 The TTL configuration allows the management of push notifications' lifecycle, reducing the need for frequent token renewals while ensuring that the communication channel between the application and its users remains open and reliable for extended durations.

 Once the register push notification API is called when the device token information is saved in Registrar. After TTL lifespan ends, the device endpoint information is deleted. Any incoming calls on those devices can't be delivered to the devices if those devices don't call the register push notification API again.
 
 In case that you want to revoke an identity you need to follow [this process](../../concepts/identity-model.md#revoke-or-update-access-token), once the identity is revoked the Registrar entry should be deleted.

 # Connect Calling Native Push Notification with Azure Event Grid
-
 With Azure Communication Services, you can receive real-time event notifications in a dependable, expandable, and safe way by integrating it with [Azure Event Grid](https://azure.microsoft.com/services/event-grid/). This integration can be used to build a notification system that sends push notifications to your users on mobile devices. To achieve it, create an Event Grid subscription that triggers an [Azure Function](../../azure-functions/functions-overview.md) or webhook.
