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
