John 

I agree with your "an entity registers a contact for an AOR".
I still do not like the "on behalf of", so your proposal with "for" is ok for me.

[JRE] The point is, I don't think an entity registers an AOR, I think an entity registers a contact for an AOR. So I still prefer the text in my working copy:
"The mechanism MUST NOT prevent UAs attached to a SIP-PBX registering with the SIP-PBX for AORs based on assigned telephone numbers, in order to...".
(In fact I really preferred my original "on behalf of" if changing this to "for" did not help).
