Hi Christer; Thanks for the comments and for reviewing the draft. My comments inline..

However, it is unclear when and how the parameters would be used in a Contact header field. I think this is already described in the section 10.4. "In the latter case, the specific header parameter field in the Contact header becomes the header field parameter that is used in the hi- target-param in the hi-entry when the request is retargeted." > > > 2. Tel to Sip transformation: ENUM (technical) > > Section 5 talks about transformation from Tel to Sip, according section 19.6.1 of RFC 3261. However, the transformation can also be the result of an ENUM DNS lookup. So, maybe some text should be added, indicating that the transformation can be done based on local configuration (the hostpart of the new SIP-URI needs to be taken from somewhere), or based on an ENUM DNS lookup. Are you talking about adding target-param based on ENUM lookup or simply recording the transformation/resolution in H-I? Anyway, do you want to suggest some text as a co-author of the draft? :-) > > > 3.

The draft doesn't limit the behavior of the entity recording H-I to only record SIP-URI, it just says to record the R-URI. > > 4. Home proxy (editorial) > > The draft mentions "home proxy", but there is no reference or definition for it. I guess it should be "registrar", or something. I guess we can call it a "registrar" or at the first instance include a text used in RFC 3327. REGISTRAR or a "home proxy" (a proxy serving as the terminal point for routing an address-of-record) > > > 5. Out-of-dialog request (editorial) > > Section 5 talks about "request not associated with an early or established dialog", while section 6.1 talks about "new or out-of-dialog request". In both cases the text refers to the request that can carry History-Info, so the wording should be consistance. For example "out-of-dialog requests or initial requests for a dialog". I agree. > > > 6. Appearence (editorial) > > Section 5 says in which message types History-Info "can appear". It would be better to say for which message types the document/specification defines the usage of History-Info. > Sounds good. > > 7. Misc (editorial) > > There are, throughout the document, some inconsistance between usage of "header" vs "header field", "this document" vs "this specification", the usage of capital letters for requests and SIP entity names etc, but I guess that can be taken care of by the authors without a list of every occurance here. We thought we were pretty careful with this as John has pointed these out before. We will go through the draft and make sure there is consistency with the wording.
