A call processing method, system and communication device for providing call authorization features. Generally described, the present application relates to authorizing communications between devices during call setup time. In one illustrative embodiment, communications within a telephone network configured within a private branch exchange or carrier are filtered using an authorizing device. The authorizing device can be activated using different procedures including, but not limited to, feature access codes and pin numbers. When a call is received from a calling device, the telephone network can reserve a line for the call to the intended restricted device. The authorizing device can thereafter be alerted about the call. A user of the authorizing device can answer the call or direct the telephone network to block the call, connect the call with the restricted device through the reserved line, or forward the call to a third device. |
