Abstract

A process of transferring a message transferred by a TTY call from a calling party to a called party comprising the following steps: (a) receiving the TTY call in a port adapted to receive the TTY call; (b) recognizing the TTY call as conforming to TTY standards and translating the TTY call to ASCII; (c) initiating a request for the calling party provide identification information to identify the called party and to leave a message and converting the request to conform to the TTY standards to create a converted response, and sending the converted response to the calling party, (d) receiving the identification information to identify the called party and the message, converting the identification information and the message to ASCII to create a converted message; identifying a voice mail box accessible by the called party with the identification information in a voice mail system; (e) converting the message into an audio message; and storing the audio message in the voice mail box. An integrated text based system comprises a telephone network, a private branch exchange, a voice mail system, and a text server. The telephone network receives a TTY call from a calling party using a TTY device to a called party. The TTY call is modem translatable and has information disclosing a format of a calling device being used to initiate the TTY call.

Claims

1. A process of automatically transferring a message transferred by a TTY call from a calling party to a called party, comprising:

(a) receiving said TTY call in a port adapted to receive said TTY call;

(b) recognizing said TTY call as conforming to TTY standards and translating said TTY call to ASCII;

(c) initiating a request for said calling party to provide identification information to identify said called party and to leave a message and converting said request to conform to said TTY standards to create a converted response, and sending said converted response to said calling party;

(d) receiving said identification information to identify said called party and said message, converting said identification information and said message to ASCII to create a converted message;

(e) identifying a voice mail box accessible by said called party with said identification information in a voice mail system;

(f) converting said converted message into an audio message;

(g) leaving said audio message in said voice mail box in said voice mail system; and

(h) notifying said calling party that said audio message has been received by said voice mail box in said voice mail system.

2. The process of claim 1, further comprising the following step after step (d)

(e1) checking a database of individuals able to receive said TTY call to ensure that said called party is in said database of individuals able to receive said TTY call.

3. The process of claim 2, wherein said database of individuals able to receive said TTY call is comprised of a list of individuals having access to a text server.

4. The process of claim 1, wherein said identification information is selected from a group consisting of said called party'"'"'s first name, said called party'"'"'s employee number, said called party'"'"'s social security number, said called party'"'"'s computer address, said called party'"'"'s mailbox number, said called party'"'"'s log in name, said called party'"'"'s last name, said called party'"'"'s full name, and said called party'"'"'s individual telephone number.

5. A process, comprising:

(a) receiving a modem translatable call from a calling party to a receiving party at a system port, said modem translatable call having information disclosing a format of a calling device being used to initiate said modem translatable call, said format and said calling device adapted to be used by an individual selected from a group consisting of a deaf individual, hearing impaired individual, or a speech impaired individual;

(b) identifying said format of said calling device;

(c) adjusting said system port to receive said modem translatable call;

(d) translating said modem translatable call to a text format to create a text call; and

(e) converting said text call into an audio message;

(f) leaving said audio message in a voice mail box accessible by said receiving party; and

(g) notifying said receiving party to alert said receiving party that said audio message is in said voice mail box.

6. The process of claim 5, wherein said modem translatable call is selected from a group consisting of a voice call, a text message, a TTY call, fax message, and a TTD call.

7. The process of claim 5, wherein said modem translatable call is received from a telephone system via standardized telephone service.

8. The process of claim 7, wherein said system port is internal to said telephone system.

9. The process of claim 5, wherein said text format is ASCII.

10. An integrated text based system, comprising:

(a) a telephone network adapted to receive a TTY call from a calling party using a TTY telephone device to a called party, said TTY call being modem translatable, said TTY call having information disclosing a format of said TTY telephone device being used to initiate said TTY call;

(b) a private branch exchange in communication with said telephone network and adapted to receive said TTY call via said telephone network, said private branch exchange in communication with a telephone, said called party having access to said telephone;

(c) a voice mail system in communication with said private branch exchange, said voice mail system in communication with said telephone via said private branch exchange; and

,

(d) a text server in communication with said private branch exchange via a modem so that said text server is able to receive said TTY call, said modem in communication with said text server, said modem able to receive and identify said TTY call as conforming to TTY standards and able to convert said TTY call to a text based format to create an audio based call, said modem also able to receive a response to said TTY call, convert said response to said TTY call to conform to said TTY standards, and transmit said response to said TTY call once converted, said text server also in communication with said voice mail system, said text server converts said text-based format to an audio format to create an audio call and sends said audio call to said voice mail system, so that said voice mail system can store said audio call in a mail box location to which said called party has access.

11. The integrated text based system of claim 10, wherein said text server initiates said response to said TTY call to said calling party to provide identification information to identify said called party, said text server checks a first database of individuals able to receive said TTY call to determine whether said called party is in said first database and is able to receive said TTY call.

12. The integrated text based system of claim 11, wherein said text server determines whether said called party is in said first database, and if said text server determines that said called party is in said first database of individuals able to receive said TTY call, then said text server presents said calling party with a greeting and prompts said calling party to send electronic mail to said called party, sends said electronic mail to said called party.

13. The integrated text based system of claim 11, wherein said identification information is selected from a group consisting of said called party'"'"'s first name, said called party'"'"'s employee number, said called party'"'"'s social security number, said called party'"'"'s computer address, said called party'"'"'s mailbox number, said called party'"'"'s log in name, said called party'"'"'s last name, said called party'"'"'s full name, and said called party'"'"'s individual telephone number.

14. The integrated text based system of claim 11, wherein said voice mail system has a voice mail database of all parties having access to said voice mail system and if said called party is not in said first database, then said text server instructs said voice mail system to check said voice mail database to determine whether said called party is in said voice mail database and is able to receive said TTY call.
