摘要： A method and system are disclosed for automated call back of a first telephone station that has been placed on hold by a second telephone station in an advanced intelligent network. The system comprises a service switching point connected to the first telephone station, a service node adapted to connect the second telephone station with the first telephone station when the second telephone station becomes available, and a service control point containing a database identifying the service node as adapted to connect the second and first telephone stations. The method includes the following steps: at the service switching point forwarding a request to the service control point to identify one of the plurality of service nodes to handle an automated call back from the second station to the first station; searching the database at the service control point for one of the plurality of service nodes to handle the automated call back to the first station from the second station; identifying to the service switching point, one of the plurality of service nodes to handle the automated call back from the second station to the first station; forwarding to the service node a request for automated call back from the second station to the first station; and upon receiving a signal from the second station at the service node, connecting the second station and the first station.

摘要： A system and method for providing an on-hold call with a selectable continuous tone source using a service node, comprising a service switching point of a central office connected to a service logic program provisioned on a service node. Using the capabilities of the service node, the service logic program plays a continuous tone through a permanent trunk line connecting the service node to the service switching point. When the service switching point puts a call on hold, the service switching point connects the call through the permanent trunk line to the service logic program that is playing the continuous tone. As a result, the caller hears the continuous tone while the service switching point has the call on hold. In addition, the present invention provides a dual tone multifrequency administrative interface on the service logic program of the service node, which enables a customer to dial the interface, enter a passcode for access, and then choose between a variety of tone types such as a dial tone, a busy signal, a normal ring tone, a reorder signal (fast busy signal), a continuous busy signal, and a continuous ring tone.
