A New Internet-Draft is available from the on-line Internet-Drafts directories. Title : Simple Gateway Control Protocol (SGCP) Author(s) : M. Arango, C. Huitema Filename : draft-huitema-sgcp-v1-02.txt Pages : 82 Date : 25-Sep-98 This document describes an application programming interface (SGCI) and a corresponding protocol (SGCP) for controlling Voice over IP (VoIP) Gateways from external call control elements. The SGCP assumes a call control architecture where the call control 'intelligence' is outside the gateways and handled by external call control elements. The document is structured in 5 main sections: * The introduction presents the basic assumptions and the relation to other protocols such as H.323, RTSP, SAP or SIP. * The interface section presents a conceptual overview of the SGCP, presenting the naming conventions, the usage of the session description protocol SDP, and the five procedurs that compose SGCP: Notifications Request, Notification, Create Connection, Modify Con- nection and Delete Connection. * The protocol description section presents the SGCP encodings, which are based on simple text formats, and the transmission procedure over UDP. * The security section presents the security requirement of SGCP, and its usage of IP security services (IPSEC). * An example section presents two detailed examples of call set up procedures using SGCP. * The description of the changes between version 1.0 and version 1.1 Internet-Drafts are available by anonymous FTP.

Send a message to: mailserv@ietf.org. In the body type: "FILE /internet-drafts/draft-huitema-sgcp-v1-02.txt". NOTE: The mail server at ietf.org can return the document in MIME-encoded form by using the "mpack" utility. To use this feature, insert the command "ENCODING mime" before the "FILE" command. To decode the response(s), you will need "munpack" or a MIME-compliant mail reader. Different MIME-compliant mail readers exhibit different behavior, especially when dealing with "multipart" MIME messages (i.e. documents which have been split up into multiple messages), so check your local documentation on how to manipulate these messages. Below is the data which will enable a MIME compliant mail reader implementation to automatically retrieve the ASCII version of the Internet-Draft.
