**Important Note**
_If you find yourself in a situation where **ACBClientCallDelegate** is not being set in time, please ensure that you are calling it as soon as the call is available during your call flow. In some scenarios, you may need to set it asynchronously via the *setDelegate(callDelegate:)* method in order to make sure it is set properly in the SDK, but please use this method as a last resort._
