<div>Hi Guys,</div>
<div><br>
</div>
<div>Trying to get a feel for what fraud systems are out there for VoIP service providers; primarily using terrestrial mediums (such as metroE; diginet) with clients interconnecting via IP PBXs, voice gateways and IP phones.</div>
</div>
</div>
<div>We have had fraud to international premium destinations which we are restricting based on calling profiles and originating source IPs; but neither is truly scalable.</div>
<div>Subsequently we are looking for alternatives.</div>
<div><br>
</div>
<div>Regards,</div>
<div>Shaun</div>
