# Channels settings

> Manage workspace phone numbers and email domains.

Use **Settings → Channels** to provision and review shared communication assets. These assets are later assigned to inboxes, outbound campaigns, appointment reminders, and personal inboxes.

## Phone numbers

Phone numbers can support SMS, voice, or both. A number can be marked as:

* **In use** when it is assigned to an inbox, outbound sender, personal inbox, or another workflow.
* **Appt. Reminders** when it is reserved for appointment reminder calls or SMS.
* **Archived** or **Archiving** when it is being removed from active use.

To add a phone number:

1. Go to **Settings → Channels**.
2. Click **Add phone number**.
3. Choose **United States** or **Canada**.
4. Optionally enter an area code.
5. Select an available number.
6. Click **Add number**.

## Email domains

Email domains are custom domains or subdomains used for Clearline-managed email addresses.

Domain statuses include:

| Status       | Meaning                                                                           |
| ------------ | --------------------------------------------------------------------------------- |
| **Pending**  | DNS records still need to be configured or verified.                              |
| **Partial**  | Some DNS checks passed, but not all.                                              |
| **Verified** | The domain is ready for sending and receiving.                                    |
| **Failed**   | Verification failed and needs attention.                                          |
| **In use**   | At least one inbox, outbound sender, or appointment notification uses the domain. |

To add a domain:

1. Go to **Settings → Channels**.
2. Click **Add custom domain**.
3. Enter the domain, such as `example.com` or `reply.example.com`.
4. Configure the DNS records shown by Clearline.
5. Wait for the domain to become **Verified** before using it.
