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.

Automatically sequentially ringing alternative telephone numbers

An audio calling name and calling number delivery method is disclosed. When a call is made from a calling party telephone to a called party telephone, a message is sent from an originating service switching point (SSP) associated with the calling party telephone to a terminating mobile switching center (MSC) associated with the wireless called party telephone. Typically, the message comprises the directory number of the calling party telephone. A wireless trigger is tripped at the terminating MSC and, in response, a query is sent to a service control point (SCP). A home location register (HLR) associated with the wireless telephone is queried to determine whether the wireless telephone is available. If the wireless telephone is available, then a name and a number associated with the calling party telephone is forwarded to a service node. The service node places a call to the wireless telephone and an audio annunciation of the name and the number is played to the called party.
