News
VoIP toll fraud is when attackers hijack your SIP credentials or PBX to make expensive international calls on your dime—often overnight—so prevention is about locking the front door and watching the meter.
Definition: Toll fraud is unauthorized use of a phone system to place calls (usually premium/international) for profit; in VoIP it exploits weak SIP credentials, open ports, or misconfigured trunks.
| Vector | Weakness |
|---|---|
| Default credentials | admin/admin on SIP accounts |
| Open SIP ports | PBX exposed to the internet |
| Unrestricted outbound | No destination/rate limits |
| No monitoring | Fraud runs undetected for hours |
Newrock SBC enforces access control and topology hiding; OM-series supports account lockout and rate controls, and UMS helps spot anomalies across sites.
Usually the system owner—carriers rarely refund toll fraud losses.
Both need hardening; cloud shifts some responsibility to the provider.
Change default credentials and put an SBC/firewall in front of SIP.
Set thresholds and alerts on call count/cost; review logs daily.
Toll fraud is preventable, not inevitable. Strong credentials, an SBC at the edge, outbound limits, and alerting turn a costly nightmare into a non-event.
