Abstract

A method, which establishes a voice communications link through the internet community, includes the step of configuring a gateway to use a mapping table to translate input identification data of a called party to a corresponding internet protocol address of another gateway associated with the called party. The method is relatively simple as compared to existing voice over internet protocols.

Claims

1. A method for establishing a voice communications link through the internet community, said method comprising the step of:

(A) configuring a gateway to use a mapping table to translate input identification data of a called party to a corresponding internet protocol (IP) address of another gateway associated with the called party.

2. The method as claimed in claim 1, further comprising the steps of:

prior to step (A), changing the state of the gateway from an idle state to a to_dial state when the gateway detects an off-hook signal;

enabling the gateway to receive the input identification data;

changing the state of the gateway from the to-dial state to a to_invite state when receipt of the input identification data is completed within a predetermined time period;

after step (A), changing the state of the gateway from the to_invite state to a ringback state when the gateway receives a ring signal;

enabling the gateway to transmit an acknowledge signal and changing the state of the gateway from the ringback state to a talking state when the gateway receives an ok signal;

changing the state of the gateway from the talking state to a bye_ok state when the gateway receives a bye signal; and

changing the state of the gateway from the bye_ok state to the idle state when the gateway detects an on-hook signal.

3. The method as claimed in claim 2, further comprising the steps of:

changing the state of the gateway from the to-dial state to a busy state when receipt of the input identification data is not completed within the predetermined time period; and

changing the state of the gateway from the busy state to the idle state when the gateway detects the on-hook signal.

4. The method as claimed in claim 2, further comprising the steps of:

changing the state of the gateway from the to_invite state to a busy state when the gateway does not receive the ring signal; and

changing the state of the gateway from the busy state to the idle state when the gateway detects the on-hook signal.

5. The method as claimed in claim 2, further comprising the step of:

changing the state of the gateway from the to_invite state to the idle state when the gateway detects the on-hook signal.

6. The method as claimed in claim 2, further comprising the steps of:

changing the state of the gateway from the ringback state to a to_cancel state when the gateway detects the on-hook signal; and

changing the state of the gateway from the to_cancel state to the idle state when the gateway receives the ok signal.

7. The method as claimed in claim 2, further comprising the steps of:

changing the state of the gateway from the talking state to the to_bye state when the gateway detects the on-hook signal; and

changing the state of the gateway from the to_bye state to the idle state when the gateway receives the ok signal.

8. The method as claimed in claim 2, further comprising the steps of:

changing the state of the gateway from the idle state to a ringing state when the gateway receives an invite signal;

enabling the gateway to transmit the ok signal and changing the state of the gateway from the ringing state to a to_answer state when the gateway detects the off-hook signal;

changing the state of the gateway from the to_answer state to a talking state when the gateway receives the acknowledge signal;

changing the state of the gateway from the talking state to a to_bye state when the gateway detects the on-hook signal; and

changing the state of the gateway from the to_bye state to the idle state when the gateway receives the ok signal.

9. The method as claimed in claim 8, further comprising the step of:

changing the state of the gateway from the ringing state to the idle state when the gateway receives a cancel signal.

10. The method as claimed in claim 8, further comprising the steps of:

changing the state of the gateway from the to_answer state to a busy state when the gateway receives a cancel signal; and

changing the state of the gateway from the busy state to the idle state when the gateway detects the on-hook signal.

11. The method as claimed in claim 1, wherein the gateway conforms to the transmission control protocol (TCP).

12. The method as claimed in claim 1, wherein the gateway conforms to the real-time transport protocol (RTP).

13. The method as claimed in claim 1, wherein the input identification data includes an identification number.

14. The method as claimed in claim 1, wherein the input identification data includes a speed dialing code number.

15. The method as claimed in claim 1, further comprising the step of manually updating gateway settings through one of an interactive voice response (IVR), a user interface, and a web-based service.

16. The method as claimed in claim 1, further comprising the step of configuring the gateway to report the IP address to a dynamic domain name server.
