  • Patent number: 6721406
    Abstract: A system for obtaining location data of calling parties for telephone calls provides location data for display by a called device. Through reception of the name, telephone number, or other calling party identifier as is done through the conventional caller ID service, the called device formulates a query to a database containing location data for calling parties. Existing advanced intelligent network infrastructure may be used to provide caller ID data to the called device, and the called device uses this caller ID data to formulate the query to the database. Additionally, the called device may have access to multiple databases containing location data and may detect an appropriate database to query based upon analysis of the caller ID data that has been received.

  • Patent number: 6683940
    Abstract: The invention contemplates a device, system, and method of transferring a voice mail message. The inventive method includes receiving a voice mail message directed to a telephone number, correlating the telephone number to at least one email address, and forwarding the voice mail message to the email address. The method further may include converting the voice mail message to an electronic data file, like a text file and/or audio file, for example. Also, the electronic data file may provide a name of a party initiating the voice mail message, a telephone number of a party initiating the voice mail message, a time and a date of the voice mail message, and/or a duration of the voice mail message, for example. The inventive method may further include storing the voice mail message on a computer-readable medium associated with the email address.

  • Patent number: 6674840
    Abstract: Methods and systems are disclosed for automatically verifying the correct provisioning of recent subscribers to provisioned services and identifying subscribers for whom services were not correctly provisioned. The automatic verification and identification system comprises a service switching point, a service control point and an automatic provisioning verification testing device. The testing device is adapted to place a call to the subscriber's telephone directory number through the service switching point. The service switching point is adapted to suspend calls directed to a service control point and to send information concerning calling and called parties to the service control point. The service control point is adapted to querying a database of subscription information and replacing the calling party information with information to be verified. The service control point then directs the service switching point to call the incoming telephone line of the testing device.

  • Publication number: 20030100319
    Abstract: A method of delivering a call to a called party's device. The method includes receiving a call directed to a wireline device and validating that a telephone number of the wireline device is associated with a telephone number of a wireless device. The method also includes transmitting a message to the wireless device, delivering the call to the wireline device when a return message is not received from the wireless device, and determining a location of the wireless device when a return message is received from the wireless device. The method further includes comparing the location of the wireless device with a location of the wireline device, delivering the call to the wireless device when the location of the wireless device is not within a predefined vicinity of the location of the wireline device, and delivering the call to the wireline device when the location of the wireless device is within a predefined vicinity of the location of the wireline device.

  • Publication number: 20030002645
    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.

  • Publication number: 20020118812
    Abstract: A system for providing location ID services for telephone calls transfers location data describing the location of the calling device to the called device. Rather than or in addition to providing the name and telephone number as is done through the conventional caller ID service, the location of the calling device is displayed by the called device including the zip code, the longitude and latitude planar coordinates, or the street address. Existing advanced intelligent network infrastructure may be adapted to provide the location ID service, such as by providing location data queries from a signal switching point to a signal control point. The signal control point has access to a CNAM database containing location ID data fields in addition to conventional caller ID data.

  • Patent number: 6427001
    Abstract: Notification of 911 telephone calls is provided to a telephone numbers listed on a pre-provided list of the telephone numbers without intrusion on the existing 911 infrastructure using the out-of-band SS7 signaling infrastructure. A link monitoring system (LMS) monitors SS7 messages to determine whether a 911 telephone call has been made. When the LMS determines that a 911 telephone call has been made, it sends a message containing calling party number information to a notification device. Using the telephone numbers provided on the notification list, the notification device notifies others that the 911 telephone call has been made.

  • Publication number: 20020085687
    Abstract: Methods and systems are disclosed for audibly announcing information associated with a calling party in an advanced intelligent network comprising a service switching point, a service control point and a services node. The service switching point is adapted to suspend calls directed to an audio caller identification service and to forward information concerning the calling and called parties to the service control point. The service control point is adapted to direct the call to a selected services node. The services node sends a query to retrieve information concerning the calling party from the service control point. If necessary, other service control points may be queried for the information. While the aforementioned processing is occurring, the calling party continues to hear a ringing signal. When the aforementioned information is retrieved, the service directs a second call to the called party.
