<p>Hi Denis,</p>
<p>The fraud detection module has no such mechanism,
currently. We could invent some variables such as
$frd_last_warn, $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.</p>
<p>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?</p>
<p>Best regards,</p>

<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>

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>
