Using Unity VMO 4.0.5 with Exchange 2K. Tested "integration" with Aspect ACD to provide ACD phones with Unity VMO. MWI is done via Unity Message Notification Work Phone using *2NNNN, where NNNN is the 4 digit mailbox id and ACD extension. CCM has route pattern that sends all *2NNNN calls to ACD which either turns the MWI light on or off. Question - is there a Unity system variable for the mailbox id, that could be used in a subscriber template to ease the subscriber create process? Subscriber Template Message Notification Work Phone would have the value *2?variable? so that admin does not have to update this field for each new subscriber.
