Off-Hook Call Announcement (OHCA)
Description
OHCA allows you to inform a busy extension that another call is waiting by talking through 
the built-in speaker of the called party's digital proprietary telephone. If the existing call is 
using the handset, the second conversation is made with the speakerphone so that the called 
party can talk to 2 parties independently. OHCA is performed the same way as Busy Station 
Signalling (BSS) or Whisper OHCA. It depends on the telephone type used by the called party 
whether Call Waiting, OHCA or Whisper OHCA is activated by the operation. If the called 
telephone is the following, OHCA becomes active: KX-T7436 and KX-T7235.
Conditions
Class of Service programming determines which extensions can perform this feature.
If none of 3 features, Call Waiting, OHCA or Whisper OHCA, is set at the called party, the 
caller will hear a reorder tone.
