Folks, I wanted to call your attention to this updated 3pcc document. It deals with implementation issues that have come up since the publication of the original draft. Note that, specifically, it no longer recommends carrying SDP in the ACK, but rather using a re-INVITE. It talks about QoS integration, as discussed by Gonzalo at past meetings. It also includes some notes at the end on SIP features that you really, really, *really* want to support so that your phone, PC, or whatever, can receive features and services provided by a controller. As such, I would strongly recommend that people who build UAs take a look at this draft, and plan on supporting the features discussed there. If anyone has questions on the value of doing this, feel free to contact me. --- Jonathan D.

Title : Third Party Call Control in SIP Author(s) : J. Rosenberg, J. Peterson, H. Schulzrinne, G. Camarillo Filename : draft-rosenberg-sip-3pcc-01.txt Pages : 15 Date : 22-Nov-00 This document discusses the usage of the Session Initiation Protocol (SIP) for third party call control. Third party call control refers to the ability of one entity to create a call in which communications is actually between other parties. We present a SIP mechanism for accomplishing third party call control that does not require any extensions or changes to SIP. A URL for this Internet-Draft is: http://www.ietf.org/internet-drafts/draft-rosenberg-sip-3pcc-01.txt Internet-Drafts are also available by anonymous FTP. Login with the username "anonymous" and a password of your e-mail address. After logging in, type "cd internet-drafts" and then "get draft-rosenberg-sip-3pcc-01.txt". 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-3pcc-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.
