Abstract

A multimedia telecommunications network provides telephone service which may involve one or more of audio, video, and data communications. In one example of the invention, the multimedia telecommunications network contains a virtual meeting services complex which provides multimedia telecommunications service to subscribers of the network. Multimedia telephone calls can be completed automatically by the virtual meeting services complex in a manner similar to that now used to complete conventional audio telephone calls. The multimedia telecommunications network containing this virtual meeting services complex is able to connect together users having diverse equipment and is able to handle integrated and nonintegrated network access mechanisms.

7. The method of claim 6, wherein the calling party is prompted to provide information about a called party.

8. The method of claim 6, in which the prompting step comprises prompting the calling party for authentication information.

35. The method of claim 2, further comprising:

adapting the virtual meeting room for use by subscribers with different telecommunications capabilities; and

allowing the same or different subscribers to initiate or continue the multimedia call.

9. A method of creating a multimedia call between at least two subscribers, comprising the steps of:

receiving a directory number of at least one called party from a calling party to initiate the multimedia call;

determining whether the calling party and at least one of the at least one called party are subscribers to a virtual meeting services complex offered by the multimedia telecommunications network;

determining a telecommunications capability of the subscribers;

providing an interface to allow subscribers with different telecommunications capabilities to effectuate the multimedia call; and

connecting the subscribers to a node in the multimedia telecommunications network.

10. The method of claim 9, further comprising the step of:

creating a connection having predefined characteristics between the calling party and each called party that is determined to be a subscriber.

11. The method of claim 10, in which the connection comprises one or more of a plurality of multiple media connections.

12. The method of claim 11, in which the multiple media are selected from the group consisting of audio, video, and data.

13. The method of claim 10, in which the predefined characteristics comprise a bandwidth associated with the connection.

14. The method of claim 10, in which the predefined characteristics are default characteristics determined when the calling party subscribe to the virtual meeting services complex.

15. The method of claim 10, in which the predefined characteristics are determined as a result of prompts made to the calling party at a multimedia call setup.

16. A method of effectuating a multimedia call between a calling party and at least one called party in a multimedia telecommunications network, the calling party and the at least one called party being subscribers to the virtual meeting services complex, comprising the steps of:

automatically identifying a telecommunications capability of a calling party and at least one of the at least one called party to communicate in one or more of a plurality of media in response to a call placed by the calling party to the at least one called party, the plurality of media including audio, video and data;

providing an interface to allow subscribers with different telecommunications capabilities to effectuate the multimedia call; and

connecting the subscribers in one or more of the identified media.

17. The method of claim 16, in which the identifying step comprises the step of detecting an ANI of the calling party and a directory number of the at least one of the at least one called party.

18. The method of claim 17, in which the identifying step comprises the step of addressing a database with the ANI and the directory number and retrieving information about a telecommunications capability of the calling party and the at least one of the at least one called party stored in a database for the ANI and directory number.

19. The method of claim 16, in which the identifying step comprises the step of determining whether there is a mismatch between the communication characteristics of the calling party and the called party.

20. The method of claim 19, in which the mismatch comprises different telecommunication capabilities between the calling party and each called party.
