script and OCSUMUTIL to confi gure and link the two systems. The OCSUMUTIL creates
contacts for Exchange auto-attendants and the phone number for subscriber access to Exchange
unifi ed messaging. The OCSUMUTIL also ensures that Enterprise Voice location profi les in
OCS match up to an Exchange UM dial plan.
