This feature allows your AI (in your cloned voice) to answer calls and politely delay the conversation. 
Instead of talking immediately, your AI will respond with a short excuse and let the caller know you’ll 
call them back soon.  Calls made with Buy Time are automatically limited to 1 minute. This ensures the caller does not have time to notice that it’s not actually you speaking. The AI gives your excuse, then ends the call — keeping the interaction short and believable.
