Claim:
A cable modem integrated session boarder control circuit coupled to: a voice over internet protocol (VoIP) device via a local area network; and a cable modem circuit (CM) for communication with a cable modem termination system (CMTS) via a Data-Over-Cable Service Interface Specification (DOCSIS) network; the session boarder control circuit comprising, as instructions stored in a memory and executed by a processor, a back to back user agent system (B2BUA) embedded with a DOCSIS dynamic quality of service system (DQoS); the B2BUA, in response to receiving a frame via the local area network, determining if the frame is a Session Initiation Protocol (SIP) invite message; in response to the B2BUA determining that the frame is a SIP invite message, the DQoS: i) generates a dynamic services addition Request message (DSA-REQ) to the CMTS; and ii) generates a corresponding SIP invite message to a SIP proxy.
