Introduction

CallingClient module in Calling SDK provides inbound and outbound call functionality on registered lines. For every call, a call instance is created and then used to dial the call, listen for events. This document covers how we obtain the call instance and use it in inbound/outbound calls.

Call Object

Once the lines are registered, call functionality is available on any of the lines. Use the makeCall method is invoked on a line. For inbound call, when the client receives a call from Webex Calling, a call instance is returned within the payload of an event from the Calling SDK.

The call instance provided by the Calling SDK is of type ICall. A call instance provides a variety of methods to the developer that take specific actions and move the call through various states.
