Added. However, I must say I remain confused about handling of loose routes and H-I. In my example, the request will go from H-B to OB-B due to a route learned via a Path header field in a REGISTER. As such, that request should also contain a Route header pointing to OB-B. What would H-I look like in that case?

Actually, I think what you see in the call flow is not the last leg, but the one
before (i.e. to OB-B).

I would suggest that Jonathan adds the last leg to <b>, including the
Request-URI being replaced by the registered contact.

I also noticed that on the example call flow in section 4, the R-URI on the last leg should be that of the contact address ([EMAIL PROTECTED]).

Hi,

The draft-holmberg-sip-target-uri-delivery-01.txt draft
contained text
on why the P-Called-Party-ID header was used. Would it be a
good idea
to keep that text in this spec, because I have already received questions regarding that.

Regards,

Christer




A New Internet-Draft is available from the on-line

        Title           : Delivery of Request-URI Targets to User Agents
        Author(s)       : J. Rosenberg
        Filename        : draft-rosenberg-sip-target-uri-delivery-00.txt
        Pages           : 12
        Date            : 2008-10-26

When a Session Initiation Protocol (SIP) proxy receives a request targeted at a URI identifying a user or resource it is
responsible
for, the proxy translates the URI to a registered contact
URI of an
agent representing that user or resource. In the process, the original URI is removed from the request. Numerous use
cases have
arisen which require this information to be delivered to the user agent. This document describes these use cases and defines an extension to the History-Info header field which allows it
to be used
to support those cases.
