<p>A call screening method allows calls made to the subscriber to be screened while the subscriber uses another communications medium. An enhanced services platform (ESP) receives a call from a caller using a public telephone number for the subscriber (202). The ESP accesses a database storing a public telephone number and a private packet-based address for subscribers and retrieves a private packet-based address of the subscriber (206, 208). An introductory message prompts the caller to leave a message (210). The ESP uses the private packet-based address to establish an audio connection via the communication medium and notifies the subscriber o the call (212, 214). If the subscriber answers the call a communication path is provided between the caller and subscriber so the subscriber may hear the caller leave the message without the caller knowing the subscribe is listening (216). The ESP connects the caller and subscriber for two-way communication upon authorization of the subscriber (218).</p> |
