As an administrator, you can subscribe to Call Notify. Call Notify is triggered when a call is answered.
The Call Notify webhook enables you to automate sending either a GET or POST method to your CRM to request that the contact information for the current inbound or outbound Dialer call be displayed in the CRM browser window.
The Call Notify webhook initiates when a conversation starts. For outbound calls, this is when the contact answers. For inbound calls, this is when the call is connected to an agent.
