Station Features and Operation (PT/SLT)
User Manual 319
To talk to the third party after placing the current call on hold
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)."

caller (two-way) and the third party (one-way).
