hisper 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-T7436 handset ..........................Whisper OHCA
– If using the KX-T7436 SP-PHONE ...................Call Waiting
– Other...................................................................Call Waiting
• The Voice Mail extension can execute only BSS irregardless 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.)
