[VoiceOps] Broadsoft SIP Trunks and ILD Fraud

[Mark Holloway]

The IP PBX (or on-prem SBC) should be registering to Broadworks using the Pilot number.  The SBC in your core will only allow SIP Invites from the registered device.  If you have non-registered SIP Trunks in Broadworks this is very dangerous.

These smaller SIP trunks groups when compromised are able to run up HUGE fraud bills even tho they only have 5 or 6 SIP trunks. Needing to know if anyone else is seeing this that has Broadsoft and what was done to protect yourselves?
