Hi all,

Thanks Vijay for the GenArt review.
I've just submitted a v-06 to address your comments and here is my feedbacks:

[MM] Indeed, I can see that for people not very aware of IETF and 3GPP vocabulary for call diversion service, it can be confusing. I prefer not to add a call flow in the problem statement section but I did some updates in the wording and inserted the Alice, Bob and Carol users for a better understanding.

[MM] Nits is corrected. About your comment, actually, this I-D is only standardizing "orig-cdiv" parameter. This is the reason why "sescase" and "regstate" appear, as part of a normal session establishment and before any call diversion while the new parameter can appear only when this event occurs (as added by this I-D).. I hope it's clearer for you.

I hope it's ok.

Best regards,
Marianne

Summary: This draft is on the right track but has open issues, described in the review.

Major issues: 0

Minor issues: 1 

Nits/editorial comments: 1

Minor:

- S1.3: I am not sure I follow the logic in the problem statement.  Who
 is the "diverting" user?  The user to who the call was destined?  If so,
 best to say that explicitly.  (To be sure, I looked into rfc5502 as well,
 and it does not define "diverting" user either.)  A bit below (in S4), you  
 use the term "served" user to refer to the diverting user.  All in all, the  
 terminology here could be refined.  I suspect that the "originating" user 
 is the callee.  

 Concretely, I think that the first paragraph of S1.3 should be re-written,
 perhaps with a figure (?) to explain the call flow, or at least some
 context using Alice, Bob and Carol as the example in S7.1 does (I suspect
 that Carol is the "diverting" user here).

Nits, typos:

- S4, step 3: s/user an INVITE that/user as an INVITE that/
 Also, the "secase" and "regstate" parameters are what you are standardizing
 this I-D, as such you mention this before S4 so the reader knows that 
 these are the new parameters.  Same for "orig-cdiv" parameter.
