Abstract

A method and system are disclosed for providing call screening in conjunction with a variety of network-based call services. An exemplary method for providing a called party at a called party station with call screening includes: (a) forwarding a call to the called party station (CPS) to a voice mailbox so that a caller can leave a message for the called party; (b) initiating a simplex call to the CPS; and (c) bridging the call forwarded to the voice mailbox and the simplex call to the CPS so that the called party can hear the caller leaving a message for the CPS; (d) initiating a duplex call to the CPS in response to signaling received from the CPS; and (e) bridging the call forwarded to the voice mailbox and the duplex call so that the caller and the called party are in communication with one another. In one embodiment of the present invention, the step of initiating a simplex call includes the step of delivering a distinctive ring to the CPS indicating that the caller is leaving a message for the CPS. In another embodiment of the present invention, the step of initiating a simplex call includes the step of transmitting a call waiting indicator to the CPS. In yet another embodiment of the invention, the step of initiating a simplex call includes the step of transmitting a signal to the CPS indicating that the calling party station will pay for cellular charges associated with the call.
