<div dir="ltr"><div><div>OK, finally back at office after holidays.<br><br></div>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?<br><br></div>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.<br><div><div><br></div><div>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.<br><br></div><div>Thank you.<br></div><div><br><br></div></div></div><div class="gmail_extra"><br><div class="gmail_quote">On Tue, Dec 30, 2014 at 2:56 AM, Muhammad Shahzad <span dir="ltr"><<a href="mailto:shaheryarkh@gmail.com" target="_blank">shaheryarkh@gmail.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr"><div>OK, i will run some tests and get back to you.<br><br></div>Thank you.<br></div><div class="HOEnZb"><div class="h5"><div class="gmail_extra"><br><div class="gmail_quote">On Sat, Dec 27, 2014 at 10:22 PM, Daniel-Constantin Mierla <span dir="ltr"><<a href="mailto:miconda@gmail.com" target="_blank">miconda@gmail.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">

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.<br>
<br>
Can you run with debug=3 and see all the log messages, maybe you get
a further hint from there.<br>
<br>
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...<br>

<div>OK, i will upgrade my staging
server and do some testing.<br>
<br>
</div>
The acc module does not post
records anywhere, neither syslog
nor db. The problem is happening
to all calls (not any specific
call).<br>
<br>
</div>
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.<br>
<br>
</div>
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.<br>

<div bgcolor="#FFFFFF" text="#000000"> Hello,<br>
<br>
you can try with latest git
branch 4.2 and see the
results.<br>
<br>
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.<br>
<br>
Do you get the acc record in
syslog for INVITE?<br>
<br>
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.<br>
<br>
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.<br>
<br>
Cheers,<br>
Daniel

<div>Hi,<br>

<div>About 3 weeks

i am getting a lot

only BYE records
in acc table, no

<div>2. In kamailio
logs when ACK is

200 OK response
for INVITE, i see
