# Webhooks & Events

Cloud Voice can notify your systems when things happen on your account, by delivering events to an HTTPS endpoint you control. Events cover the telephony lifecycle, trunk registrations, call activity, and fax transmission status, and are dispatched asynchronously from a delivery queue so event bursts don't get lost.

## Event types

| Category | Examples |
| --- | --- |
| **Registration** | A Register trunk comes online or drops its registration |
| **Calls** | Call lifecycle events on your trunks |
| **Fax** | Transmission progress and final status of sent and received faxes (see [Faxing over SIP](/sip/fax/)) |

The trunk registration events are the same signal that powers the dashboard's live registration status and **Trunk Health** widget, webhooks let your own monitoring consume it too.

### Full event catalog

*Detailed event list and payload schemas coming soon.*

## Configuring an endpoint

*Detailed steps coming soon.*

:::tip
Use a dedicated HTTPS endpoint that responds quickly with a success status and processes the event afterward, slow handlers are the most common cause of delivery problems.
:::

## Delivery & retries

Events are queued and delivered asynchronously, so momentary spikes in call volume don't drop notifications.

*Retry schedule and delivery-guarantee details coming soon.*

## Verifying deliveries

*Signature verification details coming soon.*

:::note
If you need to poll instead of receiving pushes, for example for trunk statistics or fax status, the same data is available through the [API](/sip/api/).
