What is a Whisper? You can read more about it here. 

 

Can I use the Whisper if my answering number has an IVR or a PBX or an automated answering system? 

When a call reaches a Kaisa number with the whisper feature enabled, as soon as the call is answered (whether by a person or a machine) we start playing the audio message while we continue presenting a ringing tone to the caller. When the whisper is over, we bridge the call and we'll connect both ends.

If the answering number in your side has an automated answering system or switchboard, our system will present the whisper message (if applicable for the receiver) the moment the call is answered, and any pre-recorded message in your end will play simultaneously against our whisper. When our message ends and we bridge the call, any recorded messages or IVR options would be ongoing or already over by then, affecting the caller's experience. 

We recommend disabling any IVR messages or automated answering if you plan to use the Whisper feature with Kaisa.
