Re: [Sip] Signing P-Asserted-Identity

I thought that the beauty of P-A-I was that my telco can happily claim that
I'm the Queen of the Night without all the bother of checking to see if
I'm a soprano, or can even sing that many notes in a row. So I guess
I don't see what the point is being extra sure that the fiction is a super
reliable fiction.

And since it seems to only be within a given administrative realm, why
isn't TLS or many other possible techniques adequate?

Howdy,
As the discussions about RFC4474 Identity, E.164, and all that seem of the type that will take a very long time to resolve, I've submitted an ID about a private extension for "Asserter Identity", which works in concert with the P-Asserted-Identity mechanism.  It works very similarly to RFC4474, but doesn't sign quite the same things, and can be used to sign TEL URI's, fwiw.

Comments welcomed, of course.

        Title           : Private Extensions to the Session Initiation Protocol (SIP) for Asserter Identification within Trusted Networks
        Author(s)       : H. Kaplan
        Filename        : draft-kaplan-sip-asserter-identity-00.txt
        Pages           : 18
        Date            : 2008-07-07

This document describes private extensions to the Session Initiation Protocol (SIP) that enable a network of trusted SIP servers to identify the asserter of private user identity defined in RFC 3325.  The use of these extensions is only applicable inside a set of administrative domains with previously agreed-upon policies for generation, transport and usage of such information.
This document does NOT offer a general identity model suitable for use between different trust domains, or use in the Internet at large.
