The system automatically activates the Attendant Call Waiting feature whenever an attendant originates or extends a call to a single-line telephone user who is on an existing call. When the system activates Attendant Call Waiting, the:
Attendant hears a call waiting ringback tone
Telephone user hears a call waiting tone
Calling party does not hear a tone
The attendant can place a call in progress on hold. After the attendant answers the call on hold, the attendant can use the Hold button to return to the held call. The attendant can alternate between the two calls.
For example, assume that extension 123, a single-line telephone, is busy. An attendant extends an incoming call to extension 123. The attendant hears the call waiting ringback tone, which indicates that Attendant Call Waiting is activated. The attendant can:
Announce the call-waiting condition to the calling party
Cancel the Attendant Call Waiting feature, and ask the calling party to call again later
Release the caller, or place the call on hold at the console
Releasing an attendant-originated call drops the call completely.
The user at extension 123 hears a call-waiting tone, and knows that a call is waiting. The user can:
If the user does not answer the waiting call before a preassigned time interval, the system returns the call to the attendant.
