Abstract
A call between a caller using a telephone device for the deaf (TDD) and another including a TDD user is connected by automatically prompting the TDD caller for calling information, parsing the received calling information to determine a forward number, and routing the call to one of a number of communication assistants. One embodiment involves storing the forward number before routing the call so the communications assistant can press a single button to connect the call. Another embodiment entails connecting the call automatically routing the call to the communications assistant.
