Hello,

> Your posited UA is going to reject out-of-dialog refers (at least in the context of a given dialog).
> Is it going to reject all refers? 

If you meant REFERs related to dialogs created by the particular INVITE request, then:
- the UA rejects any out-of-dialog REFERs related to dialogs created by the particular INVITE request as stated in the question below; and
- the UA handles any in-dialog REFER received in a dialog created by the particular INVITE request according to RFC6665. The UA rejects any in-dialog REFER request that would result in an implicit subscription.

If you also meant REFERs related to dialogs created by other INVITE request, then UA can accept or reject them within rules given by RFC6665.

> If your UA did not provide a GRUU, it is (in the context of this dialog) not satisfying the requirements of 6665. 
> ...
> The text you're proposing (if I've got it right) is trying to say "this UA is not using 6665 in the context of this dialog".

Can you please quote the RFC6665 requirement which the UA does not satisfy?

Kind regards

Ivo Sedlacek
