<p><font size="-1">Hi,</font></p>
<p><font size="-1">I have been using the (modules 2-2) Fraud
Detection Module for over a year now and everything has seemed
OK, but an incorrectly set up auto dialler has uncovered an
issue with concurrent calls...</font></p>
<p><font size="-1">Normally you make a call and the concurrent calls
statistic increments for the user, once the call is cleared down
the concurrent calls statistic decrements, so far so good.</font></p>
<p><font size="-1">If you make a call to a non-existent number and
the gateway returns 404 not found, the concurrent calls
statistic increments but does not decrement. The same is true
if you call a valid number but cancel the call before the callee
answers.</font></p>
<p><font size="-1">So I can get the situation where MI command
show_fraud_stats shows:<br>
</font> </p>
<p><font size="-1">calls per minute:: 1<br>
total calls:: 28<br>
concurrent calls:: 24<br>
sequential calls:: 2</font></p>
<p><font size="-1">But there are no active dialogs on the system. I
make the call to the check_fraud function during the initial
invite code before t_relay to the gateway.</font></p>
<p><font size="-1">Any feedback would be appreciated.<br>
