Is there a limit on how many outbound AI calls I can make, and can the AI transfer a call to a person?

There is no cap on the number of outbound AI calls. A volume such as 10,000 outbound AI calls a month is no problem. Phone usage is billed per minute, and how many calls you can place in an hour depends on call length and your concurrent lines: five lines (five calls at the same time) are included, and extra lines cost $7 each for the months you use them.

AI outbound calling needs an opt-in. Make sure the people you call have agreed to be called. The AI dialer is not for cold calling.

When someone answers, the AI can transfer the call to a live rep, or it can qualify the person, book an appointment and then transfer. It can also act as an SDR and hold the conversation itself. In the workflow builder you can have it ask questions and save the answers, forward the call, or use a decision node that routes the call based on the answers.

If you want a person to do the calling instead, use the power dialer, which goes through your contacts one at a time, back to back, on the built-in web phone.
