I found it so I am making notes here:
In the MiCollab server-manager [ which used to be called the Mitel Applications Suite (MAS) ] under "Applications" select "MiCollab Client Service" next click the "Configure MiCollab Client Service" button on the "MiCollab Client Service Administration" page next select the "Accounts" tab then click the account you want to edit next expand "Account Settings" and then check the box in front of "Enable ACD features in client"
Still not working correctly yet, but the little ACD head with headphones is now in the MiCollab client
