Abstract
A call between a caller using a telephone device for the deaf (TDD), and requiring one or more types of expertise from a calling assistant, and another person, including a TDD user, is connected by automatically prompting the TDD caller for calling information, automatically identifying the expertise needed, including the language being used, selecting a communication assistant (CA) capable of speaking in the language and other expertise, routing the call to the selected CA, and connecting the call.
