Abstract

Methods and systems for providing an improved communications channel for telephone conference initiation and management are provided. Messages for initiating and managing a telephone conference are exchanged between a client computer and a gateway computer utilizing XML formatted messages transmitted over an instant messaging compatible protocol. The gateway computer converts the messages to web services requests and communicates with telephone conference network hardware utilizing the web services-based request. Status indicators from the telephone conference equipment is converted from web services requests to XML by the gateway and transmitted back to the client computer via the instant messaging protocol.

The method of claim 4, wherein extracting from the instant message the data for establishing the telephone conference comprises extracting the extensible markup language data and wherein creating a web services request based on the data comprises created a web services request based on the extensible markup language data.

6. The method of claim 5, wherein executing the web services request in order to establish the telephone conference comprises transmitting the web services request to a conference web service, and wherein the conference web service is operative to cause a conference bridge to initiate the telephone conference according to the extensible markup language data.

7. The method of claim 1, further comprising:

converting the indication that a telephone call has been placed to an instant message at the telephone conference gateway, the instant message including data indicating that the telephone call is in a ringing state;

transmitting the instant message to the instant messaging server computer;

forwarding the instant message from the instant messaging server computer to the client computer; and

receiving the instant message at the client computer, extracting from the instant message the data indicating that the call is in a ringing state, and displaying data at the client computer indicating that the call is in a ringing state.

8. The method of claim 7, further comprising:

receiving at the telephone conference gateway an indication that the telephone call has been answered by one of the participants, the indication being received as a web services request;

converting the indication to an instant message at the telephone conference gateway, the instant message including data indicating that the telephone call has been answered;

transmitting the instant message to the instant messaging server computer;

forwarding the instant message from the instant messaging server computer to the client computer; and

receiving the instant message at the client computer, extracting from the instant message the data indicating that the call has been answered, and displaying data at the client computer indicating that the call has been answered.

9. The method of claim 8, further comprising:

receiving at the client computer a request to disconnect one of the participants from the telephone conference;

in response to the request, transmitting an instant message including data for requesting that the participant be disconnected from the telephone conference;

receiving the instant message at the instant messaging server computer, and forwarding the instant message to the telephone conference gateway computer;

receiving the instant message at the telephone conference gateway computer, extracting from the instant message the data requesting that the participant be disconnected, creating a web services request based on the data, and executing the web services request in order to disconnect the participant from the phone conference.

10. The method of claim 8, further comprising:

receiving at the telephone conference gateway an indication that a participant has disconnected from the telephone conference, the indication being received as a web services request;

converting the indication to an instant message at the telephone conference gateway, the instant message including data indicating that the participant has disconnected from the telephone conference;

transmitting the instant message to the instant messaging server computer;

forwarding the instant message from the instant messaging server computer to the client computer; and

receiving the instant message at the client computer, extracting from the instant message the data indicating that the participant has disconnected from the telephone conference, and displaying data at the client computer indicating that the participant has disconnected.

11. A system for providing and utilizing an improved communications channel for establishing and maintaining a telephone conference, the system comprising:

a client application program operative to;

transmit an instant message to an instant messaging server computer, the instant message including data requesting that a telephone conference between two or more participants be established, and

display data extracted from an instant message received at the client computer indicating that a placed telephone call associated with the requested telephone conference is in a ringing state;

a gateway application program operative to;

receive the instant message from the instant messaging server computer,

extract from the instant message the data requesting that a telephone conference be established,

create a web services request based on the data,

transmit the web services request to a network device capable of establishing the telephone conference,
