<DIV><FONT face=Arial size=2>Hi </FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I am a premium voice service provider giving some
services on IVR to a Telco X . As my premises is some 10 kms away from that
telco , i have taken a PRI connection (30 DID with 1 hunting/pilot number) from
telco Y . When a customer of Telco X dials my short code @Rs.6/- per
minute his call is forwarded on the PRI connection of telco Y . All this
works fine..</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Now the problem arises during billing , many
customers of Telco X / Telco Z / Telco Y somehow get to know the pilot number of
telco Y and they directly dial in (it becomes a local call and not a
premium rate) the rsult being i dont get paid for those minutes and am giving
the service free virtually ...I tried to solve the problem as follows
:</FONT></DIV>
<DIV> </DIV>
<DIV><FONT face=Arial size=2>1. If i filter the calls using DNIS - no
matter people call short code or my pilot number - the DNIS would always be
returned as the pilot number</FONT></DIV>
<DIV><FONT face=Arial size=2>2. If i filter calls using ANI so that i allow
</FONT> <FONT face=Arial size=2>only customer of Telco X , then eventhough
i minimise the damage - but still am not sure if that customer X has dialled
short code or long code ?</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>this question may sound off-topic but in asterisk
is there a way out ?</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Rgds</FONT></DIV>
