OK, i will upgrade my staging server and do some
testing.
The acc module does not post records anywhere, neither syslog nor db. The
problem is happening to all calls (not any specific call).
Regarding the FROM header, the only change done is to add "+" to callerid
(after replacing 00 if present), this is extensively tested feature in past
6 months.
I have analyzed all the SIP packets in call using ngrep, they all seem
perfectly fine. All packets (request + reply) are correctly received and
forwarded by kamailio. Unfortunately i deleted them and need to get new
trace. I will send it to you in the afternoon.
Thank you.

Hello,
you can try with latest git branch 4.2 and see the results.
At a quick look between the version you reported to work and the new
version you run, I couldn't spot a commit that could be the reason.
Do you get the acc record in syslog for INVITE?
How do you set the values for replacing From header? If you load from
database, be sure the values are valid. I see the uac module complains
about restoring operation. It might be the reason for the issues -- config
could be ok, but the subscriber data wrong.
You should save the traffic for a while and check the packets for
missing records -- you can use tools such as tcpdump, sipgrep, ngrep to
store the traffic in a file for later analysis. When you find a missing
record, search in the file with the sip traffic and see if something is
broken there.
Cheers,
Daniel

Hi,
About 3 weeks ago i upgraded one of my production server with latest
stable kamailio version 4.2.1-fad00a. Now i am getting a lot of complaints
about missing CDR events in ACC table. I observe following problems,
1. There are only BYE records in acc table, no record for INVITE or
ACK.
2. In kamailio logs when ACK is received against 200 OK response for
INVITE, i see following errors,
--
ERROR: <core> [parser/parse_from.c:113]: parse_from_uri(): failed to
parse From uri
ERROR: pv [pv_core.c:434]: pv_get_xto_attr(): cannot parse From URI
NOTICE: <script>: [udp:<null>@1.0.0.127:5060]: Call from '
you(a)kamailio.org' to 'you(a)kamailio.org' has been hanged up by

--
Of course all these errors are bogus, I have checked all headers in
ACK (not just FROM header), they all seem perfectly fine and valid.
3. Then the dialog times out,
--
WARNING: dialog [dlg_handlers.c:1440]: dlg_ontimeout(): timeout for dlg
with CallID '6D8BD23CAC65AE3C1DE1D0B531F87B8CFEAA9CB9' and tags

'7f55e81e0630-100007f-13c4-6009-2440a4-5fa31570-2440a4'
--
4. Any further sequential requests complain about "unable to find
dialog", e.g.
--
NOTICE: <script>: Sequencial 'BYE' request received from caller
ERROR: uac [replace.c:591]: restore_uri(): new URI [] shorter than old
URI [sip:00xxxxxxxxxx@sip.domain.com]
WARNING: dialog [dlg_handlers.c:1174]: dlg_onroute(): unable to find
dialog for BYE with route param '5ae1.d595' [7845:22877]
--
5. However the acc record for BYE is written to db and log file,
--
NOTICE: acc [acc.c:318]: acc_log_request(): ACC: transaction answered:

The same config was working fine with older version 4.2.0-97cab8. The
kamailio config i am using is pretty much standard,

}

Any ideas why its happening? Since it is 3 weeks old so may be problem
has already been spotted and fixed by someone else. Otherwise let me know
how can i provide more info to help fix this issue.
Thank you.
