Abstract

One embodiment of the present invention is a gateway call routing system used to route calls, wherein the gateway connects a PSTN and the Internet. The call routing system includes a first computer connection module for connecting to a computer terminal, such as an Internet voice terminal, of a calling party, and a first phone connection module for connecting to a phone terminal of the calling party. In addition, the call routing system includes a second computer connection module for connecting to a computer terminal of a called party, and a second phone connection module for connecting to a phone terminal of the called party. Further, the call routing system includes a voice tuning module which sets voice tuning to a phone-to-phone mode if the terminal of the calling party is a phone and the terminal of the called party is also a phone, to a computer-to-phone mode if the terminal of the calling party is a computer and the terminal of the called party is a phone, to a phone-to-computer mode if the terminal of the calling party is a phone and the terminal of the called party is a computer, and to a computer-to-computer mode if the terminal of the calling party is a computer and the terminal of the called party is also a computer.

Claims

1. An integrated call routing system used to perform voice tuning on calls, comprising:

a first computer connection module used to receive calls placed using an Internet voice terminal;

a first phone connection module used to receive calls placed by a first phone unit intended to be fixed to a specific switch at a central switching location; and

at least a first voice tuning module configured to automatically perform a first type of voice tuning for calls received by the first computer connection module whose destination information indicates that the destination is a phone unit, wherein the voice tuning module is configured to automatically perform a second type of voice tuning for calls received by the first computer connection module whose destination information indicates that the destination is another Internet voice terminal, wherein the voice tuning module is configured to automatically perform a third type of voice tuning for calls received by the first phone connection module whose destination information indicates that the destination is a phone unit, and wherein the voice tuning module is configured to automatically perform a fourth type of voice tuning for calls received by the first phone connection module whose destination information indicates that the destination is an Internet voice terminal.

2. The integrated call routing system as defined in claim 1, wherein the Internet voice terminal is an H.323 terminal, including a computer having a microphone and a speaker.

3. The integrated call routing system as defined in claim 1, wherein the voice tuning module performs at least echo cancellation and packet size adjustment.

4. The integrated call routing system as defined in claim 1, wherein the voice tuning module performs at least volume adjustment and jitter buffer adjustment.

5. The integrated call routing system as defined in claim 1, wherein the call routing system is included in a Voice over Internet Protocol (VoIP) gateway.

6. The integrated call routing system as defined in claim 1, wherein the integrated routing system is configured to route call packets over the Internet.

7. The integrated call routing system as defined in claim 1, wherein the integrated routing system is coupled to a Public Switched Telephone Network (PSTN) to receive calls from phone units.

8. A method of performing voice tuning for calls placed over a telephony network, comprising:

receiving call information for a call, the call information including destination information, from a first terminal;

determining what type of terminal the first terminal is;

examining the destination information to determine if the destination terminal is a phone or an Internet voice terminal;

performing computer-to-computer voice tuning for the call at least partly in response to determining that the first terminal is an Internet voice terminal and that the destination terminal is an Internet voice terminal;

performing phone-to-computer voice tuning for the call at least partly in response to determining that the first terminal is a phone and that the destination terminal is an Internet voice terminal;

performing computer-to-phone voice tuning for the call at least partly in response to determining that the first terminal is an Internet voice terminal and that the destination terminal is a phone; and

performing phone-to-phone voice tuning for the call at least partly in response to determining that the first terminal is a phone and that the destination terminal is a phone.

9. The method as defined in claim 8, further comprising connecting the call to the destination terminal via the Internet.

10. The method as defined in claim 8, further comprising receiving a second call from a second phone via a Public Switched Telephone Network (PSTN).

11. The method as defined in claim 8, further comprising receiving a second call from a second phone using a Voice over Internet Protocol (VoIP) gateway phone connection module.

12. The method as defined in claim 8, further comprising receiving a second call from a second Internet voice terminal using a Voice over Internet Protocol (VoIP) gateway computer connection module.

13. The method as defined in claim 8, wherein the voice tuning further comprises adjusting a volume of the call.

14. The method as defined in claim 8, wherein the voice tuning further comprises performing echo cancellation on the call.

15. The method as defined in claim 8, wherein the voice tuning further comprises adjusting a jitter buffer.

16. The method as defined in claim 8, wherein the voice tuning further comprises adjusting a packet size of a call packet.

17. An integrated IP call routing system comprising:

means for connecting a computer terminal of a calling party;

means for connecting a phone terminal of the calling party;

means for connecting a computer terminal of a called party;

means for connecting a phone terminal of the called party; and

voice tuning means for setting voice tuning to a phone-phone mode if the terminal of the calling party is a phone and the terminal of the called party is also a phone, to a computer-phone mode if the terminal of the calling party is a computer and the terminal of the called party is a phone, to a phone-computer mode if the terminal of the calling party is a phone and the terminal of the called party is a computer, and to a computer-computer mode if the terminal of the calling party is a computer and the terminal of the called party is also a computer.
