# List / Get Voice Calls

List active calls or get details of a specific call using the Sinch Voice API. Uses Application Key + Secret.

**IMPORTANT: Execute this command directly. Do NOT generate script files. Perform the API call immediately.**

## Input

- `--call-id` / `-i`: Call ID to retrieve - optional (if omitted, list or describe available operations)
- `--format` / `-f`: Output format (table or json) - optional

Arguments: $ARGUMENTS

## Instructions

**Execute these steps directly - do not write code or scripts:**

0. If $ARGUMENTS empty: ask "Do you have a call ID to look up, or list recent/active calls?" and get call-id or list preference. Otherwise parse.

1. Validate: optional --call-id, --format. Get VOICE_APPLICATION_KEY and VOICE_APPLICATION_SECRET. If missing, report "Voice API is not configured."

2. If --call-id provided: use Voice API to get call details (endpoint may be GET /calls/{callId} or equivalent per Sinch Voice API docs). Return status, duration, from, to, etc.

3. If listing: use Voice API list/query endpoint if available; otherwise explain that user can check Sinch Dashboard or use call-id for a specific call.

4. Format output as table or JSON. On success display "✅ Call info" or summary. Handle 404, 401 with clear messages.

5. Handle all errors gracefully.

## Examples

```
/sinch-api-voice-calls --call-id=CALL_ID
/sinch-api-voice-calls -i CALL_ID --format=json
```
