Abstract

A system and method for establishing a conference between a first user and a second user. The first user has an audio stream. The second user has an audio stream. The conference has an audio stream. A temporary conference is created. The audio stream of the conference is directed to the sidebar conference. The audio stream of the first user is directed to the temporary conference and the audio stream of the second user is directed to the temporary conference. The audio stream of first user and the audio stream of the second user are only audible to the first user and the second user.

Claims

1. A method of sidebar conferencing, the method comprising:

establishing a call conference between a first user, the first user having an audio stream, and a second user, the second user having an audio stream, the call conference having an audio stream;

creating a temporary call conference by transmitting a SIP INVITE message to a call conference server requesting a temporary call conference, wherein the SIP INVITE message indicates that the audio from the call conference should be a talk only participant in the temporary call conference;

directing the audio stream of the call conference to the temporary call conference by transmitting a first SIP RE-INVITE message to the call conference server indicating that the server should receive audio from the call conference; and

directing the audio stream of the first user to the temporary call conference and directing the audio stream of the second user to the temporary call conference by transmitting second and third SIP RE-INVITE messages to the first and second user, respectively, wherein the audio stream of the first user and the audio stream of the second user are only audible to the first user and the second user.

2. The method of claim 1 further comprising prompting the first user for information indicating the identity of the second user.

3. The method of claim 2 wherein prompting the user includes presenting a menu to the user.

4. The method of claim 2 further comprising receiving and processing voice commands from the first user.

5. The method of claim 1 further comprising determining whether the second user desires to enter the sidebar with the first user.

6. A device for conducting a sidebar conference between a first user and a second user, the device comprising:

means for establishing a call conference between a first user, the first user having an audio stream, and a second user, the second user having an audio stream, the call conference having an audio stream;

means for creating a temporary call conference by transmitting a SIP INVITE message to a call conference server requesting a temporary call conference, wherein the SIP INVITE message indicates that the audio from the call conference should be a talk only participant in the temporary call conference;

means for directing the audio stream of the conference to the temporary call conference by transmitting a first SIP RE-INVITE message to the call conference server indicating that the server should receive audio from the call conference; and

means for directing the audio stream of the first user to the temporary conference and directing the audio stream of the second user to the temporary conference by transmitting second and third SIP RE-INVITE messages to the first and second user, respectively, wherein the audio stream of the first user and the audio stream of the second user are only audible to the first user and the second user.

7. The system of claim 6 further comprising means for prompting the first user for information indicating the identity of the second user.

8. The method of claim 7 wherein the means for prompting the user includes means for presenting a menu to the user.

9. The method of claim 7 further comprising means for receiving and processing voice commands from the first user.

10. The method of claim 6 further comprising means for determining whether the second user desires to enter the sidebar with the first user.

11. A method for establishing a sidebar conference between a first user and a second user, within a on-going conference, the on-going conference having an audio stream, the first user having an audio stream, the second user having an audio stream, the method comprising the steps of:

directing the audio stream of the conference to a temporary conference by transmitting a first SIP RE-INVITE message to the call conference server indicating that the server should receive audio from the call conference; and

directing the audio stream of the first user to the temporary conference and directing the audio of the second user to the temporary conference by transmitting second and third SIP RE-INVITE messages to the first and second user, respectively, wherein the audio stream of the first user and the audio stream of the second user are only audible to the first user and the second user.

12. A computer program for establishing a sidebar conference, the program comprising:

first code for establishing a conference between a first user, the first user having an audio stream, and a second user, the second user having an audio stream, the conference having an audio stream;

second code for creating a temporary conference by generating a SIP INVITE message to a call conference server requesting a temporary call conference, wherein the SIP INVITE message indicates that the audio from the call conference should be a talk only participant in the temporary call conference;

third code for directing the audio stream of the conference to the temporary conference by transmitting a first SIP RE-INVITE message to the call conference server indicating that the server should receive audio from the call conference; and

fourth code for directing the audio stream of the first user to the temporary conference and directing the audio stream of the second user to the temporary conference by transmitting second and third SIP RE-INVITE messages to the first and second user, respectively wherein the audio stream of first user and the audio stream of the second user are only audible to the first user and the second user.

13. A computer readable medium having stored therein instructions for causing a processing unit to execute the following method:

establishing a conference between a first user, the first user having an audio stream, and a second user, the second user having an audio stream, the conference having an audio stream;

creating a temporary conference by generating a SIP INVITE message to a call conference server requesting a temporary call conference, wherein the SIP INVITE message indicates that the audio from the call conference should be a talk only participant in the temporary call conference;

directing the audio stream of the conference to the temporary conference by transmitting a first SIP RE-INVITE message to the call conference server indicating flat the server should receive audio from the call conference; and

directing the audio stream of the first user to the temporary conference and directing the audio stream of the second user to the temporary conference by transmitting second and third SIP RE-INVITE messages to the first and second user, respectively, wherein the audio stream of first user and the audio stream of the second user are only audible to the first user and the second user.
