First Claim
Patent Images
1. A telecommunications system for processing a call from a calling communication station for a called communication station, the telecommunications system comprising:
- an end office switch configured to ring the called communication station with the call and determine blocking status for the call, the end office switch being further configured to play an announcement to the calling communication station offering a messaging service if the call is unblocked, the end office switch being further configured to disconnect the call from the called communication station if the messaging service is selected, a service control point (SCP) configured to receive a query for further routing instructions for the call, the SCP configured to return a response message if the call passes additional screening criteria;
a platform configured to provide the messaging service to the calling communication station; and
a service switching point (SSP) configured to receive the response message from the SCP and connect the calling communication station with the platform to provide the messaging service.

Abstract
A method for providing a messaging service in a telecommunication system (900) includes providing a calling party with an option to leave a voice message (1010). If the calling party accepts the option, determining screening criteria for the called communication station (1018). In response to the screening criteria, the call is selectively completed to a messaging service (172).

10. A telecommunications system capable of providing a messaging service for a call from a calling communication station to a called communication station, the telecommunications system comprising:
-
an end office switch associated with the called communication station, the end office switch including software for determining blocking status for the call if the call is not answered, software for playing an announcement to the calling communication station offering the messaging service if the call is unblocked, and software for detecting a service selection input entered at the calling communication station;
a service control point (SCP) including software for determining if the call passes additional screening criteria when the call has been routed to the SCP if the messaging service is selected, and software for routing the call to a service node for prompting and recording a message of the called communication station in response to passing the additional screening criteria. - View Dependent Claims (11, 12)
