 ## Number assignment
 
 Since the `IncomingCall` notification doesn't have a specific destination other than the Event Grid subscription you've created, you're free to associate any particular number to any endpoint in Azure Communication Services. For example, if you acquired a PSTN phone number of `+14255551212` and want to assign it to a user with an identity of `375f0e2f-e8db-4449-9bf7-2054b02e42b4` in your application, you'll maintain a mapping of that number to the identity. When an `IncomingCall` notification is sent matching the phone number in the **to** field, you'll invoke the `Redirect` API and supply the identity of the user. In other words, you maintain the number assignment within your application and route or answer calls at runtime.

+## Subscribe to IncomingCall event
 
 IncomingCall is an Azure Event Grid event for notifying incoming calls to your Communication Services resource. To learn more about it, see [this guide](../../concepts/voice-video-calling/incoming-call-notification.md). 
 1. Navigate to your resource on Azure portal and select `Events` from the left side menu.
 1. Select `+ Event Subscription` to create a new subscription. 
 1. Filter for Incoming Call event. 
 1. Choose endpoint type as web hook and provide the public url generated for your application by ngrok. Make sure to provide the exact api route that you programmed to receive the event previously. In this case, it would be <ngrok_url>/api/incomingCall.
