Abstract

A call between a caller using a telephone device for the deaf (TDD) and another including a TDD user is connected by automatically prompting the TDD caller for calling information, parsing the received calling information to determine a forward number, and routing the call to one of a number of communication assistants. One embodiment involves storing the forward number before routing the call so the communications assistant can press a single button to connect the call. Another embodiment entails connecting the call automatically routing the call to the communications assistant.

Claims

1. The method of relaying a call between a telephone device for the deaf (TDD) and other users, comprising:

automatically prompting a TDD caller with a generic signal which is absent of demands for specific calling information and permits natural language. response;

parsing the received natural language response for calling information to determine a forward number; and

routing the call to one of a number of communication assistants.

2. The method as in claim 1, wherein the step of automatically prompting a TDD caller includes receiving the TDD call with a modem in a modem pool.

3. The method as in claim 1, wherein the step of routing the call to one of a number of communication assistants includes automatically prompting the caller to indicate that the call is being placed.

4. The method as in claim 1, wherein the step of parsing includes looking for a forward number of seven, ten, or eleven, or international digits.

5. The method as in claim 4, wherein the step of parsing includes accepting all valid combinations and spacing of digits.

6. The method as in claim 1, wherein the step of parsing includes looking for alternate billing by credit in one of credit card, collect, person-to-person, and third-party charging number.

7. The method as in claim 6, wherein the step of parsing includes looking for a credit card number.

8. The method as in claim 1, wherein the step of parsing includes looking for the number of a calling party.

9. The method as in claim 1, wherein the step of parsing includes looking for a go ahead signal.

10. The method as in claim 1, wherein the step of parsing includes entering data on a billing record with at least one of a forwarding number, a billing number, a credit card number, and a calling number.

11. The method as in claim 1, wherein the step of routing the call to one of a number of communication assistants includes automatically setting a forward number to have the communication assistant dial the forward number with a single key stroke.

12. The method as in claim 1, wherein the step of routing the call to one of a number of communication assistants includes automatically dialing the forward number and prompting the communication assistant to handle the call.

13. An apparatus for relaying a call between a telephone device for the deaf (TDD) and other users, comprising:

means for automatically prompting a TDD caller with a generic signal which is absent of demands for specific calling information and permits natural language response;

means for parsing received natural language response for calling information to determine a forward number;

means for routing the call at the modem means to one of a number of communication assistants for automatic dialing by the assistant.

14. An apparatus as in claim 13, wherein the means for automatically prompting a TDD caller includes modem means for receiving the TDD call and having a modem in a modem pool.

15. An apparatus as in claim 13, wherein the means for routing the forward number to one of a number of communication assistants includes means for automatically prompting the caller to indicate that the call is being placed.

16. An apparatus as in claim 13, wherein the means for parsing includes means for looking for a forward number of seven, ten, or eleven, or international digits.

17. An apparatus as in claim 14, wherein the means for parsing includes means for accepting all valid combinations and spacing of digits.

18. An apparatus as in claim 13, wherein the means for parsing includes means for looking for alternate billing by credit in one of credit card, collect, person-to-person, and third-party charging number.

19. An apparatus as in claim 16, wherein the means for parsing includes means for looking for a credit card number.

20. An apparatus as in claim 13, wherein the means for parsing includes means for looking for the number of a calling party.

21. An apparatus as in claim 13, wherein the means for parsing includes means for looking for a go ahead signal.

22. An apparatus as in claim 13, wherein the means for parsing includes means for entering data on a billing record with at least one of a forwarding number, a billing number, a credit card number, and a calling number.

23. An apparatus as in claim 13, wherein the means for routing the call to one of a number of communication assistants includes means for automatically setting a forward number to have the communication assistant dial the forward number with a single key stroke.

24. An apparatus as in claim 13, wherein the means for routing the call to one of a number of communication assistants includes means for automatically dialing the forward number and prompting the communication assistant to handle the call.
