Abstract: A computer telephony interface (CTI) applications computer interfaces to a Internet telephony system which utilizes, preferably, the session initiation protocol (SIP). In one preferred technique, an additional pass through server is added to connect end users to their associated SIP proxy server, and to connect a CTI applications computer to the system.

Abstract: A software ACD is described that is interposed between a switch or packet telephony environment, and an applications computer running a call processing application. The ACD may pass through primitive commands from the applications computer for direct execution by the switch or packet telephony environment, or in response to complex commands from the applications computer it may generate one or more different commands for execution by the switch or telephony environment.

Abstract: A communication management method and apparatus is presented. Such method and apparatus operate to transmit, from an application computer in communication with a gatekeeper which is connected to a data network, messages indicative of (a) telephone calls in progress at an endpoint of the data network, or (b) such endpoint, and to transmit, from the gatekeeper to the application computer, messages indicative of a variety of information contained in the telephone calls so as to process such information for a variety of applications. The invention provides protocols for classifying incoming messages and prioritizing these messages for the presentation to, and utilization by, a system user.

Abstract: A method and apparatus are presented for transmitting, from an application computer in communication with a gatekeeper which is connected to a data network, 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, messages indicative of a variety of information contained in the telephone calls so as to process such information for a variety of applications. The invention contains a method for providing to a user of the system information relative to the incoming caller and to the subject of the call.

Abstract: A method is presented 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 the data network, or indicative of such endpoint, and transmitting, from the call controller to the application computer, packetized messages indicative of a variety of information contained in, or relevant to, the telephone calls so as to process such information for a variety of applications. Apparatus to implement the method is also presented.
