General Features
Whisper OHCA
Description
When attempting to call a busy extension, Whisper OHCA allows the extension user to notify
the busy party through the handset, which will only be heard by the party. Only KX-T7400
series telephone users can send or receive the Whisper OHCA.
Conditions
• Class of Service programming determines which extensions are able to perform this feature.
• You can select receiving Call Waiting tone, Off-Hook Call Announcement (OHCA),
Whisper OHCA or none of these at your extension. However, the setting may change
depending on each telephone setting or the telephone type as listed below.

• Only the Voice Mail extension can only execute BSS regardless of the setting.
• If the Whisper OHCA sender does not use a KX-T7400 series telephone, it will work as
OHCA. If the receiver does not use a KX-T7400 series telephone, it may not work properly.
(E.g., the announcement may be heard by the other party.)
