ABSTRACT:
In response to a first party (19) being on hold a call that had been established between the first party and a second party (11), the second, holding, party is given an option, by an automated arrangement such as an adjunct processor (21) associated with the first party's local switching system (15), of either remaining on hold or being called back. If the holding party chooses to be called back, the held call is torn down. Later, when the first party attempts to take the call off hold, the automated arrangement instead causes a new call to be placed to the calling telephone number of the torn-down call and to be established between the parties to serve as a substitute for the torn-down call.
