# How can I block the destinations Users can call?

As an administrator, you can block certain call destinations for yourself and your team members. Whether it's expensive international destinations or specific premium-rate numbers, you have full control over call restrictions.

To manage call barring settings

1. Go to **Account Administration** and select **Users**.
2. Choose the team member for whom you want to set call restrictions.
3. Click **Permissions** on the left-hand side to access call barring options.

#### Configuring Call Barring

You can toggle different call barring options using the provided switches. Changes may take up to **15 minutes** to take effect.

#### International and Premium-Rate Numbers

Enabling this option prevents users from calling premium-rate numbers (e.g., 01801, 01802, 01803) and all international numbers. Pricing details for outbound calls are available in our rate list.

**Important:** Some premium-rate numbers (e.g., 0137, 0138, 01212, 01807, 0185, 0181, 0188, 0900, and 118xx) are always blocked from sipgate's network and do not need to be manually restricted.
{% endhint %}

#### Chargeable Destinations

When enabled, users can only make internal calls or calls included in an active flat rate (e.g., Germany-wide flat rate, mobile flat rate).

#### High-Cost International Numbers

By default, newly created users have high-cost international destinations blocked. If a user attempts to call a blocked destination, they will hear the following message

***"Hello, for security reasons, some international destinations are blocked on your sipgate account. You will soon receive a link to lift these restrictions."***

Additionally, the administrator will receive an email notification.\
The list of blocked destinations is regularly updated, and we do not provide a full list of affected countries. However, destinations typically classified as **high-cost** do not include EU countries, the USA, or China.

#### Roaming Outside the EU (Mobile)

Outgoing and incoming calls using a sipgate SIM card outside the EU are blocked due to roaming charges.\
By adjusting these settings, administrators can control costs and enhance security for their team's telephony setup.
