A system for telephone service, the system comprising:
- a Centrex served location;
- and
- a voice over Internet protocol (VoIP) provider served location electrically coupled to the Centrex served location using an IP network, wherein the Centrex served location has an end point from the VoIP provider served location, and users of the system call endpoints at the Centrex served location and endpoints at the VoIP provider served location using abbreviated dialing without incurring local or toll usage charges.
A method for providing telephone service, the method comprising:
- electrically coupling a Centrex served location to a voice over Internet protocol (VoIP) provider served location using an IP network;
- and
- terminating an end point from the VoIP provider served location at the Centrex served location, wherein users of the Centrex served location and the VoIP provider served location call endpoints at the Centrex served location and endpoints at the VoIP provider served location using abbreviated dialing without incurring local or toll usage charges.
A system for telephone service, the system comprising:
- a Centrex served location;
- and
- a voice over Internet protocol (VoIP) provider served location electrically coupled to the Centrex served location using an IP network, wherein the Centrex served location has an end point from the VoIP provider served location comprising an integrated access device (IAD) implemented as a customer provided equipment (CPE) device that is implemented in addition to other CPE devices in the Centrex served location and that operates as a media gateway that converts analog/time division multiplexing (TDM) voice traffic into Internet protocol (IP) packetized VoIP compliant signals, a Class 5 switch having a primary rate ISDN (PRI) facility is terminated on the IAD, and users of the system call endpoints at the Centrex served location and endpoints at the VoIP provider served location using abbreviated dialing without incurring local or toll usage charges.
