International calling is restricted by default
International calling is a primary target for fraud. We block it by default, and you turn on only the countries you need.

A common fraud pattern works like this: a bad actor gets access to a business's phone system or API credentials, then places calls to expensive international premium-rate numbers they control. The business is stuck with a massive bill for calls they never made.
To prevent this, we restrict outbound international calling by default on every 365 Agents account. You enable only the specific countries you actually need.
How to enable international calling
Dashboard → Security → International Dialing → Enable Countries. Pick only the countries your business actually needs to reach.
Countries we restrict most strictly
About 40 countries are known for high rates of phone fraud. We require additional verification before enabling calls to any of these — including some European countries (Lithuania, Latvia, Czech Republic) and many smaller Caribbean and African nations.
Additional protection available
Per-call duration cap on international calls (default 15 minutes)
Daily spending cap on international calls
Required authorization code before any international call (available on Enterprise plans)
If you need international calling legitimately
Reach out to your account manager. We'll work with you to enable exactly what you need, nothing more.
