## Get call forwarding for a line

`lines.call_forwarding.retrieve(strsendblue_number)  -> CallForwardingRetrieveResponse`

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

Returns the current call forwarding number for a dedicated phone line.

Per-line forwarding takes priority over the company default forwarding number
but is overridden by seat-level forwarding when a seat has a forwarding number set.

**Priority order:** seat forwarding → per-line forwarding → company default forwarding

### Parameters

- `sendblue_number: str`

### Returns

- `class CallForwardingRetrieveResponse: …`

  - `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.retrieve(
    "+12125550101",
)
print(call_forwarding.forwarding_number)
```

#### Response

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