First Claim
1. In a telecommunications network including a terminating network element connected to a service switching point, a method for providing automatic recall-related information of an automatic recall service stored in said service switching point to said terminating network element, said method comprising the steps of:
- placing said automatic recall-related information into at least one field of a message;
routing said message from said service switching point to said terminating network element; and
causing said terminating network element to retrieve said automatic recall-related information from said field of said message, whereby said terminating network element may use said automatic recall-related information to provide enhanced services.

Abstract
A method and system for providing an open interface, or access to, information that is stored in a called party switch in relation to an automatic recall telecommunications service. Automatic recall service allows a customer to dial a special feature code and receive an enunciation of the directory number of the last incoming caller Typically, automatic recall-related information is stored in the called party switch and is not accessible to external network elements that may provide enhanced services with this information. This automatic recall-related information may include information such as the directory number of the last incoming caller, the time stamp of the last incoming call, and/or the privacy indicator of the last incoming call. The method includes placing the automatic recall-related information into at least one field of a telecommunications message, such as an ISUP message. The message is routed from the called party switch to the terminating network element that is to provide an enhanced service. The terminating network element may then retrieve the automatic recall-related information from the fields of the message. The terminating network element may then use the automatic recall-related information to provide enhanced services.
