Abstract

Captioned telephone are devices intended to provide text captions to persons needing assistance with telephone communications. Captioned telephones provide text by using the services of a relay interposed between the assisted user and the hearing user, the relay providing the captioning for the assisted user. In normal operation, when the assisted user dials a number, the captioned telephone dials the relay which in turn dials the other party to the call. Here a method for operating a captioned telephone is disclosed where the captioned telephone monitors the number being called by the assisted user and, if the user is dialing emergency services (9-1-1 in the U.S.), the call to the relay is terminated and a direct connection to emergency services is initiated. This method is intended to provide the quickest and most error-free connection of the user to emergency services.

Claims

1. In a method of operating a captioned telephone station programmed, when a user dials a number, to normally dial a relay and transfer the called number to the relay, the improvement comprising the steps of:

the captioned telephone station monitoring the number dialed by the user; and

if the user dials number for emergency services, the captioned telephone then acts to not dial the relay but instead dial the emergency services number over the normal local telephone exchange.

2. The method of claim 1 wherein the emergency service number is 9-1-1.

3. The method of claim 1 wherein the captioned telephone when it dial the number for emergency services also turns off the captioning mode.

4. A captioned telephone device programmed to perform the method of claim 1.

5. In a method of operating a captioned telephone station programmed, when a user dials a number, to normally dial a relay and transfer the called number to the relay, the dialing of the relay commencing when the user is still dialing the number to be called, the improvement comprising the steps of:

the captioned telephone station monitoring the number dialed by the user; and

if the user dials number for emergency services, the captioned telephone terminates the call to the relay and instead dials the emergency services number over the normal local telephone exchange.

6. The method of claim 5 wherein the captioned telephone also announces in voice to the emergency services number that an emergency has occurred.
