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.

Abstract: Communication environment switchover may be provided. A received signal strength level may be determined corresponding to a signal sent from a first device and received at a second device. The received signal strength level may be measured at the second device. In addition, the first device may be re-provisioned. For example, the first device may be re-provisioned to communicate in a second environment if the first device is provisioned to communicate in a first environment and if the received signal strength level is greater than a first threshold value. Furthermore, the first device to be re-provisioned to communicate in the first environment if the first device is provisioned to communicate in the second environment and if the received signal strength level is less than a second threshold value. The second threshold value may be less than the first threshold value.

Abstract: The present invention relates to systems and methods for monitoring and intercepting messages to a voicemail system connected to an AIN or WIN network for screening calls incoming to a landline or wireless telephone. After a call is forwarded to voicemail system, the called party is provided an opportunity to monitor a message as it is spoken into a voicemail system. The called party may intercept the message at any time during delivery of the message to answer the telephone call.
