General Features
176 Features Guide
Off-Hook Call Announcement (OHCA), Whisper
Description
This is a variation of the OHCA feature.
The difference is, OHCA provides two-way communication, but Whisper OHCA provides
one-way (from the calling extension to the called extension) communication.
Conditions
• Call Waiting
Whisper OHCA is only effective when the called extension has set Call Waiting feature.
If not, the caller will hear a reorder tone after dialing the extension number.
• Non-KX-T7400 cases
Whisper OHCA is activated when both calling and called extensions are using the KX-
T7400 series PTs by default. If either one of them is a non-KX-T7400 series PT, OHCA
(when the called extension is an OHCA-capable PT) or BSS is activated.
However, Whisper OHCA between two non-KX-T7400 series PTs can be enabled by
System Programming < Section 2.8 System Option, "32. Whisper OHCA to extensions
other than T74/75XX>.
• Enabling Feature for Any PT
It is possible to enable the Whisper OHCA by any PT by System Programming. But it may
not work properly (e.g., the OHCA may be heard by unintended parties.)
• Conference Trunk
An idle conference trunk is required to perform this feature.
• BSS / OHCA / Whisper OHCA
If an extension user dials "1" while hearing a busy tone, BSS or OHCA or Whisper OHCA
will be activated at the called extension. This is determined by the following conditions.
• BSS, OHCA and Whisper OHCA do not function, if the other extension is a DN type PT.
