1. A client proxy signaling system for an IP telephony network comprising:
- at least one terminal coupled to an IP network; and
a terminal proxy coupled to said IP network communicable with said at least one terminal for providing logical call processing signaling on behalf of said at least one terminal, wherein said terminal proxy communicates with and manages the call processing logic for said at least one terminal with respect to the remainder of a telephony network.

Abstract
A system and method for supporting communications services on behalf of a communications device which cannot provide those services itself in a communications network based on functional signaling. A terminal is designed to identify a supporting server/terminal proxy upon initialization. Henceforth, the terminal provides each user input stimulus to the server and responds to stimulus from the server. The server manages the state machine of the terminal, provides supplementary services, and meets protocol requirements for the network interface.

14. A method of providing client proxy signaling in an IP telephony network for a terminal that cannot perform such signaling itself, said method comprising the steps of:
-
(a) identifying a terminal proxy on an IP network upon initialization of the terminal; and
(b) exchanging call processing messages between the terminal and the terminal proxy such that the terminal proxy manages the call processing logic for the terminal on behalf of the terminal with respect to the remainder of a telephony network.

15. A client proxy signaling system for an IP telephony network comprising:
-
means for identifying a terminal proxy on an IP network upon initialization of a terminal; and
means for exchanging call processing messages between the terminal and the terminal proxy such that the terminal proxy manages the call processing logic for the terminal on behalf of the terminal with respect to the remainder of a telephony network.

16. A client proxy signaling computer program product for an IP telephony network having a medium with a computer program embodied thereon comprising:
-
computer program code for identifying a terminal proxy on an IP network upon initialization of a terminal; and
computer program code for exchanging call processing messages between the terminal and the terminal proxy such that the terminal proxy manages the call processing logic for the terminal on behalf of the terminal with respect to the remainder of a telephony network.
