Re: comments on draft-kaplan-sip-secure-call-id-00.txt

Hey Jonathan,
Thanks for reviewing the draft!  This draft is just about making UA's send actual Call-ID values which do not reveal sensitive information, so that middleboxes are not made to change them purely for security purposes.

The other draft, session-id, was changed - rev 02 is the latest - and that rev is only about troubleshooting not dialog matching. This secure-call-id draft is the one and only thing I propose for dialog matching purposes (and it is the actual Call-ID header field value).
