When attempting to call a busy extension (ringing or having a conversation), an extension user 
can send call waiting indication to the busy extension (Call Waiting). The notification receiving 
method depends on the called extension’s personal setting and the telephone type:

•

Each extension user can choose to receive Call Waiting tone, OHCA, Whisper OHCA, or 
none of these. 

•

OHCA and Whisper OHCA are enabled or disabled by the COS of the calling extension.

•

OHCA and Whisper OHCA do not work for some telephone types. In such cases, the Call 
Waiting tone will be sent to the called extension.

•

The notification receiving methods (Call Waiting tone, OHCA, and Whisper OHCA) are 
available when the called extension is having a conversation with other party. If not, the 
calling extension will be kept waiting until the called extension becomes available to 
receive the notification. Even while waiting, the calling extension will hear a ringback tone.

•

If none of these notification receiving methods, Call Waiting tone, OHCA, or Whisper 
OHCA is set at the called party, the caller will hear reorder tone.

Sends the Call Waiting tone to the busy 
extension. 

Talk with the busy extension using the built-in 
speaker and microphone of the called extension 
while the existing call is made using the handset.

Give a message to the busy extension through 
the handset.
