--NextPart A New Internet-Draft is available from the on-line Internet-Drafts directories. Title : Applying Loose Routing to Session Initiation Protocol (SIP) User Agents (UA) Author(s) : J. Rosenberg Filename : draft-rosenberg-sip-ua-loose-route-01.txt Pages : 19 Date : 2007-06-12 A key part of the behavior of the Session Initiation Protocol (SIP) is that SIP proxies rewrite the Request-URI as a request moves throughout the network. Over the years, experience has shown this to be problematic. It makes it difficult to use Request URI for service invocation, complicates emergency services, makes it more complex to support aliases, and so on. Architecturally, it confounds the concepts of address and route. This document proposes to change this through a new mechanism called UA loose routing.

A list of Internet-Drafts directories can be found in http://www.ietf.org/shadow.html or ftp://ftp.ietf.org/ietf/1shadow-sites.txt Internet-Drafts can also be obtained by e-mail. Send a message to: mailserv@ietf.org. In the body type: "FILE /internet-drafts/draft-rosenberg-sip-ua-loose-route-01.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. --NextPart Content-Type: Multipart/Alternative; Boundary="OtherAccess" --OtherAccess Content-Type: Message/External-body; access-type="mail-server"; server="mailserv@ietf.org" Content-Type: text/plain Content-ID: <2007-06-12225133.I-D@ietf.org> ENCODING mime FILE /internet-drafts/draft-rosenberg-sip-ua-loose-route-01.txt --OtherAccess Content-Type: Message/External-body; name="draft-rosenberg-sip-ua-loose-route-01.txt"; site="ftp.ietf.org"; access-type="anon-ftp"; directory="internet-drafts" Content-Type: text/plain Content-ID: <2007-06-12225133.I-D\@ietf.org> --OtherAccess-- --NextPart-- _______________________________________________ I-D-Announce@ietf.org https://www1.ietf.org/mailman/listinfo/i-d-announce
