Re: [VoiceOps] Fraud Management

Hi Shaun,

most systems work off CDR files (or Radius or Diameter steams) so are proprietary in what products they support (http://oculeus.com is one such system).  There are some products that are auto-learning based on SIP monitoring so are device independent.  http://tollshield.com is one of them and builds a network profile over several week to understand "normal" traffic patterns.  It can alert on variations of those patterns.  These systems requires monitoring ports whereas the CDR approach does not need SPAN ports.

Also there is a difference between systems that can alert on fraud on ones that can proactively shut off service to suspect devices.  The proactive ones are usually device specific and more expensive and raise the risk of false positives.

Hi Brad,

Neither - We are not using a product at this stage; using a combination of routing profiles (BSFT) and originating source IPs to block suspect traffic.

Shaun,

Have you used the SIP or CDR based product?

Hi Guys,

 

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.

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.

Subsequently we are looking for alternatives.

 

Regards,

Shaun
