The whisper message is an audio file that will be played to the operator when the call is connected, which can announce the number/campaign that the call is coming through from. This feature allows the operator to know that the call is coming through a Delacon number instead of the regular business phone number. The caller will not have any knowledge of this message being played, from their point of view the phone will continue to ring before the caller and operator are connected.
Please be aware that as the whisper message plays as soon as the call connects to the termination point, this feature cannot be used where the connection is not to a person. This includes IVRs, hunt groups, voicemails and any other system that connects the call without human interaction.
The whisper message can be enabled or disabled in the Delacon portal by visiting Menu > Services > Edit > Whisper
