I have a BCM50 and the customer wants to dial out using outlook. The BCM is connected to the customers network for lan access only right now. I noticed a post from "Keypd" from 5-4-10 that is referring to Unified Messaging. If my customer wants to add the ability to view a contact in outlook and click on "dial" from his computer is the only thing that is needed to be added is a "Unified Messaging" keycode and the programming?
