International calls are the main target of toll fraud, where someone gets into a phone system and runs up expensive calls on your account. To limit the risk, calls to high-risk destinations are blocked by default, and you can ask for other destinations to be blocked too. This page also lists the documents you need to register a phone number in another country.

## High-risk destinations (blocked by default)

Calls to these destinations are blocked by default because they're often used for toll fraud.

To ask for one of these destinations to be unblocked, [raise a support ticket](https://kb.voipcloud.online/au/support/support-tickets/). The support team decides case by case after checks, and may ask for identity documents or a deposit.

## Restrict international calls

International dialling is turned on by default on every call plan. If your business doesn't call overseas, or only calls a few countries, ask the support team to block the destinations you don't use. [Contact the support team](https://kb.voipcloud.online/au/support/support-tickets/) to ask.


Blocking or allowing calls to overseas destinations is a high-risk request. The support team emails you a code to confirm it's you before making the change. See [Two-factor authentication](https://kb.voipcloud.online/au/security/two-factor-authentication/#when-you-contact-support).

## Protect yourself from toll fraud

- **Use strong passwords** for the portal, SIP devices and SIP trunks. Don't reuse them.
- **Keep passwords safe.** Don't store them in plain text files, write them on paper or send them by email.
- **Turn on 2FA** for every portal administrator. See [Two-factor authentication](https://kb.voipcloud.online/au/security/two-factor-authentication/).
- **Lock SIP devices and trunks to your IP address** with **Allow connection from one IP address only** in [Devices](https://kb.voipcloud.online/au/pbx/settings/devices/) (under **Advanced parameters**) and in the [SIP trunk](https://kb.voipcloud.online/au/pbx/accept-make-divert/sip-trunk/) settings.
- **Block international destinations you don't call** (see above).
- **Change passwords regularly,** at least once every quarter. For a SIP device or SIP trunk, click **Generate a new password**, then apply the configuration.

If you see calls you didn't make, follow [After a security incident](https://kb.voipcloud.online/au/security/after-a-security-incident/).

## Registering phone numbers in other countries

Some countries require the end user to register before a local phone number (DID) can be used. The table shows which documents you need for each number type. The numbers refer to the [document list](#required-documents) and the letters to the [conditions](#conditions) below.

**Note:** These requirements were last updated on 6 December 2021, with condition m added in 2026. They may change.

- **–** means no registration is needed.
- **N/A** means the number type isn't available in that country.

To order a number in another country, see [International numbers](https://kb.voipcloud.online/au/services/phone-numbers/international-numbers/).
