Abstract
A telecommunications system is configured for restarting a telephone call within a telephone network as the call is processed from an originating station progressively through the telephone network. The system determines that the originally dialed number is not associated with optimum processing of the call to a desired final destination. A determination based on call identifier information stored at a telephone network switch or database involves analyzing the call identifier information for caller input or indications of equipment type. A determination can also be made based on messages or data received relating to operational conditions of the switching network; or, data relating to and describing a destination, such as equipment type or services and features available.
