Abstract
Systems, methods, and devices that support and automatically enable text (TTY) mode or voice mode for any incoming and outgoing calls are disclosed. In accordance with embodiments of the present invention, the ability to automatically enable or disable TTY mode for any calls to and from a telematics system is provided. For incoming calls, calling phone numbers with TTY devices are automatically recognized based on a comparison to numbers in a TTY table, and in instances of a match, the TTY mode is automatically enabled. For outgoing calls, the calls may be automatically connected to a pre-configured TTY service number. The automatic operation in either TTY mode or voice mode may be based on additional configurations and statuses. In some embodiments of the present invention, the systems, methods, and devices may be used in conjunction with a vehicle.
