This feature is only available if the called extension has set the “Call Waiting” feature.

• Depending on the other party’s telephone, the “Off-Hook Call Announcement (OHCA)” and the “Whisper

OHCA” functions can be applied. You can talk to the other party through the speaker and the microphone

(OHCA) or you only send a call announcement through the handset (Whisper OHCA), while they are having

another conversation using the handset.
