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.
<Example> If the user selects 3 (Whisper OHCA mode);
–If using the KX-T7400 series telephone handset...........Whisper OHCA
–If using the KX-T7400 series telephone SP-PHONE......Call Waiting tone
–Other....................................................................OHCA, Call Waiting tone
• 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, the announcement may
also be heard by the other party.
• It is possible to enable the Whisper OHCA by any telephone by system programming.
However, it may not work properly. (E.g. the announcement may be heard by the other
party.)
