Abstract

A conference phone system includes personal headsets and a base unit. The personal headsets individually capture audios of local participants on a conference call (“local audios”) and transmit the local audios in separate and identifiable channels to the base unit. The base unit receives the local audios and transmits the local audios in separate and identifiable audio streams over a network to a network client. For a remote participant on the conference call, the network client reproduces the local audios and indicates one or more participants who are presently speaking. The network client can also virtualize the local audios so that the remote participant can distinguish the participants by their relative positions, whether virtual or actual. The network client uses the audio source identification information of various participants to enable conference features to mute, enhance, or hold private sidebar conversations.

Claims

1. A method for a base unit to hold a conference call for local participants, comprising:

individually capturing audios of the local participants (“

local audios”

); and

transmitting the local audios in separate and identifiable audio streams over a network to a network client.

2. The method of claim 1, wherein said individually capturing audios of the local participants comprising wirelessly receiving the local audios in separate and identifiable channels from wireless headsets used by the local participants.

3. The method of claim 2, further comprising:

receiving an identifiable audio stream of a remote participant of the conference call (“

remote audio”

) over the network from the network client; and

reproducing the remote audio to the local participants, wherein said reproducing is selected from the group consisting of reproducing the remote audio with a speaker and wirelessly transmitting the remote audio to the wireless headsets used by the local participants.

4. The method of claim 1, further comprising:

receiving an audio of a telephonic participant on the conference call (“

POTS audio”

) over a telephone network from a POT (plain old telephone);

transmitting the POTS audio in an identifiable audio stream over the network to the network client;

receiving an identifiable audio stream of a remote participant of the conference call (“

remote audio”

) over the network from the network client; and

transmitting the local audio and the remote audio over the telephone network to the POT.

5. A method for a network client to hold a conference call for a remote participant, comprising:

representing participants of the conference call on a monitor;

receiving audios of participants in separate and identifiable audio streams over a network;

monitoring volumes of the audios;

when a volume of one audio exceeds a threshold, indicating one corresponding participant as presently speaking on the monitor; and

reproducing the audios to the remote participant.

6. The method of claim 5, wherein said reproducing the audios to the remote participant comprises virtualizing the audios on stereo speakers to distinguish between the participants.

7. The method of claim 5, further comprising only reproducing an audio from one participant in response to an instruction from the remote participant to solo said one participant.

8. The method of claim 5, further comprising enhancing an audio from one participant in response to an instruction from the remote participant, said enhancing being selected from the group consisting of increasing the volume of the audio from said one participant and decreasing the volume of the audios from the participants except said one participant.

9. The method of claim 5, further comprising stop reproducing an audio from one participant in response to an instruction from the remote participant to mute said one participant.

10. The method of claim 5, further comprising transmitting an audio of the remote participant (“

remote audio”

) in an identifiable audio stream over the network to a base unit.

11. The method of claim 5, further comprising, in response to an instruction for a sidebar conversation with one participant:

transmitting an identity of said one local participant to participate in the sidebar conversation over the network; and

reproducing only an audio from said one participant.

12. The method of claim 5, wherein at least one of the participants is selected from the group consisting of another remote participant at another network client, a local participant at a base unit connected to the network client over the network, and a telephonic participant connected to the base unit.

13. A conference phone system, comprising:

headsets individually (a) capturing audios of local participants on a conference call (“

local audio”

) and (b) transmitting the local audio in a separate and identifiable channel; and

a base unit (a) receiving local audios from the headsets, and (b) transmitting the local audios in separate and identifiable audio streams over a network to a network client.

14. The system of claim 13, wherein:

the headsets each comprises (a) a microphone for capturing the local audio of a local participant, and (b) a radio transmitter for transmitting the local audio to the base unit in the separate and identifiable channel; and

the base unit comprises;

(a) a radio receiver for receiving the local audios from the headsets, and

(b) a VoIP (Voice-over-Internet Protocol) interface for;

(1) transmitting the local audios in separate and identifiable audio streams over the network to the network client; and

(2) receiving an identifiable audio stream of a remote participant on the conference call (“

remote audio”

) over the network from the network client.

15. The system of claim 14, wherein:

the base unit further comprises a radio transmitter for transmitting the remote audio to the headsets; and

the headsets each further comprises (c) a radio receiver for receiving the remote audio from the base unit, and (d) a speaker for reproducing the remote audio.

16. The system of claim 15, wherein the base unit further comprises a speaker for reproducing the remote audio.

17. The system of claim 14, wherein the VoIP interface further receives, over the network from the network client, an identifiable audio stream of a remote participant on the conference call (“

remote audio”

) and an identity of a selected local participant to receive the remote audio in a sidebar conversation, the base unit further comprising a radio transmitter that transmits the remote audio only to a wireless headset of the selected local participant in response to receiving the identity of the selected local participant.

18. The system of claim 14, wherein:

the base unit further comprises (c) a POTS (plain old telephone system) interface for receiving an audio of a telephonic participant on the conference call (“

POTS audio”

) over a telephone network from a POT (plain old telephone), the VoIP interface further transmitting the POTS audio in a separate and identifiable audio stream over the network to the network client;

the base unit further comprising a radio transmitter for transmitting the POTS audio to the wireless headsets; and

the POTS interface further transmits the local audios and the remote audio to the POT.

19. A conference phone system, comprising a network client for a remote participant on a conference call, the network client (a) representing participants on the conference call on a monitor, (b) receiving, over the network, audios of the participants in separate and identifiable audio streams, (c) indicating one or more participants who are presently speaking on the monitor when volumes of their audio streams exceed a threshold, and (d) reproducing the audios to the remote participant.

20. The system of claim 19, wherein the network client further includes a stereo headset and said reproducing comprises virtualizing the audios to the stereo headset to distinguish between the participants.

21. The system of claim 19, wherein the network client only reproduces an audio from one participant in response to an instruction from the remote participant to solo said one participant.

22. The system of claim 19, wherein in response to an instruction from the remote participant to enhance an audio of one participant, the network client increases a volume of the audio from said one participant or decreases volumes of the audios from the participants except said one participant.
