To use Answer Bots, your phone carrier needs to support a feature called Conditional Call Forwarding (CCF). This forwards your busy, unanswered, and unreachable calls to Robokiller. Here's how to enable Answer Bots:

1. Open the Robokiller app and select Settings.
2. Tap Answer Bots and toggle the switch to enable.
3. Select an Answer Bot from the list or choose a category to filter through the options.

If your phone carrier supports CCF, but you don't have the option to enable Answer Bots in the app, please ensure you're subscribed to Robokiller Premium, as Answer Bots is an exclusive feature for premium subscribers. Unfortunately, if your carrier doesn't offer this feature, Answer Bots won't be available.
