Abstract

A method and a system to establish an Internet telephone call from a terminal device. The method may comprise displaying a graphical user interface of a web telephone on the terminal device. In response to displaying the graphical user interface, a script interpreter of a web browser executing on the terminal device is activated, with the script interpreter establishing a signaling channel with a communication server, and registering the web telephone with the communication server.

Claims

1. A system to establish an Internet telephone call from a terminal device, the system comprising:

a web telephone script invokable from an interface displayable by a web browser, and

a script interpreter of the web browser, the script interpreter being under instructions of the web telephone script to;

display a representation of a web telephone on a graphical user interface of the terminal device; and

establish a signaling channel with a communication server after the representation of the web telephone is displayed on the graphical user interface of the terminal device, in order to register the web telephone with the communication server.

2. The system of claim 1, wherein the script interpreter is to interface the web telephone script with a microphone and a speaker of the terminal device.

3. The system of claim 2, wherein the script interpreter is to receive a call request entered via the graphical user interface and wherein the script interpreter is to transmit the call request to the communication server.

4. The system of claim 3, wherein the script interpreter is to establish, after transmitting the call request to the communication server, a media channel with the communication server.

5. The system of claim 4, wherein the script interpreter is to receive a ring-tone from the communication server, prior to the communication server making a connection with a telephone associated with the dialed number.

6. A communication server to establish an Internet telephone call from a terminal device, the server comprising a signaling protocol handler to receive a signaling request from a script interpreter of a web browser, the web browser being under instructions of a script of a web telephone.

7. The communication server of claim 6, wherein the script of the web telephone is reference via a hyperlink to the web page or embedded in a web page.

8. The communication server of claim 7, wherein the signaling protocol handler is to establish the signaling channel, in response to receiving the signaling channel request.

9. The communication server of claim 8, wherein the signaling protocol handler is to receive a call request from the web telephone, the call request being entered via a graphical user interface of the web telephone.

10. The communication server of claim 9, further comprising a media processor to establish a media channel with the script interpreter of the web telephone, in response to the signaling protocol handler receiving the call request.

11. The communication server of claim 10, wherein the media processor is to transmit a ring-tone to the web telephone.

12. The communication server of claim 11, wherein the signaling protocol handler is to determine, based on the received call request, a signaling protocol to establish a connection with a telephone identified by the call request.

13. The communication server of claim 12, wherein the signaling protocol handler is to transmit a call request to a gateway using the determined signaling protocol, thereby to establish a telephone call between the web telephone and the telephone.

14. A method of establishing an Internet telephone call from a terminal device, the method comprising:

displaying a graphical user interface of a web telephone on the terminal device; and

in response to displaying the graphical user interface, activating a script interpreter of a web browser executing on the terminal device;

the script interpreter establishing a signaling channel with a communication server, and registering the web telephone with the communication server.

15. The method of claim 14, further comprising receiving a call request via the graphical user interface and transmitting the call request to the communication server.

16. The method of claim 15, further comprising the script interpreter establishing, in response to transmitting the call request to the communication server, a media channel with the communication server.

17. The method of claim 16, further comprising receiving a ring-tone from the communication server, prior to a connection being made with a telephone associated with the dialed number.

28. A machine-readable medium embodying a set of instructions to perform the method of claim 14.

18. A method of establishing an Internet telephone call from a terminal device, the method comprising:

receiving, at a communication server, a signaling channel request, the signaling channel request being received from a script interpreter of a web browser, under instructions of a web telephone script invokable from an interface displayable by the web browser.

19. The method of claim 18, further comprising establishing the signaling channel, in response to receiving the signaling channel request.

20. The method of claim 19, further comprising receiving a call request via a graphical user interface and establishing a media channel with the script interpreter, in response to receiving the call request.

21. The method of claim 20, further comprising transmitting a ring-tone from the communication server to the web telephone.

22. The method of claim 21, further comprising determining, at a signaling protocol handler and in response to the received call request, a signaling protocol to establish a connection with a telephone identified by the call request.

23. The method of claim 22, further comprising transmitting a call request to a gateway using the determined signaling protocol, in order to establish a telephone call between the web telephone and the telephone identified by the call request.

29. A machine-readable medium embodying a set of instructions to perform the method of claim 18.

24. A communication server to establish an Internet telephone call from a terminal device, the server comprising first means for receiving a signaling request from a script interpreter of a web browser, the web browser being under instructions of a script of a web telephone.

25. The communication server of claim 24, wherein the first means is to establish the signaling channel, in response to receiving the signaling channel request.

26. The communication server of claim 25, wherein the first means is to receive a call request from the web telephone, the call request being entered via a graphical user interface of the web telephone.

27. The communication server of claim 26, further comprising second means for establishing a media channel with the script interpreter of the web telephone, in response to the first means receiving the call request.
