The Signaling panel provides the following configuration.

### Presence configuration

Turn on **Enable Presence** to control whether Presence is available for this project, then set:

* **Max number of instant event**: The maximum number of instant notifications sent before Signaling switches to interval mode. The value range is 8–128, with a default of 50. To request a value outside this range, contact [technical support](mailto\:support@agora.io).
* **Timed event notification interval**: How often periodic notifications are sent, in seconds. The value range is 5–300, with a default of 30.
* **Event notification debounce time**: The interval within which no presence event is triggered if a user quickly leaves and rejoins, in seconds. The default is 2.

### Storage configuration

Turn on **Enable Storage** to enable storage sync and related attribute callbacks, then set:

* **User attribute callback**: Receive callbacks when user attributes change in real time.
* **Channel attribute callback**: Receive callbacks when channel attributes are updated by any member.

### History

Turn on **Enable History** to store message history for later retrieval.

### Distributed lock

Turn on **Enable Distributed Lock** to coordinate exclusive access to shared resources across clients.

### Activate stream channels

Turn on **Enable Stream Channel** to use ordered, topic-based messaging for time-sensitive event delivery. This setting may require manual review before it becomes fully available.

Select **Save changes** to apply your updates.
