<p><tt>Hi Denis,<br>
</tt></p>
<p><tt>The fraud detection module has no such mechanism, currently.
We could invent some variables such as $frd_last_warn, $</tt><tt><tt>frd_last_crit,
$frd_first_warn, $frd_first_crit. They would output a UNIX
timestamp. If there were no warnings during the current
interval, the timestamp value would be 0. Can't think of
anything better now - you can polish this idea and open up a
pull request if you want.<br>
</tt></tt></p>
<p><tt>How many users do you have? The "cachedb_local" offers a fast
and configurable hash implementation. Why wouldn't it be a good
solution in order to store/fetch the above-mentioned timestamps
for each of your users?</tt></p>
<p><tt>Best regards,</tt><br>

<div>Yes, but not for store this time to anywhere.</div>
<div>I want to detect the time of the first fraud call, and if

<div>Can i do it with Opensips?</div>

<p>Hi Denis,<br>
<br>
Yes, the "sequential calls" holds the size of the last batch
of calls<br>
sent to the same number. For example, if a user were to dial
44 and 45<br>
prefixes in a round-robin manner, his "sequential calls" value
would<br>
never exceed 1.<br>
<br>
So you want to check the time of the last fraud detection
attempt for a<br>
user? You can use "cachedb_local", for example, and hold the
last fraud<br>
detection timestamp for each user. Also, note that
check_fraud() [1] has<br>
some useful return codes (-1 and -2), in case you don't want
to use the<br>
E_FRD_ events.<br>
<br>
Cheers,<br>

<blockquote> Hello, Liviu!<br>
Thank you very much!<br>
I will try your fix.<br>
And, What does "Sequential calls" mean? These are calls to
one number?<br>
So, if we have situation dealing with reset counters, i want
to make<br>
one thing.<br>
I want to check the time when fraud has been detected and if
this<br>
time, say, after 19:00 make some actions. How can i check
time of the<br>
call processing?<br>
Thank you.</blockquote>
