Vio auto-dials at the scheduled time and retries the ones nobody answers. # Callbacks **Callbacks are follow-up calls your agent scheduled for itself during a conversation — when a caller says "call me back in 30 minutes," the agent books it, and Vio dials at that time automatically.** The Callbacks view lists every one of these, with its status. Unlike an [**outbound campaign**](/vio/telephony/outbound-campaigns), which you launch from a list, a callback is created by the agent mid-call. ## How a callback happens 1. During a call, the caller asks to be called back later ("try me after lunch," "call me tomorrow at 4"). 2. The agent uses the **Schedule a callback** tool to book the follow-up — see [**Tools**](/vio/agents/tools). 3. At the scheduled time, Vio **auto-dials** the caller. 4. The **same agent** answers, with the **earlier conversation injected** so it picks up naturally instead of starting cold. Because the prior conversation carries over, the callback feels like a continuation — the agent already knows who it's calling and why. ## Callback statuses A callback moves through these states: | Status | Meaning | |---|---| | **Scheduled** | Booked and waiting for its time. | | **Dialing** | Vio is placing the call now. | | **Completed** | The callback connected and the conversation ran. | | **No answer** | The caller didn't pick up — Vio retries up to a limit. | | **Failed** | The call couldn't be placed. | | **Cancelled** | You cancelled it before it fired. | No-answers are **retried automatically** up to a set limit, so a single missed pickup doesn't drop the follow-up. ## Cancel a pending callback ### Open the Callbacks view Select **Callbacks** in the sidebar to see scheduled and past follow-ups. ### Cancel the one you don't want On any **Scheduled** callback, choose **Cancel**. Vio won't dial it, and its status becomes **Cancelled**. Callbacks already **Dialing** or **Completed** can't be cancelled. Callbacks dial from a number with **outbound enabled**. If your agent schedules callbacks but they fail to place, check that its number has outbound switched on — see [**Phone numbers**](/vio/telephony/numbers). ## Frequently asked **Q. How is a callback different from an outbound campaign?** A **campaign** is a batch you launch from a contact list. A **callback** is a single follow-up the **agent booked itself** during a live conversation. Both dial out, but callbacks are created on the fly, one at a time. **Q. Will the agent remember the earlier conversation?** Yes. The prior conversation is injected into the callback, so the same agent continues naturally rather than starting over. That's the whole point — the caller shouldn't have to repeat themselves. **Q. What happens if the caller doesn't answer the callback?** It's marked **No answer** and **retried automatically** up to a limit. If every retry misses, it stops there and you'll see the final status in the list. ## Next step Every callback that connects is recorded like any other call — read it in [**Call logs**](/vio/call-logs), and enable the tool in [**Tools**](/vio/agents/tools).
