# Global carriers

*Global carriers* are [carriers](https://docs.cognigy.com/ai/administer/access/speech-and-telephony.md#carriers) at [organization level](https://docs.cognigy.com/ai/administer/access/admin-center/global-resources/overview). You can assign them to projects and share them across your organization.

## Prerequisites

* Have the `admin` [global role](https://docs.cognigy.com/ai/administer/access/admin-center/access-control.md).
* Have voice features activated for your organization.

## Work with global carriers

In the Admin Center, go to **Resources > Carriers**. You can add, edit, and delete global carriers.

The form is the same as for project-level carriers. For the carrier settings, see [Carriers](https://docs.cognigy.com/ai/administer/access/speech-and-telephony.md#carriers).

Phone numbers, recording buckets, and the carrier **Test call** tab are project-level. They aren't available in the Admin Center.

### Check carrier usage

The **Used in** column shows the projects that use a carrier. It shows **Not used** if nothing uses it.

You can't delete a carrier that is in use. Remove the carrier from those phone numbers first.

## Assign to projects

To make a global carrier available in a project, assign it to the project. For the steps, see [Assign global resources to projects](https://docs.cognigy.com/ai/administer/access/admin-center/global-resources/overview#assign-global-resources-to-projects).

## Use in projects

In **Manage > AI & Voice Providers > Telephony > Carriers**, global carriers appear with a **Global** badge. Projects can use them, for example when you add a phone number.

Projects can't edit or delete global carriers. To view the settings, open the carrier. In a project, you can set an active global carrier with an outbound gateway as the Click To Call default.
