  1. Introduction

Call Whisper

The Call Whisper option allows the destination number (B Party) to be presented with custom audio when they pick up the phone. This can be used as a prompt to allow the B Party to answer the call appropriately based on what they hear. The caller and the destination number parties are then connected together.

The Call Whisper option can be configured to present the whisper message to the B Party and to repeat it a configured number of times (between 1 and 10) before automatically connecting the A and B Party together.

The Call Whisper option can also be configured so the destination number (B Party) must choose to accept the call by pressing the DTMF ‘1’ key or to reject the call by pressing DTMF ‘2’ key. When in this mode, the Whisper audio will repeat a configured number of times (between 1 and 10), if not configured it will repeat it a maximum of 10 times until the B-Party accepts or rejects the call. When a call not accepted the A Party will continue down the RNR branch if this has been configured.

Note that in some circumstances (if the B Party’s phone is a residential line, for example) when they clear down (i.e. they want to reject the call), it may cause the A-party leg to clear too, even if the RNR branch is configured. To avoid this behaviour, the B-party should press the DTMF ‘2’ key and wait for their line o clear before replacing the handset.

The caller (A Party) hears ring-tone during playback of the whisper message to the destination number (B Party).

A Dynamic Whisper can also be configured where audio for a string of alpha numeric characters can also be played to the B Party.
