SIP Toll Fraud
Short definition
SIP Toll Fraud: Unauthorised use of SIP accounts or calling routes, often causing unwanted charges.
Meaning and how it works
Toll fraud can exploit stolen credentials or unrestricted routes; destination controls and alerts reduce exposure. Protecting telephony and customer data combines technical controls, access rights and organisational processes. Different communication channels can require different safeguards.
Business applications
- Business scenario:
A monitoring system detects unusual international calling and blocks a suspicious account.
What to check before implementation
Review lawful data handling, key and access management, retention periods, audit trails and recovery procedures. No single mechanism replaces an overall security policy.
