Automatically sequentially ringing alternative telephone numbers
First Claim
1. A sequential number ringing system connecting a calling party to a first alternative number associated with a main number, comprising:
- a Service Control Point (SCP) with a sequential ring application (SRA) resident thereon; and
a plurality of call lists, each of the plurality of call lists containing a plurality of alternative numbers;
a first call list of the plurality of call lists associated with the main number and, the first call list containing the first alternative number; and
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 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 select the first call list from amongst the plurality of call lists based on an identity of the calling party and 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; and
wherein the SRA is operative to select the first call list from amongst the plurality of call lists based on an identity of the calling party and 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.

Abstract
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, but cannot reach the main number, a Service Switching Point (SSP) fires a trigger. One trigger is a T_No_Answer trigger, which is fired in response to a call to the main number that is not answered within a predefined number of rings. Another trigger is a T_Busy trigger that is fired in response to a call to the main number that is made when the main number is busy. Each trigger causes the SCP to access the call list and to cause the SSP to ring an alternative telephone number associated with the main telephone number. If this attempt to reach the called party also fails, then the SSP again fires the trigger and an attempt is made to connect the calling party to the next number on the call list. If the call list is exhausted before the calling party is connected to a number on the called party'"'"'s call list, then a message can be played to the calling party. Alternatively, the calling party may be connected to a voice mailbox associated with the called party or may receive a busy tone.
