Hello, I have some questions about fraud detection module and more particulary about the sequential call statistics. 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.
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. I have this following rules : ruleid profileid prefix ... 1 10000 0033 2 10000 0044 3 20000 0033 4 20000 0044 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. 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. 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. 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. 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 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. 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. 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. 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. 2) Secondly, the FRAUD statistics are daily reset, but which parameter are concerned? Total calls Calls per minute Concurrent calls Number of sequential calls Call duration 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). Thank you in advance for your answer, Best regards, Benjamin
