AI receptionist books but can't reschedule: a missing tool, not a broken voice
A builder spent four days on an AI receptionist with Retell and cal.com: booking works, but rescheduling and cancelling does not. The thread points to the usual culprit — the agent was only given a create-booking tool and improvises the rest — and suggests wiring explicit reschedule and cancel tools that take the original booking ID before touching the voice prompt.
