That's how we learn. Anyway, it may make a slight reduction but it would probably come closer to reducing the time on internal calls. We use it in a clinic setting. We have it installed on the workstations in each doctor pod and assistant pod as well as from the front desk. The front desk shoots a message to the appropriate hall so the assistant will know when they have a patient ready to come back. It is being used a little more now for just quick messages as well. I think as we go forward and more of the users get used to it it should help in the Exchange load as well.
I really like it because it is strickly internal communication and is extremely simple to use.
