• If “BSS” is not displayed or you hear a reorder tone, this feature is not set at the other party’s phone.
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.
• This feature is not available for an ISDN telephone user.
