Abstract:
1. A method for providing full-featured Voice-over Internet Protocol (VoIP) telephony service, comprising the steps of: receiving in a first network a packet-based VoIP call, wherein the first network is a Hybrid-Fiber Coax network; translating, within the first network, the VoIP call into a Time-Division Multiplexed (TDM) call compatible with a second network having a capability of processing TDM calls and providing at least one feature for the TDM call, the translating comprises sub-steps of (1) performing required signal processing protocols in the first network to allow the VoIP call to interact with the first network as if the first network was performing switch-based processing functions and (2) mapping IP signaling information developed in the first network into a format suitable for processing by the second network; routing the TDM call to the second network; processing the TDM call in the second network; and routing the TDM call to its intended destination.
