Abstract:
A system and method for communicating a pre-stored emergency message from a TTY to a PSAP may include, in response to receiving an emergency call signal, accessing a pre-stored emergency message stored in a memory. A PSAP may be dialed. In one embodiment, the PSAP may be dialed by the user dialing 911 or the TTY may automatically dial 911 in response to the user selecting a hard or soft-button associated with communicating an emergency message to a PSAP. The pre-stored emergency message may be communicated to a PSAP using a TTY communications protocol. A TTY compatible device utilized by a PSAP operator may be configured to provide the PSAP operator with pre-stored messages available for selection and communication to the emergency caller. By providing pre-stored messages on TTY devices, emergency communications between users of the TTY devices may be expedited, thereby potentially saving lives.
