Hello,<br>
<br>
it should be safe, the prack doesn't change the state of the dialog
after it is established (state 4). If you see some side effects,
report them here.<br>
<br>
Perhaps the log message should be adjusted a bit. What version are
you using (kamailio -V)?<br>
<br>
Cheers,<br>
Daniel<br>

<p>Hello There,</p>
<p>We are detecting errors quite often on our kamailio servers
log:</p>
<p><br>
/usr/local/sbin/kamailio[17527]: CRITICAL: dialog
[dlg_hash.c:782]: bogus event 5 in state 4 for dlg 0<br>
x7fe0269a8be0 [1004:10921] with clid <a
moz-do-not-send="true"
href="mailto:%27034e8c8f-07daa8c0-001b56a3@192.168.210.2%27">'034e8c8f-07daa8c0-001b56a3@192.168.210.2'</a>
and tags '07daa8c0-33aeaec-t-1' '9304808465080725853<br>
'</p>
<p>After analyzing the issue We found that the root cause for
those errors is when kamailio gets PRACK message after 200 OK
(CSeq INVITE) in the same CALLID.<br>
To mention that those calls are successfuly established.<br>
This is due a complecated voice network.</p>
<p>As for today we are getting around 100 errors per kamailio
server every day. The number will increase to around 1000
errors per day in the near future. </p>
<p>Two questions please:</p>
<p>1. Can Kamailio safety deal with those errors with no service
effect <br>
2. Is there a way to decrease the level of those errors from
CRITICAL to INFO? As for today we are working in debug level 0
so no INFO written is written to the log in general.</p>
<p>I will appriciate for any assistant on this topic please.</p>
<p>Thanks,<br>
Arik. <br>
