Abstract:
1. A sequential number ringing system connecting a calling party to a first alternative number associated with a main number dialed by the calling party, the system comprising: a Service Control Point (SCP) with a sequential ring application (SRA) resident thereon; and a first call list associated with the main number and containing the first alternative number; and a second call list containing at least one second alternative number; a Service Switching Point (SSP) provisioned with a trigger list associating the main number with a T_Busy trigger and with a T_No_Answer trigger; wherein the SSP connects the calling party to the main number in response to the main number being answered; wherein the SSP is further operative to fire the T_Busy trigger in response to a determination that a call to the main number cannot be connected because the main number is busy; wherein the SSP is further operative to fire the T_No_Answer trigger in response to a determination that a call to the main number cannot be connected because the main number is not answered within a predefined ring number; wherein the SRA is operative to cause the SSP to connect the calling party to the first alternative number, in response to a determination that the T_Busy trigger has been fired; wherein the SCP is communicatively coupled to a plurality of SSPs; and wherein the SRA is operative to cause the SSP to connect the calling party to the first alternative number, in response to a determination that the T_No_Answer trigger has been fired; wherein the first call list is used under a first set of conditions and the second call list is used under a second set of conditions, the second set of conditions different from the first set of conditions.
