A New Internet-Draft is available from the on-line Internet-Drafts directories. Title : SIP-IN Interworking Protocol Architecture and Procedures Author(s) : V. Gurbani, F. Haerens, V. Rastogi Filename : draft-gurbani-sin-00.txt Pages : 26 Date : 16-Apr-02 The aim of the SIP/IN Interworking (SIN) IETF design team is to consider the support of existing IN-based applications in a SIP- based IP environment for IP-Host-to-Phone calls. There are many telephony applications based on IN: 800 (freephone), PSTN VPN, credit card calling, to name a few. The design team work items are: o Interpreting IN Call Models for the SIP environment o Mapping IN messages into (sequences of) SIP messages and vice versa o Mapping IN parameters into SIP parameters and vice versa o Defining SIP extensions, if necessary It was agreed that the contributors on the SIN design team should first publish respective I-Ds, which are then used as the basis of one or more Informational RFCs that will be the major output of the design team. This draft is the first output of the IETF SIN design team and addresses the first work item. It outlines the architecture and procedures of SIP-IN (SIN) Internetworking as well as establishes the call model mapping between the IN Call Model and the SIP protocol state machine. An overall objective is to ensure that IN control of VoIP services in networks can be readily specified and implemented by adapting standards and software used in the present networks. This approach leads to services that function the same when a user connect to present or future networks, simplifies service evolution from present to future, and leads to more rapid implementation.

Send a message to: mailserv@ietf.org. In the body type: "FILE /internet-drafts/draft-gurbani-sin-00.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.
