Abstract

Voice over Internet Protocol (VoIP) service is established in a network that that includes a Regional/Access Network (RAN) that facilitates differentiated end-to-end data transport between an Application Service Provider (ASP) and a Customer Premises Network (CPN) that includes Customer Premises Equipment (CPE). Application Programming interface (API) calls are used at the ASP to communicate with the RAN to establish VoIP service for the user having a user selected bandwidth and/or QoS associated therewith.

wherein the means for using the application programming interface calls to communicate with the regional access network to establish voice over Internet Protocol service for the user comprises;

means for using application programming interface calls to communicate directly with the regional access network without traversing any of the intermediate network nodes to obtain a bandwidth range, quality of service capabilities, and at least one derived service option from the regional access network; and

means for presenting to the user via the application service provider a bandwidth within the bandwidth range and a quality of service option within the quality of service capabilities and the at least one derived service option.

13. The system of claim 12, wherein the customer premises equipment comprises a routing gateway.

14. The system of claim 12, further comprising:
