}errandThe agent makes the call and does the asking itself: a reservation, an appointment, a question, a cancellation. It only rings your person if the other side needs them (a card, a decision). Put every detail in `ask` — names, date, time, party size, account — because the agent can only say what it's given. Spends credits. Leaves a message on voicemail by default.
