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:

<giuseppe.pandolfi(a)aethra.com <mailto:giuseppe.pandolfi@aethra.com>>:
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*
