13. A method of establishing a packetized telephony communications session between at least two nodes of a packet data network, over a packet switched data network, comprising:
-
receiving, by a packet network telephony call processing device, over said packet switched data network, a packetized request message requesting a telephony service from a first node to communicate with a second node; and interfacing said packet network telephony call processing device with an application program over said packet switched data network using packetized messages to exchange session information and to provide control to enable said requested telephony service, said application program being located separately from one of said at least two nodes. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26)
