Access independent common architecture for real-time communications services for networking environments
First Claim
1. A method of placing a call, comprising:
- receiving a call request to a destination phone number from a caller phone at a first border element, wherein the caller phone is connected to the first border element using a time division multiplexing technology;
forwarding the call request from the first border element to a call control element, wherein the first border element communicates with the call control element using a session initiation protocol, wherein the call control element only communicates in the session initiation protocol, wherein the call request is for being sent via the call control element to a second border element connected to a destination phone, wherein the second border element is selected from a plurality of second border elements, wherein the plurality of second border elements comprises a session initiation protocol to H.323 border element, a session initiation protocol to a media gateway control protocol border element, a session initiation protocol to a media gateway control border element, a session initiation protocol to a signaling system 7 protocol border element, a session initiation protocol to a central authentication service protocol border element and a session initiation protocol to an integrated services digital network protocol border element;
establishing the call between the caller phone and the destination phone;
receiving, by the first border element, a hangup message sent from the destination phone, wherein the receiving the hangup message sent from the destination phone comprises receiving a bye command sent from the second border element via the call control element; and
disconnecting the caller phone from the first border element.

Abstract
An access architecture for real-time communications is described. The architecture includes an inter-architecture network utilizing a single protocol, a plurality of border elements in communication with the inter-architecture network and with an external network, and one or more call control elements in communication with said inter-architecture network. The external network utilizes any of a variety of known networking technologies and protocols. The inter-architecture network utilizes a single protocol such as SIP. The present architecture provides a single common infrastructure for offering real-time communications services independent of call control protocols and networking technologies.
