Re: WGLC for draft-ietf-sip-ua-privacy

Hi John,

Thank you for the comments.

See inline.

I agree and will replace the text with the one you proposed.

The out-of-dialog request indeed meant the MESSAGE request.
I checked the RFC and found that MESSAGE requests don't
include the Contact header as you pointed out.
I will delete the sentence.

Thank you!
