Abstract

In a telephone conferencing system, a digital communication network such as the Internet is used to establish and control the telephone connections between multiple conferees with the telephone network being the means of exchanging verbal information. Each conferee may have a computer connected to the digital network, and each has an independent telephone instrument connected to the public switched telephone network. An in-charge conferee utilizes his computer containing appropriate software to initiate the conference and to control the participation of the conferees. The in-charge conferee sends digital control signals to a switch interface controlling a telephone switch as a gateway to the telephone network using SS7 control signals. These SS7 control signals include the commands by which the conferee telephones are rung up, brought on line, or dropped from the conference.

Claims

1. A system for establishing a telephonic connection for a conference among a plurality of conferees, the system comprising:

a digital computing device configured to control telephonic connections over a public Internet Protocol (IP) network; and

a switch interface in communication with the digital computing device over the public IP network and further in communication with a dial up communication network, wherein the digital computing device is configured to transmit digital control signals to the switch interface over the public IP network,

wherein the switch interface is configured to transmit telephonic control signals to the dial up communication network in response to the digital control signals to establish at least one telephonic connection for a conference among the plurality of conferees.

2. The system of claim 1, wherein the digital control signals include a telephone number associated with a conferee telephone device, and wherein the telephonic control signals cause the dial up communication network to dial up the conferee telephone device based upon the telephone number.

3. The system of claim 1, wherein the dial up communication network is an SS7 compatible dial up communication network, and wherein the telephonic control signals are SS7 telephonic control signals.

4. The system of claim 1, wherein the digital computing device transmits additional digital control signals to the switch interface to add a conferee to the conference, and

wherein the switch interface transmits additional telephonic control signals to the dial up communication network in response to the additional digital control signals to establish a telephonic connection for the added conferee.

5. The system of claim 1, wherein, the digital computing device transmits additional digital control signals to the switch interface to remove a conferee from the conference, and

wherein the switch interface transmits additional telephonic control signals to the dial up communication network in response to the additional digital control signals to disconnect a telephonic connection for the removed conferee.

6. The system of claim 1, wherein the public IP network is the Internet.

7. The system of claim 1, wherein the digital computing device is located at a conferee station.

8. The system of claim 1, wherein the digital computing device is a personal computer.

9. A method for establishing a telephonic connection for a conference among a plurality of conferees, the method comprising:

receiving digital control signals from a digital computing device over a public Internet Protocol (IP) network; and

transmitting telephonic control signals to a dial up communication network in response to the digital control signals to establish at least one telephonic connection for a conference among the plurality of conferees.

10. The method of claim 9, wherein the digital control signals include a telephone number associated with a conferee telephone device, and wherein the telephonic control signals cause the dial up communication network to dial up the conferee telephone device based upon the telephone number.

11. The method of claim 9, wherein the dial up communication network is an SS7 compatible dial up communication network, and wherein the telephonic control signals are SS7 telephonic control signals.

12. The method of claim 9, further comprising:

receiving additional digital control signals from the digital computing device over the public IP network to add a conferee to the conference; and

in response to receiving the additional digital control signals, transmitting additional telephonic control signals to the dial up communication network to establish a telephonic connection for the added conferee.

13. The method of claim 9, further comprising:

receiving additional digital control signals from the digital computing device over the public IP network in order to remove a conferee from the conference; and

in response to receiving the additional digital control signals, transmitting additional telephonic control signals to disconnect a telephonic connection for the removed conferee.

14. The method of claim 9, wherein the public IP network is the Internet.

15. The method of claim 9, wherein the digital computing device is located at a conferee station.

16. The method of claim 9, wherein the digital computing device is a personal computer.

17. A system for establishing a telephonic connection for a conference among a plurality of conferees, the system comprising:

a digital computing device configured to control telephonic connections over an Internet Protocol (IP) network; and

a switch interface in communication with the digital computing device over the IP network and further in communication with a dial up communication network, wherein the digital computing device is configured to transmit digital control signals to the switch interface over the IP network,

wherein the switch interface is configured to transmit telephonic control signals to the dial up communication network in response to the digital control signals to establish at least one telephonic connection for a conference among the plurality of conferees, and

wherein the digital computing device is further configured to monitor the at least one telephonic connection over the IP network.

18. The system of claim 17, wherein the digital computing device is further configured to transmit additional digital control signals to the switch interface to remove a conferee from the conference, and

wherein the switch interface is further configured to transmit additional telephonic control signals to the dial up communication network in response to the additional digital control signals to disconnect a telephonic connection for the removed conferee.

19. The system of claim 17, wherein the digital computing device is located at a conferee station.

20. The system of claim 17, wherein the digital computing device is a personal computer.
