1.12.3 OHCA (Off-hook Call Announcement)

Description
An extension user can talk with a busy extension through the built-in speaker and microphone of the called
party's proprietary telephone (PT). If the existing call is using a handset, a second conversation is made
using the speakerphone and microphone so that the called extension can talk to both parties.
Conditions
• Class of Service (COS) programming determines which extensions can use this feature.
• This feature is available when the called extension uses one of the following telephones:
– KX-T7625, KX-T7630, KX-T7633, KX-T7636
– KX-T7436
– KX-T7235
• Off-hook Call Announcement (OHCA) cannot be used when:
a)
The OHCA mode of the caller's COS is set to "Disable".
b)
The called extension's telephone is not compatible with this OHCA.
c)
The called extension is a digital proprietary telephone (DPT) which is connected via a USB Module
to a computer running PC Console or PC Phone.
d)
The called extension is in a Digital XDP connection.
In these cases, a call waiting tone is sent to the called extension. (→ 1.3.10 Call Waiting Tone)
• While an extension is receiving an OHCA, if the extension user places the current CO line call on hold
or transfers the current intercom call or CO line call, the OHCA will become disabled and the calling
extension will hear a ringback tone.
• While an extension is receiving an OHCA, if the extension user places the current intercom call on hold,
the called extension can talk to the calling extension through the handset.
