## Clear call forwarding for a line

`lines.call_forwarding.delete(strsendblue_number)  -> CallForwardingDeleteResponse`

**delete** `/api/lines/{sendblue_number}/call-forwarding`

Removes the per-line call forwarding number. After clearing, inbound calls
will fall back to the company default forwarding number (if configured).

This operation is idempotent — calling it on a line with no forwarding set
returns 200 with `forwarding_number: null`.

### Parameters

- `sendblue_number: str`

### Returns

- `class CallForwardingDeleteResponse: …`

  - `forwarding_number: Optional[str]`

    The number calls are forwarded to, or null if not set

  - `sendblue_number: str`

    The Sendblue phone number (E.164)

### Example

```python
import os
from sendblue_api import SendblueAPI

client = SendblueAPI(
    api_key=os.environ.get("SENDBLUE_API_API_KEY"),  # This is the default and can be omitted
    api_secret=os.environ.get("SENDBLUE_API_API_SECRET"),  # This is the default and can be omitted
)
call_forwarding = client.lines.call_forwarding.delete(
    "+12125550101",
)
print(call_forwarding.forwarding_number)
```

#### Response

```json
{
  "forwarding_number": "+16692138010",
  "sendblue_number": "+12125550101"
}
```
