Hello,</div>
<div style="font-family: Calibri, Helvetica, sans-serif, serif, EmojiFont; font-size: 16px;">
<br>
</div>
<div style="font-family: Calibri, Helvetica, sans-serif, serif, EmojiFont; font-size: 16px;">
I have some questions about fraud detection module and more particulary about the sequential call statistics.</div>
<div style="font-family: Calibri, Helvetica, sans-serif, serif, EmojiFont; font-size: 16px;">
I am actualy in opensips version 2.2.2 but I tried in 2.2.4 and 2.2.7, and I don't understand well behavior what I see on each version.</div>
<div style="font-family: Calibri, Helvetica, sans-serif, serif, EmojiFont; font-size: 16px;">
<br>
</div>
<div style="font-family: Calibri, Helvetica, sans-serif, serif, EmojiFont; font-size: 16px;">
1) First, in relation to the behavior of the sequential call statistics, I will give you an exemple to try to explain what I expected and what I found.</div>
<div style="font-family: Calibri, Helvetica, sans-serif, serif, EmojiFont; font-size: 16px;">

</div>
<div style="font-family: Calibri, Helvetica, sans-serif, serif, EmojiFont; font-size: 16px;">
I have this following rules :</div>

</div>
<div style="font-family: Calibri, Helvetica, sans-serif, serif, EmojiFont; font-size: 16px;">
User 10000 call the 0033123456789, I do check_fraud(10000, 0033123456789, 10000), who match with the rule 1, the sequential call counter of the rule 1 goes from 0 to 1.</div>
<div style="font-family: Calibri, Helvetica, sans-serif, serif, EmojiFont; font-size: 16px;">
User 10000 call the 0033123456789, I do check_fraud(10000, 0033123456789, 10000), who match with the rule 1, the sequential call counter of the rule 1 goes from 1 to 2.</div>
<div style="font-family: Calibri, Helvetica, sans-serif, serif, EmojiFont; font-size: 16px;">
User 10000 call the 0044123456789, I do check_fraud(10000, 0044123456789, 10000), who match with the rule 2, the sequential call counter of the rule 2 goes from 0 to 1.</div>
<div style="font-family: Calibri, Helvetica, sans-serif, serif, EmojiFont; font-size: 16px;">
User 10000 call the 0033123456789, I do check_fraud(10000, 0033123456789, 10000), who match with the rule 1, the sequential call counter of the rule 1 goes from 2 to 3 --> I was expecting that the counter to go back to 1 cause the last number called by this
user is different.</div>
<div style="font-family: Calibri, Helvetica, sans-serif, serif, EmojiFont; font-size: 16px;">
User 10000 call the 0033987654321, I do check_fraud(10000, 0033987654321, 10000), who match with the rule 1, the sequential call counter of the rule 1 goes from 3 to 4 --> I was expecting that the counter to go back to 1 for the same reasons than the previously
case, and further, for this rule and prefix, le number called is different, that's why I was expecting even more that the counter to go back to 1</div>
<div style="font-family: Calibri, Helvetica, sans-serif, serif, EmojiFont; font-size: 16px;">
<br>
</div>
<div style="font-family: Calibri, Helvetica, sans-serif, serif, EmojiFont; font-size: 16px;">
User 20000 call the 0033123456789, I do check_fraud(20000, 0033123456789, 20000), who match with the rule 1, the sequential call counter of the rule 3 goes from 0 to 1.</div>
<div style="font-family: Calibri, Helvetica, sans-serif, serif, EmojiFont; font-size: 16px;">
User 20000 call the 0033123456789, I do check_fraud(20000, 0033123456789, 20000), who match with the rule 1, the sequential call counter of the rule 3 goes from 1 to 2.</div>
<div style="font-family: Calibri, Helvetica, sans-serif, serif, EmojiFont; font-size: 16px;">

</div>
<div style="font-family: Calibri, Helvetica, sans-serif, serif, EmojiFont; font-size: 16px;">
User 10000 call the 0033123456789, I do check_fraud(10000, 0033123456789, 10000), who match with the rule 1, the sequential call counter of the rule 1 goes from 4 to 5 --> For this user, this prefix, le called number is different than the previous one called,
I was expected that the counter to go back to 1 even if another user have called this number just previously.</div>
<div style="font-family: Calibri, Helvetica, sans-serif, serif, EmojiFont; font-size: 16px;">
<br>
</div>
<div style="font-family: Calibri, Helvetica, sans-serif, serif, EmojiFont; font-size: 16px;">
For summarize, I was expected that the counter is reset per user for all its rules, from the time the number called by the user is different from the previous one.</div>
<div style="font-family: Calibri, Helvetica, sans-serif, serif, EmojiFont; font-size: 16px;">
<br>
</div>
<div style="font-family: Calibri, Helvetica, sans-serif, serif, EmojiFont; font-size: 16px;">
2) Secondly, the FRAUD statistics are daily reset, but which parameter are concerned?</div>
<div style="font-family: Calibri, Helvetica, sans-serif, serif, EmojiFont; font-size: 16px;">
<span style="white-space: pre;"></span>Total calls</div>
<div style="font-family: Calibri, Helvetica, sans-serif, serif, EmojiFont; font-size: 16px;">
<span style="white-space: pre;"></span>Calls per minute</div>
<div style="font-family: Calibri, Helvetica, sans-serif, serif, EmojiFont; font-size: 16px;">
<span style="white-space: pre;"></span>Concurrent calls</div>
<div style="font-family: Calibri, Helvetica, sans-serif, serif, EmojiFont; font-size: 16px;">
<span style="white-space: pre;"></span>Number of sequential calls</div>
<div style="font-family: Calibri, Helvetica, sans-serif, serif, EmojiFont; font-size: 16px;">
<span style="white-space: pre;"></span>Call duration</div>
<div style="font-family: Calibri, Helvetica, sans-serif, serif, EmojiFont; font-size: 16px;">
<br>
</div>
<div style="font-family: Calibri, Helvetica, sans-serif, serif, EmojiFont; font-size: 16px;">
3) Thirdly and the last point, is it possible to set a value for a parameter rule who permit to don't check this one? Like set the warning and critical parameter values of the sequential call to -1 for a rule for exemple (I have find this supposition into the
mailing list).</div>
<div style="font-family: Calibri, Helvetica, sans-serif, serif, EmojiFont; font-size: 16px;">

</div>
<div style="font-family: Calibri, Helvetica, sans-serif, serif, EmojiFont; font-size: 16px;">
Thank you in advance for your answer,</div>
<div style="font-family: Calibri, Helvetica, sans-serif, serif, EmojiFont; font-size: 16px;">
