    摘要: A system and method to provide a busy signal to a communication without a terminating network element providing answer supervision and without the originating caller associated with the communication being charged for the communication. A communication that has been forwarded over an integrated services digital network (ISDN) interface connection from a central office to a terminating network element for further routing of the communication to a terminating unit is accepted at the terminating network element and an ISDN interface connection is made, but answer supervision with respect to the communication is not provided. Upon a determination that the terminating unit to which the communication would otherwise be forwarded is busy, the terminating network element provides an ISDN release complete message with respect to the communication to the central office. The ISDN release complete message instructs the central office to play a busy signal to the communication. The terminating network element also releases the ISDN interface connection to the communication. In response to receipt of the ISDN release complete message from the terminating network element, the central office plays a busy signal to the communication.
