To one further question - if we are using extension mobility and log into a phone then logout out of the hunt group does that setting stay with the user if they log into another phone? or will they be automatically logged back into the huntgroup when the logout of EM.
Well, you wll first need to see if you can assign EM DN to a hunt group, if you can then you should be technically able to logout while using EM.
