NETWORK TELEPHONY APPLIANCE AND SYSTEM FOR INTER/INTRANET TELEPHONY
First Claim
1. A network appliance for providing packetized data over a packet data network, comprising:
- a network controller subsystem coupled to said packet data network;
a digital signal processing subsystem coupled to said network controller subsystem, the digital signal processing subsystem further comprising a computer program for detecting incoming calls and initiating call sessions;
a signal conversion subsystem coupled to said digital signal processing subsystem; and
a user interface subsystem coupled to both the signal conversion subsystem and said digital signal processing subsystem.

Abstract
A network appliance (100) is provided having a network controller subsystem (110) for coupling the appliance (100) to a data network for providing and receiving data packets to and from a packet data network. A digital signal processing subsystem (120) is coupled to the network controller subsystem (110). A signal conversion subsystem (130) is coupled to the digital signal processing subsystem (120) and a user interface subsystem (160) is coupled to both the signal conversion subsystem (130) and the digital signal processing subsystem (120). The digital signal processing subsystem (120) operates under the control of a computer program which is capable of detecting incoming calls, initiating call sessions, and preferably, implementing advanced telephony features.
