Call control element constructing a session initiation protocol (SIP) message including provisions for incorporating address related information of public switched telephone network (PSTN) based devices
First Claim
1. A method of forming a multi-media communication path between a calling communication device that operates using a first protocol and a destination communication device that operates using a second protocol, comprising:
- receiving, by a call control element of a multi-media provider system, a request for a multi-media service;
processing, by the call control element, the request for generating a signaling protocol message, wherein the processing by the call control element is in response to receiving a redirect message from a network routing engine indicating that the signaling protocol message is to be directed towards a gateway border element in communication with a circuit based network of the destination communication device; and
sending, by the call control element, the signaling protocol message to the destination communication device to form the multi-media communication path between the calling communication device and the destination communication device, wherein the destination communication device comprises a circuit based communication device and wherein the signaling protocol message includes a header portion, a first body portion and a second body portion separate from and different than the header portion and the first body portion, wherein the second body portion includes predetermined address specific information and calling party'"'"'s privacy screening indicator information associated with the destination communication device for integrated services digital network user part signaling.

Abstract
A Session Initiation Protocol (SIP) message adapted for use by a multi-media services provider system to form a multi-media communication path between at least a calling communication device adapted to operate using a first protocol (e.g. SIP) and at least a destination communication device adapted to operate using a second protocol, such as Integrated Services Digital Network User Part (ISUP). The SIP message includes a header region having a number of header fields, a first body region having Session Description Protocol (SDP) information related to the calling communication device and a second body region having ISUP related addressing information associated with the destination communication device.

7. A system of forming a multi-media communication path between a calling communication device that operates using a first protocol and a destination communication device that operates using a second protocol, comprising:
-
a call control element; for receiving a request for a multi-media service; for processing the request for generating a signaling protocol message, wherein the processing is in response to receiving a redirect message from a network routing engine indicating that the signaling protocol message is to be directed towards a gateway border element in communication with a circuit based network of the destination communication device; and for sending the signaling protocol message to the destination communication device to form the multi-media communication path between the calling communication device and the destination communication device, wherein the destination communication device comprises a circuit based communication device and wherein the signaling protocol message includes a header portion, a first body portion and a second body portion separate from and different than the header portion and the first body portion, wherein the second body portion includes predetermined address specific information and calling party'"'"'s privacy screening indicator information associated with the destination communication device for integrated services digital network user part signaling. - View Dependent Claims (8, 9, 10, 11, 12)
