# Monitor live calls

> See every call in progress, listen in silently, and whisper guidance the caller never hears.

The **Live** page (`/dashboard/live`) under **Engagement** lists every
call currently in progress — who's talking to which agent, in which
direction, and for how long. From there you can join any call as a
silent listener and coach the agent mid-call.

## The live board

Each row shows the **agent**, **direction** (inbound/outbound),
**caller**, **callee**, a ticking **live duration**, and when the call
started. The page refreshes itself every few seconds, and a "live"
counter in the header tracks the total. Calls placed directly through
the API without an agent show as *API / Webhook*.

Click **Listen** on a row to open that call's detail page, where the
live controls appear.

<Note>
  Live supervision works on real calls only — in demo mode the board
  shows simulated calls and the listen/whisper controls are disabled.
</Note>

## Listen in

**Listen in** joins the call as a hidden, listen-only participant:

* Neither the caller nor the agent is affected — nothing on the call
  changes and nobody is notified.
* The recording is unaffected; your listening never appears in it.
* A **LIVE** indicator shows while connected. Click **Leave** to drop
  out; if your connection blips, the session reconnects automatically.
* When the call ends, the session ends with it.

## Whisper to the agent

While listening, a **Whisper to agent…** box appears next to the live
controls. Type a short instruction (up to 500 characters) and press
**Send**:

* The agent receives your text as **private mid-call guidance** and
  incorporates it into the conversation.
* **The caller never hears or sees the whisper** — it changes what the
  agent does next, not the audio on the line.
* You'll see *Whisper sent* on delivery, or *Call ended* if the call
  finished before the whisper arrived.

Whispers are ideal for live corrections — "the discount code is
SPRING24", "offer to escalate", "wrap up, this is a spam call" — without
taking the call over.

<Tip>
  Listen and whisper are also available programmatically via
  `POST /v1/calls/{id}/listen` and `POST /v1/calls/{id}/whisper` — see
  the [calls API reference](/api-reference/calls).
