Please look packets #3010 and #4867
Then look ticket #1215
<https://github.com/kamailio/kamailio/issues/1215> and Daniel comments
By RFC, the R-URI in ACK (and the other requests within dialog) has
to be the URI from the Contact of 200ok. But there is the address of
kamailio, making everything look like a strict routing and actually
breaking the sip routing.
According PCAP file kamailio froward reINVITE as strict router.
Think need to revert back R-URI header.

Hi,
the rr header for loopback is added by sipwise... and I don't
think that it's a problem.
I tested the same scenario without topos and with same sip flow
it's all ok.
Anyway, I created a simple scenario without sipwise and I have
the same problem with topos.
I think (but ask you) topos have a bug when receive a request
(in my case re-invite) into dialog with rr.
It seems that wen topos receive a request into dialog with rr it
generate a new aLeg tag different about aLeg tag of initial dialog.
When topos receive the response it can't match the leg tags and
then send corrupt response, in my case a 200 Ok without via header.
New simple call flow:
