# How CallWhiz AI agents take actions mid-call

CallWhiz AI agents call your systems mid-conversation and speak the result back: calendars, customer and order lookups, CRM records and any internal API you give them as an action. Actions that change something can require the caller's spoken confirmation first.

**In short:** Agents call your systems mid-conversation, booking, looking up, updating, creating, and speak the result back.

## Definitions

- **Action:** A system call the agent can make during a conversation, described with its parameters and the words to use while it waits for the result.
- **Read-back-and-confirm gate:** Before an action that changes something, the agent reads the change back and waits for the caller's spoken confirmation.

## What it does

- Book, reschedule and cancel against a real calendar, with time zones handled.
- Look a customer up, check an order or a balance, and answer with what the system actually returns.
- Create or update a record in your CRM while the call is still running.
- Any internal API can be given to an agent as an action, with the words it should use while it waits.
- Actions that change something can be made to require the caller’s spoken confirmation first.

## How it works

Each action is described to the agent with its own parameters and a natural “while I check that…” line, so a slow backend sounds like a person checking rather than dead air. Sensitive actions sit behind a read-back-and-confirm gate.
