When you are forwarding business calls, you'll often want to add a call whisper.
This involves playing a message to the callee while the caller continues to hear ringing. It can provide additional information such as the source or purpose of the call to the callee before the call begins and even allow the callee to accept or reject the call based on that information.
Any nodes you connect after a 'Forward Call' block will run silently before the call is forwarded.
