How does enabling "Call Waiting" function in 3CX?

Enabling the "Call Waiting" function in 3CX is designed to enhance user call management by allowing users to receive a second incoming call while they are already on a call. When this feature is active, users will receive an alert when a new call comes in, giving them the option to either hold the current call and answer the new one or to decline the incoming call. This capability is crucial for businesses that require staff to remain accessible while handling multiple calls, improving communication efficiency.

The other options do not accurately describe the functionality of Call Waiting. For instance, hearing a voicemail during a call, preventing further incoming calls, or directing the second call to a different extension do not reflect the purpose or operation of the Call Waiting feature in 3CX. This distinction makes it clear that option B addresses the intended and practical use of Call Waiting within the system.
