A Service Control Point (SCP) has a call list associated with the main telephone number of a called party. When a calling party attempts to contact the called party by calling the main number, a Service Switching Point (SSP) or a Mobile Switching Center (MSC) fires a trigger. The trigger causes the SCP to access the call list and to cause the SSP/MSC to simultaneously ring the main (called) telephone number and at least one alternative telephone number associated with the main telephone number. A simultaneous ring service subscriber can remotely access the SCP to modify a call list, to add or delete a call list and to select an active call list. When a subscriber has multiple call lists, the subscriber can set account parameters to automatically select the active call list, based on various call factors, such as call time and calling party.
