Looking at debug level 3 kamailio logs and mysql query logs, there is no attempt to insert data in acc table at all except for BYE message.OK, finally back at office after holidays.I have done extensive testing of various kamailio revisions (backwards up to November) and it seems that problem is not related to any change in native code. It is somehow related to kamailio.cfg, which is very strange, since only changes in previous deployment and currently deployment of cfg file are related to dialog module (there are a lot of them, e.g. dialog timeout added, dialog profile setup, several dialog variables added and set, dialog start, end and failure event routes configured etc. etc.). However, there is no change related to acc setup and its configuration is still compatible with default kamailio.cfg. Does this make any sense to you?Today i will try to compare working cfg file (back from mid-November, which inserts all ACC event records) with current cfg file (which only inserts BYE event records) and see if i can find that configuration changes that are causing this behavior.Thank you.On Tue, Dec 30, 2014 at 2:56 AM, Muhammad Shahzad <shaheryarkh@gmail.com> wrote:OK, i will run some tests and get back to you.Thank you.On Sat, Dec 27, 2014 at 10:22 PM, Daniel-Constantin Mierla <miconda@gmail.com> wrote:I did a basic test (acc with parameters as in default kamailio.cfg) and invite is accounted ok. I used master branch, but there is no difference with acc from 4.2.
Can you run with debug=3 and see all the log messages, maybe you get a further hint from there.
Also, you can try with clone_msg parameter set to 0 - it is one of latest additions to acc module, just be sure you don't have some corner case situation...
Cheers,

Between these two log lines there is no log from acc module.
Thank you.

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.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.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).
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,

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@kamailio.org' to 'you@kamailio.org' has been hanged up by '<null>' at '1419364717.255484'
--
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 '1D3ECD34F5731AB845BA3064AC95BB2D' '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,
--

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.
