20.1.3 Whisper OHCA
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-DT300 series
–KX-T7600 series
–KX-T7400 series
–IP-PT 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. (® 3.1.10 Call Waiting Tone)
•If the called extension does not use a KX-DT300, KX-T7600 or KX-T7400 series telephone or an IP-PT,
but forces Whisper OHCA, the announcement may be heard by the other party.
•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.

20.1.4 Wireless XDP Parallel Mode
Description
A portable station (PS) can be used in parallel with a wired telephone, i.e., a digital proprietary telephone (DPT),
analog proprietary telephone (APT), or single line telephone (SLT), allowing an extension user to make or
receive calls with either the wired telephone or the PS. The PS will use the same extension number as the
wired telephone, and many of the wired telephone’s extension settings (Call Forwarding [FWD], Class of
Service [COS], etc.) are also used by the PS.
