  • Patent number: 6292551
    Abstract: The call reestablishment system functions to provide the user with the ability to replace an existing communication connection with another equivalent communication connection in an automated manner that does not disrupt the existing call and to also provide the user with the ability to create a replacement communication connection using a different common carrier as the billing source. The call reestablishment system is activated when a party on an existing communication connection generates feature activation control signals indicative of the desire to access the call reestablishment system. The serving communication system, in response to receipt of the feature activation control signals, enables the requesting party to input data indicative of the nature of the call reestablishment that is required.
