[VoiceOps] Fraud Management

[Jim Dalton]

Hello Shaun,

 

TransNexus offers a fraud detection solution, NexOSS-FC, to complement your
Session Border Controller (SBC) and block fraudulent calls at the ingress
edge of your network.  NexOSS-FC is a SIP redirect server.  You configure
your SBC to route every call to NexOSS-FC.  If no fraud is detected,
NexOSS-FC returns a 404 and your SBC routes the call to the next destination
in its routing table.  If fraud is detected, NexOSS-FC returns a 603 and the
SBC blocks the call.  If you want to divert fraudulent calls, NexOSS-FC can
return a 300 redirect message with the destination to where the SBC should
divert the call. 

 

The SIP Analytics of NexOSS-FC is better fraud protection than conventional
CDR Analytics because it obtains the call information sooner and because SIP
INVITES have call details for fraud detection that are not available in Call
Detail Records.  The solution is simple and effective.  Please contact me
offline if you want to evaluate the software.  More information is available
at http://transnexus.com/products/nexoss-fc/

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
