International restrictions

Which international destinations are blocked, how to restrict international calls, and what you need to register phone numbers in other countries.
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.

To ask for one of these destinations to be unblocked, raise a support ticket. The support team decides case by case after checks, and may ask for identity documents or a deposit.
Restrict international calls
Section titled “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 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.
Protect yourself from toll fraud
Section titled “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.
- Lock SIP devices and trunks to your IP address with Allow connection from one IP address only in Devices (under Advanced parameters) and in the 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.

Section titled “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 and the letters to the conditions below.
- – means no registration is needed.
