Abstract

A supplementary service, such as H.450 in a specific embodiment, test client is provided. The H.450 test client can send and receive H.450 application protocol data units in any H.225 message. The test client allows for the setting of desired H.450 parameters and allows for the display of the H.450 message itself.

Claims

1. A system, comprising:

an H.323-compatible telecommunications program; and

a test program adapted to receive user-selectable H.450 APDUs, provide said H.450 APDUs to said H.323-compatible telecommunications program, and receive corresponding H.450 APDUs from destination systems.

2. A system in accordance with claim 1, said test program including a graphical user interface (GU I) adapted to allow a user to input predetermined H.225 messages.

3. A system in accordance with claim 2, said GUI adapted to allow a user to fill in H.225 information fields.

4. A system in accordance with claim 3, said GUI adapted to allow a user to input a predetermined network facility extension.

5. A system in accordance with claim 4, said GUI adapted to display said H.225 message in an XML-like format.

6. A system comprising:

an H.450 client; and

a test program adapted to allow a user to specify an H.225 message for sending to other systems.

7. A system according to claim 6, said test program including a graphical user interface (GUI) adapted to allow a user to specify an H.450 APDU and network facility extension.

8. A system in accordance with claim 7, said H.450 APDU viewable as a tree-structured text string.

9. A system in accordance with claim 8, wherein a user can send an H.225 message without an H.450 APDU.

10. A system in accordance with claim 9, said GUI adapted to display said H.225 message in an XML-like format.

11. A method, comprising:

providing an H.323-compatible telecommunications program; and

providing a test program adapted to receive user-selectable H.450 APDUs, provide said H.450 APDUs to said H.323-compatible telecommunications program, and receive corresponding H.450 APDUs from destination systems.

12. A method in accordance with claim 11, said test program including a graphical user interface (GUI) adapted to allow a user to input predetermined H.225 messages.

13. A method in accordance with claim 12, said GUI adapted to allow a user to fill in H.225 information fields.

14. A method in accordance with claim 13, said GUI adapted to allow a user to input a predetermined network facility extension.

15. A method in accordance with claim 14, said GUI adapted to display said H.225 message in an XML-like format.

17. A method according to claim 16, said test program including a graphical user interface (GUI) adapted to allow a user to specify an H.450 APDU and network facility extension.

18. A method in accordance with claim 17, said H.450 APDU viewable as a tree-structured text string.

20. A system in accordance with claim 19, said test program including a graphical user interface (GUI) adapted to allow a user to input a predetermined network facility extension.

16. A method comprising:

providing an H.450 client; and

providing a test program adapted to allow a user to specify an H.225 message for sending to other systems.

19. A system, comprising:

a multimedia telecommunications program; and

a test program adapted to receive user-selectable supplementary service APDUs, provide said supplementary service APDUs to said multimedia telecommunications program, and receive corresponding supplementary service APDUs from destination systems.
