Abstract

The present invention provides systems and methods employing Voice over Internet Protocol (VoIP) technology to provide multi-channel, multi-access voice communication capabilities.

Claims

1. A client/server software based system comprising a plurality of processors and software components, said server software configured to:

a) utilize Voice over Internet Protocol (VoIP) techniques for audio distribution;

b) receive audio information from a plurality of audio sources using said VoIP techniques;

c) send audio information to a plurality of communication devices using said VoIP techniques;

d) provide control information to a control panel interface that permits a client using said control panel interface to manage said audio information;

e) provide control information to a system administration interface that permits a client using said system administration interface to configure the system; and

f) provide control information to a device interface that permits a client using said device interface to interface the system to external audio systems;

wherein said system is a non-blocking system that provides full audio summing allowing;

i) all clients to communicate with any or all other clients in any combination without restriction; and

ii) audio initiated and directed from one client to another to be delivered and heard by the other client without any action required on the part of the receiving client.

2. The system of claim 1, wherein said clients and server deploy on standard, off-the-shelf, personal computer based hardware using existing network infrastructure within either a private local area network or over the public Internet with no geographic constraints.

3. The system of claim 1, wherein the VoIP techniques utilized allow:

a) specification of system and client audio bandwidth to allow user control of audio quality and network bandwidth requirements; and

b) specification of the audio time slice per packet to reduce network bandwidth in favor of increased latency which permits operation over limited bandwidth channels.

4. The system of claim 1, wherein said control panel provides one or more or all of:

a) a plurality of clickable keys to provide on/off control of communication channels with configurable controls for activating talk only, listen only or talk and listen;

b) activation of point-to-point private channel communication between operators;

c) activation of a group call between one or more operators acting as callers and a larger number of listeners;

d) activation of a party line for a group conference between a plurality of callers and listeners;

e) an indication of the log on status of a plurality of operators or listeners;

f) an indication of the active communication status of a channel; and

g) a plurality of different clickable key arrangement options provided to each different operator.

5. The system of claim 1, wherein said system administration interface provides one or both of:

a) the ability to remotely configure all parameters of said system; and

b) the ability to remotely monitor the status all client connections.

6. The system of claim 5, wherein said ability to remotely monitor the status of all client connections includes the ability to monitor audio data rates and packet loss statistics.

7. The system of claim 1, wherein said device interface provides one or more or all of:

a) ability to connect a plurality of external audio devices to the system with no user action required;

b) ability to interface standard analog telephone lines through the use of an off-the-shelf telephone interface device; and

c) ability to sense external logic inputs and activate external logic outputs using input/output hardware.

8. The system of claim 1, wherein the system supports one or more features that are available in professional hardware based intercom solutions, comprising:

a) Channel Isolation (ISO), the ability to create a private two-way point-to-point conversation between clients;

b) Channel Interrupt Fold Back, (IFB), the ability to temporarily interrupt or dim an audio source monitored by a client when another client activates a talk that to that client; and

c) client adjustable audio level control for each selectable communication channel with differentiated handling of audio levels for individual clients and groups.

9. The system of claim 1, using said VoIP techniques, wherein when used with mobile PDAs, SmartPhones, and other off-the-shelf handheld devices connected over WiFi and Cellular data connections, provides enhanced replacement functionality for traditional Two-Way Radios.

10. The system of claim 1, using said VoIP techniques, wherein when deployed on mini-PCs with a sound card connected to standard analog 4-wire phone, provides enhanced replacement functionality of the traditional hard-wired analog 4-wire conference bridge.

11. The system of claim 1, wherein said audio sources include one or more of audio from a wired audio device, audio from a wireless audio device, audio from a telephone, and audio from a two-way radio.

12. The system of claim 1, wherein said control information is provided on a plurality of workstations.

13. The system of claim 12, wherein each of said workstations are configured to dynamically configure said control information.

14. A method of communicating, comprising sending and receiving audio information using a processor and software of a client/server software based system;

said system comprising;

a plurality of processors and software components, said server software configured to;

a) utilize Voice over Internet Protocol (VoIP) techniques for audio distribution;

b) receive audio information from a plurality of audio sources using said VoIP techniques;

c) send audio information to a plurality of communication devices using said VoIP techniques;

d) provide control information to a control panel interface that permits a client using said control panel interface to manage said audio information;

e) provide control information to a system administration interface that permits a client using said system administration interface to configure the system; and

f) provide control information to a device interface that permits a client using said device interface to interface the system to external audio systems;

wherein said system is a non-blocking system that provides full audio summing allowing;

i) all clients to communicate with any or all other clients in any combination without restriction; and

ii) audio initiated and directed from one client to another to be delivered and heard by the other client without any action required on the part of the receiving client.
