If such REGISTER contains a Record-Route it means that a proxy has added it so the registrar (UAS) MUST mirror "Record-Route" in the 200 response. This is what RFC 3261 states, why do you think it's wrong??
I would think his objection would be based on the fact that RR is not used with REGISTER, but rather Path.
Right, but anyhow if there is a Record-Route in the REGISTER this is because some proxy before the registrar added it :)
