发明名称 System and method of providing a high-quality voice network architecture over IP centrex
摘要 A system and method are disclosed for providing high quality sound communications in an IP Centrex environment. The method aspect of the invention comprises, from a network switch, negotiating between a first customer premises equipment (CPE) and a second CPE, the negotiation being related to a possible quality of a call between the first CPE and the second CPE. Next, the switch controls mapping between a dialing plan and a network address, determining a network address of the first CPE and the second CPE and connecting the call between the first CPE and the second CPE. In this manner, the highest quality and broadest bandwidth possible between the first CPE and second CPE through the IP Centrex environment may be used for the call.
