Conditions
• COS programming determines which extensions can use this feature.
• This feature is available only when the calling and called extension use one of the following
telephones:
• If the Whisper OHCA feature cannot be used due to COS or telephone type, the Call
Waiting tone will be sent to the called extension. (
1.7.4.2 Call Waiting Tone)
• If the called extension does not use a KX-T7600, KX-T7500, or KX-T7400 series
telephone but forces Whisper OHCA, the announcement may be heard by the other party.
• It is possible to enable the Whisper OHCA on any telephone. However, it may not work
properly. (e.g., The voice may be heard by the other party.)
• If an extension user makes a Whisper OHCA call while the called extension has placed an
intercom call on hold, the calling extension will hear a ringback tone and the INTERCOM
button on the called extension will flash to show another call is waiting.
• While an extension is receiving the Whisper OHCA, if the extension user places the
current trunk call on hold or transfers the current intercom call or trunk call, the Whisper
OHCA will become disabled and the calling extension will start to hear a ringback tone.
• While an extension is receiving the Whisper OHCA, if the extension user places the
current intercom call on hold, the called extension can talk to the calling extension through
the handset.
