<p>Hi,<br>
the rr header for loopback is added by sipwise... and
I don't think that it's a problem.<br>
I tested the same scenario without topos and with same
sip flow it's all ok.<br>
Anyway, I created a simple scenario without sipwise
and I have the same problem with topos.<br>
I think (but ask you) topos have a bug when receive a
request (in my case re-invite) into dialog with rr.<br>
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.<br>
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.<br>
<br>
New simple call flow:<br>

<b>The problem:</b><br>
the 200 ok of re-invite is corrupt by
topos, it hasn't via header and contact
isn't modified, then the uac can't send
the ack.<br>
<br>
In the kamailio trace I see the ERROR
below:<br>
<b>E!: U 22/09/2017 10:24:19:880 proxy0:
ERROR: topos [tps_storage.c:1254]:
tps_db_update_dialog(): no valid dlg
uuid</b><br>
<br>
<b>The questions are:</b><br>
Can I use topos for this scenario?<br>
Is it possible that topos have bug when
receive a re-invite with record-route
headers? Infact, in simple scenario
without record-route (call and hold
between tow subscriber) everything works!<br>
<br>
<b>My opinion is</b>: when topos receive a
request with record-route generates from
record-route the new aleg and bleg tags
(atpsh-xxxxx, btpsh-yyyyyy) but don't save
their in internal database if the request
is internal at dialog. Then a reintive
whit record-route headers, generate new
aleg/bleg tags but they aren't in
database, then the response 200 ok it
isn't elaborate.<br>

log and pcap trace.</p>
