11. A system for enabling subscribers to a voicemail service to screen telephone calls forwarded to a voicemail box, the system comprising:
-
a service switching point for routing the telephone calls to and from a subscriber'"'"'s telephone, wherein the service switching point comprises an AIN trigger; a service control point for directing the routing of the telephone calls received at a service switching point in response to a query generated by the AIN trigger; a service node for receiving an incoming telephone call routed from the service switching point; and an access table, wherein the service node retrieves a voicemail access number associated with the subscriber'"'"'s telephone line from the access table, wherein when the subscriber'"'"'s telephone operates in a wireless network, and when the service node receives the incoming telephone call, the service node places a first outgoing call to the subscriber'"'"'s telephone and delays placing a second outgoing call to a voicemail box to account for a longer call set-up time in the wireless network, the delayed second outgoing call ensuring the subscriber may screen an entire message recorded by a voicemail system, and the service node allocates a three-way conference bridge between the incoming call and the second outgoing call to the voicemail box when the second outgoing call to the voicemail box is answered, and connects the first outgoing call to the subscriber'"'"'s telephone via a connect_oneway_path without any further subscriber intervention when once the call to the subscriber'"'"'s telephone is answered. - View Dependent Claims (12)
