usually) for replies coming from users (potentially behind a
NAT). You should not do it for traffic coming from other SIP
servers.<br>
<br>

Hi Bogdan,<br>
<br>
Thank you for your answer.<br>
You were right, our SBC was sending us a broken BYE.<br>
<br>
Thank you for your enlightenment, it really save me this time.<br>

<tt>Hi Guillaume,<br>
<br>
The incoming BYE is broken - the IP of your OpenSIPS can be
found both in RURI and in the top Route header. As the IP is
found in RURI makes OpenSIPS think that the previous hop was a
strict router. and this leads to the infinite loop.<br>
<br>
Looking at it, I see the typical mistake of doing a
fix_nated_contact() and overwriting the original contact URI
in the 200 OK for INVITE (this contact is used as part of the
routing set for routing back sequential requests like BYE)<br>

Hello all,<br>
<br>
I'm working a project with multiples opensips (each handling a
particular role).<br>
So when an invite goes in our plateform, it crosse multiples
openips and can even sometime go though a specific opensips
multiples times.<br>
My problem is: When the called send a BYE I have a strange
behavior. One of my opensips which receive the BYE resend it
to itself and suppress the wrong route (last route instead of
the first route...).<br>
<br>
- For example this is the BYE message my opensips receive :<br>

172.99.37.52:5061) ):<br>

I know that my first header route is the same than my last
header route, and maybe this is why I have this beavior, but
this seems really odd to me.<br>
