LogiSense’s International Fraud reporting is designed to detect abnormal amounts of calls made from BroadWorks or Sansay switches to international locations. Only outbound international calls are analyzed to scan for issues and report them via e-mail to pre-defined users. Data is stored in a manner such that future reporting criteria (changes to existing reports or new reports) should be easily added.
Real-Time Fraud Services
There are windows services that need to be running in order to perform real-time fraud processing.
...
FraudServiceUrl – URL to the listening Fraud [doman:8378/owner name/] e.g. http://localhost:8378/Logisense Corporation/
Candidate CDR Records
CDRs that are considered (by the BroadWorks/Sansay rating code) for international fraud detection are records which:
...
(Note: field numbers above are based on BroadWorks/Sansay CDR fields starting with 1, not 0-based)
InternationalOutboundCallLog Table
After the previous lookups have occurred, the data is then stored in the InternationalOutboundCallLog table. The table is represented in SQL Server as the following:
...
Country - a list of International countries detailing if they are in the restricted list or not
Country code - this table links countries from the Country table to their country codes to determine the called country
SansayFraudTerminationPrefixesToStrip - provides the possibility to strip the prefixes in this table from the called number
Anti-Fraud Reports
The anti-fraud reports themselves exist as stored procedures in SQL Server. They are scheduled by the SQL Server Agent as jobs and can be configured to run at whatever interval is desired. The stored procedures are also responsible for sending email notifications out, thus SMTP email must be configured in SQL Server (for information on that, please consult SQL Server documentation).
...
Information on reported activity is saved in the "FraudByCallAmountsHistory" and "FraudByCallAmountsOwnerHistory" tables for User and Owner reporting. These tables contain the EngageIP User/Owner Name, ID of the Last International Outbound CallLog Reported and Reported Time.

User from previous scenario makes $29 worth of international calls two hours later | No | None |
User from previous scenario then makes another $1.50 in international calls within the same hour as previous calls | Yes | Report is sent with the calls that totaled $29 and the most recent $1.50 in calls |
User makes $40 worth of international calls within an hour, but has a “Fraud Threshold” set on the user of 50 | No | None |
Same user as previous scenario makes $51 worth of calls within the hour | Yes | Report is sent with the $51 worth of calls |
Owner Report Examples
Scenario | Fraud Is Detected | Resulting Report |
There are no international calls within an owner | No | None |
Owners’ users have made $5 in the past hour of imported calls | No | None |
Owners’ users have made $500 of international calls in prior days/weeks | No | None |
Owners’ users (one or many) make $100.01 of international calls in the past hour of imported calls | Yes | Report is sent with the offending calls |
Any user within the owner from previous scenario makes another $1 worth of more international calls within the same hour | Yes | Report is sent with the new calls only. The user making the calls can be different than the user(s) making the previous calls |
User from previous scenario makes $99 worth of international calls two hours later | No | None |
User from previous scenario then makes another $1.50 in international calls within the same hour as previous calls | Yes | Report is sent with the calls that totaled $99 and the most recent $1.50 in calls |
Two users make $99 worth of international calls each (within the same hour), within different owners | No | None |
Reported Fields
The following fields are included in the emailed reports by default:
OriginatingIdentifier, TerminatingIdentifier, BillingIdentifier, StartTime, ReleaseTime, AnswerTime, Amount, Country, Owner, User, OriginalCDRID, RedirectingReason, Classification.
Reporting Recipients
The recipients of the reports are stored within the reports’ SQL stored procedures. To modify them, the value assigned to parameter ‘@recipients ‘ (passed into msdb.dbo.sp_send_dbmail) needs to be modified. If you plan on regularly changing the reports’ recipients, it’s advisable to use an email alias, which can be maintained on the email server.
