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 example
A monitoring system detects unusual international calling and blocks a suspicious account.
What to consider
Review lawful data handling, key and access management, retention periods, audit trails and recovery procedures. No single mechanism replaces an overall security policy.
