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. Only KX-T7400 series telephone users can send Whisper OHCA.
• This feature is not available for an ISDN telephone user.
