Abstract
In a telephone network, a platform is coupled to a profile database and a telecommunications relay center. A voice telephone or text telephone caller dials a telephone number for a text telephone subscriber. The platform receives the telephone call and generates voice and text prompts for the caller. The platform senses calling equipment type by listening for the caller's response to the prompts. The platform accesses the profile database and retrieves a prioritized sequence of one or more telephone numbers corresponding to activated locations for the text telephone subscriber. If the caller is a text telephone user, the text telephone call is routed by the platform directly to the text telephone subscriber. If the caller is a voice telephone user, the voice telephone call is relayed through the relay center to the text telephone subscriber.
