Re: [OpenSIPS-Users] Re-Invite routed to private IP

Tue, 03 May 2016 05:25:56 -0700 

Hi Julian,
The routing of the re-INVITEs is done based on the routing set learned during initial INVITE (routing set == far-end contact URI + all the Record-Routes). 


Check the original INVITE (on the callee side) and the 200 OK for it, to 
see if the routing set contains private (or wrong) IPs.

Hi John,

I investigated some traces from our old platform and I found a call
with a private VIA and the Re-Invite is done correctly.
You can find the trace here: http://siptrace.rolbox.net/ok.html

The trace with the broken Re-Invite here:

I don;t think so : force_rport just adds the port on which you 
receive to the first via header.

    We are using 2.1.2

    So we made a "huge" version update and also changed the kind of 
working

        What version do you use in your new install ?

             Hi Johan,


             we changed our platform 2 weeks ago from 1 OpenSips 
Proxy 1.6.4 to 3 OpenSips instances with topology hiding.
             Since we didn't have this problems earlier, I think it 
worked with the old platform.
             As we call force_rport() in the main_route, the private 
IP in the VIA header should be ignored, right?

             At the moment we call force_rport() in all our instances.

             I think, we should call force_rport() only on the edge 
server where we make the nat_handling, right?

                      Hi Johan,


                      as the asterisk is not administrated by us, I 
have to ask the customer.
                      As I understand you think the problem should be 
the private IP in the VIA header

                      and this should be fixed with STUN, right?

                               Hi guys,


                               we are using OpenSips 2.1.2 with 
topology_hiding.
                               Now we got trouble with Re-Invites, 
which are routed to the private IP from the "from".
                               The topology_hiding matches, but the 
Re-Invite is sent to the private IP from the "from".
                               Have we to call lookup again on the 
registrar/core, when we got a Re-Invite?
                               You can find the trace under 
http://siptrace.rolbox.net/siptrace.html


                               Kind regards,
