Conditions
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.
If Do Not Disturb (DND) feature is set at the called extension, you hear DND tone. In this 
case, to execute OHCA, you must first activate Do Not Disturb (DND) Override feature 
before OHCA is available.
Call Waiting
OHCA is only effective when the called extension has set Call Waiting feature. If not, you 
will hear a reorder tone after dialing 1.

This feature works when the called extension is having a conversation or a conference with 
extension(s) or CO line(s) using the handset.

BSS, OHCA and Whisper OHCA do not function, if the other extension is a DN type PT. Calling extension Called extension

4.3.50 Off-Hook Call Announcement (OHCA) —Whisper
This is a version of the OHCA feature. The difference is, OHCA provides two-way 
communication between two extensions but this feature provides one-way communication. 
When this feature is activated, the called party can hear callers voice through the handset but 
the caller cannot hear the called partys voice.
 By default, this feature is available only when both calling and called extensions are using KX-
T7400 series PTs.

Conditions
This feature can be enabled to any PTs (other than KX-T7400 series PT) by System 
Programming.
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 T74XX>. 

BSS, OHCA and Whisper OHCA do not function, if the other extension is a DN type PT.
Other conditions are the same as that of Off-Hook Call Announcement (OHCA).
