Thanks Al. I finally broke down and called Avaya. I spent 1/2 hour on the phone with a very nice woman who was as stumped as we have been... she put me on hold for a while..... here's what it was. In the COR, "Restriction Override" has to be set to "none". I don't completely understand it yet, I need to do more research, but that fixed it. The definition in the documentation for Restriction Override is

Restriction Override
Allows the specified users to bypass restriction on conference, transfer or call
forwarding operations.
Valid entries

attendant - A telephone with a COR that is inward restricted cannot receive public network, attendant-originated, or
attendant-extended calls. Enter attendant to give your
attendants the ability to override this restriction.

all - Enter all if you want all of the users with this COR to
override inward restrictions.

none - Enter none if you do not want any users of this COR to
bypass the restrictions.
