Description
An extension user can speak to a busy extension through the handset.
Conditions
• Class of Service (COS) programming determines which extensions can use this feature.
• This feature is available when the calling and called extension use one of the following telephones:
– KX-T7600 series
– KX-T7400 series
– KX-NT series
• If the Whisper OHCA feature cannot be used due to COS or telephone type, a call waiting tone will be
sent to the called extension. (→ 1.3.10 Call Waiting Tone)
• If the called extension does not use one of the telephones listed above, but forces Whisper OHCA, the
announcement may be heard by both parties.
• It is possible to enable Whisper OHCA on any telephone, however, it may not function properly (the
caller's voice may be heard by both callers, for example).
• While an extension is receiving a Whisper OHCA, if the extension user places the current CO line call
on hold or transfers the current intercom call or CO line call, the Whisper OHCA will become disabled
and the calling extension will hear a ringback tone.
• While an extension is receiving a 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.
