Abstract

A conferencing system provides for the simultaneous processing of audio and document information during a conference call. An audio conferencing bridge includes the functionality to provide an audio connection between attendees who have dialed into the bridge through either the Public Switch Telephone Network or over a data network using IP telephony. Each of the meeting attendees has access to a user interface with a connection to a data network. On each user interface is a web browser which includes a specially designed plug-in for converting documents from traditional word processing or database formats to HTML. A list is compiled in the conferencing bridge which includes the names and IP addresses for each of the attendees. Once the plug-in has converted the documents to HTML format, a series of icons are incorporated into the documents which provide for the transmission of this information to the other parties. At the time a party wishes to broadcast this information to the others, it is first transmitted via an e-mail to the conferencing bridge which accesses a list of attendees. Using PUSH technology, the documents are transmitted via the data network to the web browsers of all the other attendees. The specially designed plug-in allows each conference attendee to broadcast documents to all other attendees.

Claims

1. A method of holding an electronic conference comprising the steps of:

a plurality of conference attendees establishing a connection with a conference bridge through a data network;

compiling a list of Internet Protocol (IP) addresses of the plurality of conference attendees;

identifying a conference leader connected to the conference bridge through a user interface;

establishing an audio connection between the conference leader and the conference attendees over the audio connection with the conference bridge;

upon the selection of the conference leader, receiving at an email processor incorporated in the conference bridge at least one email from the conference leader which includes at least one electronic document converted to HTML format; and

accessing the IP addresses of the conference attendees from the compiled list and recreating, in response to the at least one email from the conference leader, the HTML document on a web browser associated with each of the IP addresses of the plurality of conference attendees using PUSH technology.

2. The method of claim 1 wherein the audio connection is through IP telephony over the data network.

3. The method of claim 1 wherein at least one electronic document converted to HTML format includes icons which the conference leader may activate to transmit an entire one of the at least one electronic document converted to HTML format or just a single page thereof.

4. The method of claim 1 wherein any of conference attendees may become the conference leader and convert and email electronic documents to the email processor so that they may be recreated on the web browsers of the other conference attendees.

5. The method of claim 1 wherein the IP addresses for the conference attendees may be entered through touch tone signals.

6. The method of claim 1 wherein the at least one electronic document converted to HTML format are queued and provided to the conference attendees as they establish contact with the conference bridge.

7. The method of claim 1 wherein the connection is established with a plurality of the conference bridges.

8. A conferencing system comprising:

an audio conferencing processor connectable to a public switched telephone network which provides for establishment of audio communications between a plurality of remotely located system users, wherein one of the remotely located system users is identified as a conference leader, the audio conferencing processor compiling a list of Internet Protocol (IP) addresses of the plurality of remotely located system users; and

an email processor connectable to a data network which is configured to receive at least one email which includes at least one HTML document from the conference leader and to recreate the at least one HTML document on a web browser at the IP address for each of the plurality of remotely located system users using PUSH technology.

9. The system of claim 8 wherein the audio communications are established through IP telephony over the data network.

10. The system of claim 8 wherein the data network is the Internet.

11. The system of claim 8 wherein the system includes a processing module to receive and process at least one reply e-mail from at least one of the plurality of remotely located system users.

12. The system of claim 11 wherein the processing module stores all the reply e-mail received and recreates any documents included in the reply e-mail on the web browser at the IP addresses for each of the plurality of remotely located system users using PUSH technology.

13. The system of claim 11 wherein a plurality of the audio conferencing processors and email processors are included for the establishment of audio communications and the transmission of documents to the plurality of remotely located system users.
