Apparatus and method for computer controlled call processing applications in packet switched telephone networks

A method comprising:

• transmitting, from an application computer connected to a data network to a gatekeeper connected to said data network, over said data network, packetized messages indicative of a telephone call or 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 gatekeeper to said application computer over said data network, packetized messages indicative of the information associated with, or relevant to, said telephone calls.

A method 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 said data network, or indicative of said endpoint;
• and
• transmitting, from said gatekeeper to said application computer, packetized messages indicative of the information associated with or contained in said telephone calls.

A method comprising:

• transmitting, from an application computer connected to a data network to a call controller 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 controller to said application computer over said data network, packetized messages indicative of the length of said telephone calls.

A method comprising:

• transmitting, from an application computer connected to a data network to a call controller 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 controller to said application computer over said data network, packetized messages indicative of the information associated with or contained in said telephone calls.

A method comprising:

• transmitting, from an application computer communicably connected to a call controller 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 controller to said application computer, packetized messages indicative of the information contained in, or associated with, said telephone calls.

An article comprising a computer readable medium having instructions stored thereon which when executed causes:

• transmission of, from an application computer communicably connected to a call controller 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
• transmission of, from said call controller to said application computer, packetized messages indicative of the information contained in, or associated with, said telephone calls.
