<div class=WordSection1>
<p class=MsoNormal>We are looking for an existing app that can be customized or
a developer that could create a fraud detection/prevention app from scratch.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Basically, we are looking for a way to automatically block
international calls that look to be “out of the norm”<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>The way we were thinking this would be done is to set a
threshold on how many INTL calls a number could make, if that threshold is
exceeded, INTL calls are blocked.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>The following points are what we had in mind<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoListParagraph style='text-indent:-.25in;mso-list:l0 level1 lfo1'><![if !supportLists]><span
style='mso-list:Ignore'>a)<span style='font:7.0pt "Times New Roman"'>
</span></span><![endif]>The app should be smart enough to recognize the usage
patterns of a number, and adjust the threshold for that number automatically.(
Example: if the threshold is set for 100 INTL calls a day, but the number
routinely makes 200 INTL calls a day, the app should adjust itself to whatever
the average is)<o:p></o:p></p>
<p class=MsoListParagraph style='text-indent:-.25in;mso-list:l0 level1 lfo1'><![if !supportLists]><span
style='mso-list:Ignore'>b)<span style='font:7.0pt "Times New Roman"'>
</span></span><![endif]>Should be able to enable/disable the INTL threshold on
a per number basis.<o:p></o:p></p>
<p class=MsoListParagraph style='text-indent:-.25in;mso-list:l0 level1 lfo1'><![if !supportLists]><span
style='mso-list:Ignore'>c)<span style='font:7.0pt "Times New Roman"'>
</span></span><![endif]>Should be able to easily disable or enable the block if
it accidentally blocks calls, or if it misses a block<o:p></o:p></p>
<p class=MsoListParagraph style='text-indent:-.25in;mso-list:l0 level1 lfo1'><![if !supportLists]><span
style='mso-list:Ignore'>d)<span style='font:7.0pt "Times New Roman"'>
</span></span><![endif]>Should have a hard set threshold for ALL calls. This
will not need to be automatically adjusted to usage patterns, but statically
set for each number, and can be removed if need be. (Example: by default all
numbers can only make 2000 calls a month, if they break 2000, calls NOT local
to that number gets blocked [I could help you determine if a call is local,
regional, or LD]. If we see that they are hitting this limit a lot, we want to
either be able to disable it, or change that threshold to a higher number.<o:p></o:p></p>
<p class=MsoListParagraph style='text-indent:-.25in;mso-list:l0 level1 lfo1'><![if !supportLists]><span
style='mso-list:Ignore'>e)<span style='font:7.0pt "Times New Roman"'>
</span></span><![endif]>Have a place for us to enter high risk countries, that
have their own threshold (we should be able to enable/disable this threshold on
a per number/per country basis, but does NOT have to figure out usage patterns)<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>We are open to other ideas. Here are the requirements for an
app built from scratch, or desired items for a pre-existing app<o:p></o:p></p>
