Toll Fraud and Account Security Policy

Effective June 1, 2026

This policy applies to voice, mobile/eSIM, hosted PBX, SIP, API, voicemail, forwarding, and related Services. Customers are responsible for securing accounts, devices, credentials, extensions, trunks, applications, and downstream access against toll fraud and unauthorized use.

Required safeguards

• use unique, strong credentials and multi-factor authentication where available;
• restrict administrative, SIP, API, and network access to authorized users and expected sources;
• disable unused features, destinations, forwarding rules, accounts, and credentials;
• apply reasonable calling, spending, geographic, concurrency, and rate controls;
• monitor usage and alerts and investigate unexpected traffic promptly; and
• notify MultiTEL immediately of suspected compromise and rotate affected credentials.

MultiTEL may block destinations, rate-limit traffic, suspend Services, reset credentials, or require additional controls where fraud or compromise is suspected. Such controls reduce risk but cannot guarantee prevention. Charges generated through valid Customer credentials or systems remain the Customer's responsibility except to the extent applicable law or a written agreement provides otherwise.
