# Caller ID

> Choose which number shows on outbound calls, and set a caller-ID name.

When you place a call, Custral decides which of your numbers appears as the
caller ID. You pick the line you call from, and set the **business name** you'd
like displayed.

## Choosing the outbound line

In the dialer, the **Line** picker chooses the number you call from. Your
selection is **remembered on this device**, so the dialer reopens on the same
line.

## How resolution works

For every outbound call the caller ID resolves in this order: the line you
picked → your default/first line → a workspace fallback number. The same logic
applies to calls placed by **workflows and sequences**, so automated calls use a
sensible line too.

## Outbound caller-ID name (CNAM)

Edit a number under **Settings → Phone & SMS → Numbers** and set **Outbound
caller ID name (CNAM)** to the business name you'd like shown (e.g. "Acme
Corp").

<Warning>
  Custral stores the name you want displayed, but **what actually appears on the recipient's handset is controlled by
  carrier CNAM databases**, not by Custral per call. Displaying a business name reliably requires CNAM / branded-calling
  registration through the carrier (a separate approval process). Treat this field as your desired value, not a
  guarantee.
</Warning>

## Verified caller IDs

To call from a number you own elsewhere (not purchased in Custral), verify it
under **Settings → Phone & SMS → Settings → Verified caller IDs**. Once
verified, it becomes selectable as an outbound line.

## Troubleshooting

| Symptom                                      | Likely cause                        | What to check                                                                                   |
| -------------------------------------------- | ----------------------------------- | ----------------------------------------------------------------------------------------------- |
| Calls show the wrong number                  | A different line is selected        | Switch the dialer **Line** picker.                                                              |
| My business name isn't shown                 | CNAM isn't registered with carriers | The name is stored, but handset display needs carrier CNAM registration. See the warning above. |
| The dialer keeps reopening on the wrong line | A stale persisted selection         | Pick the line you want; the new choice is saved for this device.                                |
| A workflow call used an unexpected number    | The action's channel/pool selection | Check the call action's channel/pool, then the resolution order above.                          |
