ABSTRACT:
A subscriber to a remote call forwarding feature on a wire-line telephone line associated with a PBX (101) or central office (402) can enable that feature by dialing feature code from his cellular phone (103, 403). The subscriber dials a feature code from his cellular phone, which feature code is received by the cellular phone's Mobile Switching Center (MSC) (105, 405) and forwarded to a Service Control Point (SCP) (106, 406). The SCP recognizes the feature code as a request to invoke the remote call forwarding feature on the subscriber's wire-line telephone so that calls directed to that wire-line telephone are forwarded to the cellular phone. Receipt of that feature code by the SCP, together with the cellular phone's Electronic Serial Number (ESN) and Mobile Identification Number (MIN) identifies the subscriber and the feature to be invoked for that subscriber. By performing a database (108, 408) lookup associated with that ESN and MIN, information is retrieved relating to what PBX or switch should be contacted to invoke the feature, how and where to contact that PBX or switch, and what specifically must be sent to that PBX or switch to invoke the feature on the subscriber's telephone line.
