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:

Hi,
I'm trying to use topos module but I have a problem
with record-route header in re-invite for on hold.
Uac is a subscriber of sipwise platfrom (vm open
source version);
my kamailio version is:
/# kamailio -v//
//version: kamailio 5.1.0-dev7 (ppc/linux) //
//flags: STATS: Off, USE_TCP, USE_TLS, USE_SCTP,
TLS_HOOKS, DISABLE_NAGLE, USE_MCAST, DNS_IP_HACK,
SHM_MEM, SHM_MMAP, PKG_MALLOC, Q_MALLOC, F_MALLOC,
TLSF_MALLOC, DBG_SR_MEMORY, USE_FUTEX,
FAST_LOCK-ADAPTIVE_WAIT, USE_DNS_CACHE,
USE_DNS_FAILOVER, USE_NAPTR, USE_DST_BLACKLIST,
HAVE_RESOLV_RES//
//ADAPTIVE_WAIT_LOOPS=1024, MAX_RECV_BUFFER_SIZE
262144, MAX_LISTEN 16, MAX_URI_SIZE 1024, BUF_SIZE
65535, DEFAULT PKG_SIZE 8MB/
and uas is a subscriber of kamailio.
The call flow is:
UAC Sipwise Kamailio UAS
| | (topos active)
|
|-------- Invite -------->|---------- (1)Invite
----->|------- (2)Invite ----->|
|<------- 180/200 ------|<--- (4)180/(4)200
----|<------- 180/200 ------|
|---------- Ack --------->|----------- (5)Ack
------>|-------- (6)Ack ------->|
|--- Invite (hold) ----->|-- (7)ReInvite(hold)-->|--
(8)Invite (hold)--->|
|<--------- 200 ----------|<--------- (9)200
-------|<--------- 200 ----------|
| corrupt | corrupt |
|
|---- No Ack Sent-------|---- No Ack Sent-------|----
No Ack Sent-------|
*The problem:*
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.
In the kamailio trace I see the ERROR below:
*E!: U 22/09/2017 10:24:19:880 proxy0: ERROR: topos
[tps_storage.c:1254]: tps_db_update_dialog(): no valid
dlg uuid*
*The questions are:*
Can I use topos for this scenario?
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!
*My opinion is*: 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.
below messages details, attached kamailio log and pcap
trace.
tanks in advance for support,
Giuseppe*
