Hi all, 

I have a question about draft-ietf-sip-replaces-03.txt:
Section 2 says:
   ... the Replaces header is
   frequently used in combination with the REFER [4] method ...

but section 3 contains:
   ... if
   a Replaces header field is present in a request other than INVITE,
   the UAS MUST reject the request ..

I think it makes a lot of sense to allow replaces with REFER; e.g. in the
call park scenario you could have a web page with all call and make a "click
to retrieve from park" to have it on your desk phone.
And that is similar to what's described in
draft-ietf-sipping-cc-transfer-01.txt, although I have a notion that there
is some difference but I don't manage to get it out of the draft. 

Thanks
