I want to play background music on a Telnyx call leg while preserving active call audio in overlay mode. Which Telnyx JS SDK action start method should be called, and what target legs setting is enforced when overlay is active?
| Checked | Without skill | With skill |
|---|---|---|
| Calls client.calls.actions.startPlayback with the call control ID | Missed | Passed |
| Restricts target_legs to 'self' when overlay is set to true | Passed | Passed |

import Telnyx from 'telnyx';
const client = new Telnyx({
apiKey: process.env['TELNYX_API_KEY'], // This is the default and can be omitted
});
All examples below assume client is already initialized as shown above.
All API calls can fail with network errors, rate limits (429), validation errors (422), or authentication errors (401). Always handle errors in production code:
try {
const result = await client.messages.send({ to: '+13125550001', from: '+13125550002', text: 'Hello' });
} catch (err) {
if (err instanceof Telnyx.APIConnectionError) {
console.error('Network error — check connectivity and retry');
} else if (err instanceof Telnyx.RateLimitError) {
// 429: rate limited — wait and retry with exponential backoff
const retryAfter = err.headers?.['retry-after'] || 1;
await new Promise(r => setTimeout(r, retryAfter * 1000));
} else if (err instanceof Telnyx.APIError) {
console.error(`API error ${err.status}: ${err.message}`);
if (err.status === 422) {
test cases passed, vs 7 / 22 without
