Captioned telephone service

1. A method of operating a captioned telephone call in which an assisted user is connected by a captioned telephone device that is connected both by a first line to a remote user and a second line to a relay providing captioning for a conversation, the method comprising the steps of:

detecting the start of an incoming call on the first line prior to the call being answered;

upon detecting the start of an incoming call on the first line and prior to the call being answered, without any assisted user input subsequent to the start of the call, the captioned telephone device automatically establishing a communication link to the relay on the second line to initiate captioning service set up;

subsequent to the assisted user answering the incoming call, the captioned telephone device passing spoken words received on the first line to the second line; and

receiving text captions of the spoken words back from the relay at the captioned telephone device on the second line, wherein words received on the first line include words spoken by the assisted user and words spoken by the remote user, the step of passing spoken words on the first line to the second line including cancelling the words spoken by the assisted user and only passing words spoken by the remote user to the second line.

2. A method of operating a captioned telephone call in which an assisted user is connected by a captioned telephone device that is connected both by a first line to a remote user and a second line to a relay providing captioning for a conversation, the method comprising the steps of:

when a call is received at the captioned telephone device on the first line, without any assisted user input subsequent to the start of the call and prior to the call being answered, the captioned telephone device automatically calling the relay on the second line to establish an interconnection to the relay;

linking the call to an assigned call assistant after a predetermined condition is satisfied;

the captioned telephone device passing spoken words received on the first line to the second line; and

the relay then providing text captions of the spoken words back to the captioned telephone device on the second line, wherein words received on the first line include words spoken by the assisted user and words spoken by the remote user, the step of passing spoken words on the first line to the second line including cancelling the words spoken by the assisted user and only passing words spoken by the remote user to the second line.

3. A method of facilitating a captioned telephone call using a captioned telephone device used by an assisted user, the captioned telephone device connectable by a first line to a remote user and a second line to a relay providing captioning for a conversation, wherein the captioned telephone device includes at least one caption control feature for selecting automated captioning upon reception of an incoming call, the method comprising the steps of:

upon detecting an incoming call on the first line, without any assisted user input subsequent to the start of the call, the captioned telephone device checking a status of the caption control feature and, when a captioning default is selected, automatically calling the relay on the second line to initiate captioning service set up;

at the relay, a call assistant assigned to the call to generate text captions corresponding to words spoken by the remote user;

the captioned telephone device passing spoken words received from the remote user on the first line to the second line; and

the relay providing text captions of the spoken words back to the captioned telephone device on the second line, wherein words received on the first line include words spoken by the assisted user and words spoken by the remote user, the step of passing spoken words on the first line to the second line including cancelling the words spoken by the assisted user and only passing words spoken by the remote user to the second line.

4. The method of claim 3 wherein the step of assigning a call assistant to the call includes assigning a call assistant to the call after the link to the relay is established.

5. The method of claim 4 wherein the step of assigning a call assistant to the call includes detecting that one of the incoming call is answered by the assisted user and the outgoing call is answered by the remote user and assigning a call assistant after the call is answered.

6. The method of claim 1 wherein text captions are generated by a call assistant at the relay, the method further including the step of, subsequent to establishing the communication link with the relay, assigning a call assistant to the incoming call.

7. The method of claim 6 wherein the step of assigning a call assistant includes assigning the call assistant to the incoming call subsequent to answering of the incoming call.

8. The method of claim 7 wherein the incoming call is answered by an assisted user manually answering the incoming call.

9. The method of claim 1 wherein the captioned telephone device includes at least one caption control feature for selecting automated captioning upon reception of an incoming call, the step of automatically establishing a communication link to the relay on the second line to initiate captioning service set up includes, the captioned telephone device checking a status of the caption control feature and, when a captioning default is selected, automatically calling the relay on the second line to initiate captioning service set up.

10. The method of claim 2 wherein the predetermined condition includes the call being answered.

11. The method of claim 2 wherein the captioned telephone device includes at least one caption control feature for selecting default captioning, the predetermined condition including selection of default captioning.

12. The method of claim 3 further including the steps of, upon detection of a start of an outgoing call, checking the status of the caption control feature and, when the caption control feature is set to a default caption status, automatically calling the relay on the second line to initiate the captioning service.

13. The method of claim 1 further including the steps of, upon detecting the start of an outgoing call on the first line and prior to the call being answered, without any assisted user input subsequent to the start of the call, the captioned telephone device automatically establishing a communication link to the relay on the second line to initiate captioning service set up.

14. The method of claim 13 further including the steps of, subsequent to the remote user answering the incoming call, the captioned telephone device passing spoken words received on the first line to the relay on the second line.

15. The method of claim 14 wherein text captions are generated by a call assistant at the relay, the method further including the step of, subsequent to establishing the communication link with the relay, assigning a call assistant to the call.

16. The method of claim 15 wherein the step of assigning a call assistant includes assigning the call assistant to the call subsequent to answering of the call.

17. The method of claim 6 wherein the assisted user's device includes a caption control feature, the method further including automatically assigning a call assistant to a call after the call is answered only if the caption control feature is set to default to a caption state.
