Outbound toll fraud occurs far more often than you might realize. From business customer employees who make a few unauthorized long-distance calls after hours to hackers who gain access to an outbound PBX dial tone, toll fraud can total thousands of dollars annually. A single instance of SIP hacking can quickly produce a bill in the tens of thousands for overseas toll fraud. Worldwide losses from toll fraud are estimated to be $35-40 million each year.
Clients with hosted PBX solutions (for your business customers) that are compromised, the costs for these fraudulent calls could hit your bottom line. Reconciling these instances are costly for everyone involved, involving researching the call and trying to collect.
The NAMS Fraud Traffic Controller (FTC) controls outbound toll fraud on your VoIP and TDM networks. By becoming an active element on your VoIP and TDM network, we can inspect each outbound call at its starting point. If those calls are determined to be fraudulent, the NAMS FTC releases those calls before it even leaves your network.
The NAMS FTC uses calling pattern thresholds based on NPA/NXX, NPA, Country Code/City Code, or Country code combinations to determine fraud. When preset hourly thresholds are exceeded, calls are disconnected or the system notifies you for further action. You may also set up blacklists, or whitelists, to handle individual subscribers.
The NAMS FTC uses calling pattern thresholds to determine fraud, based on:
- NPA/NXX
- NPA
- Country Code/City Code
- Country code combinations
When pre-determined, hourly, thresholds are exceeded, calls can either:
- disconnected
or
- the system notifies you for further investigation
You may also set up blacklists or whitelists to handle individual subscribers.
The NAMS Fraud Traffic Controller comes in two flavors, SIP and SS7:
NAMS Fraud Traffic Controller - SIP
The SIP version becomes an active member of your VoIP network. When required, a BYE message is sent back to the offending party, thus preventing their call. The NAMS FTC plugs into your network just like a UA, so no additional hardware is required.
NAMS Fraud Traffic Controller - SS7
The SS7 version becomes an active member of your SS7 TDM network through a proprietary interface card. When fraudulent calls are detected, a standard REL release message is transferred to the calling party, thus terminating the call.
Note: We recommend that the NAMS Fraud Traffic Controller be combined with a NAMS Firefly® for maximum fraud investigation and prevention.
