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
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 two parties independently. OHCA is
performed the same way as Busy Station Signaling (BSS). 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 one of the following, OHCA
becomes active: KX-T7436, KX-T7235.
Conditions • Class of Service programming determines which extensions can
perform this.
• If none of three features, Call Waiting, OHCA or Whisper OHCA is set
at the called party, the caller will hear a reorder tone.
