# Phone Call Config

> Connect a Twilio number for candidate phone interviews.

Connect a Twilio number to let candidates complete AI interviews over the phone.

## Twilio credentials

Update the **Account SID** and **Auth Token** only when credentials rotate. Once saved, your credentials are masked for security (e.g., `AC69********563d`).

## Calling number and cost limit

Change the outbound phone number or max price without resubmitting credentials. This lets you adjust which number candidates see and control per-call costs independently from your Twilio account settings.
