Abstract

A method is presented comprising transmitting, from an application computer communicably connected to a gatekeeper which is connected to a data network, packetized messages indicative of telephone calls in progress at an endpoint of the data network, or indicative of such endpoint, and transmitting, from the gatekeeper to the application computer, packetized messages indicative of a variety of information contained in the telephone calls so as to process such information for a variety of applications. Apparatus to implement the method is also presented.

Claims

1. A method comprising:

transmitting, from an application computer connected to a data network to a call processing device connected to said data network, over said data network, packetized messages indicative of telephone calls in progress at an endpoint of said data network, or indicative of said endpoint, said application computer being located separately from said endpoint; and

transmitting, from said call processing device to said application computer over said data network, packetized messages indicative of the length of said telephone calls.

2. The method of claim 1, wherein said packetized messages include the originating IP address of the call.

3. The method of claim 1, wherein said packetized messages include the words exchanged in the call.

4. A method comprising:

transmitting, from an application computer connected to a data network to a call processing device connected to said data network, over said data network, packetized messages indicative of telephone calls in progress at an endpoint of said data network, or indicative of said endpoint, said application computer being located separately from said endpoint; and

transmitting, from said call processing device to said application computer over said data network, packetized messages indicative of the information in said telephone calls.

5. The method of claim 4, wherein said information includes the originating IP address of the call.

6. The method of claim 4, wherein said information includes the words exchanged in the call.

7. A method comprising:

transmitting, from an application computer communicably connected to a call processing device which is connected to a data network, packetized messages indicative of telephone calls in progress at an endpoint of said data network, or indicative of said endpoint; and

transmitting, from said call processing device to said application computer, packetized messages indicative of the information in said telephone calls.

8. The method of claim 7, wherein said information includes the originating IP address of the call.

9. The method of claim 7, wherein said information includes the words exchanged in the call.
