Hi Denis,
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.
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?

Yes, but not for store this time to anywhere.
I want to detect the time of the first fraud call, and if this time,
for example, between 19:00 and 09:00, make some actions.
Can i do it with Opensips?
Thank you.

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

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