Here is the situation:
Customer will have VM only with Exchange 2000 on box. Unity will be standalone DC, in it's own domain.
1. How complicated would it be in the future to make Unity Unified Messaging. Customer is currently using Exchange 2000. How difficult is it to use DiRT. Will it preserve auto attendant settings and recordings?
2. In the present situation can you dial an extension and have the phone ring of someone who does not have a VM box. Would we use internet subscribers in this situation? Is internet subscribers for UM only? Or would we transfer the call to CallManager and have CM transfer to the extension?
3. For those users who will have VM, do they need to purchase additional CAL's?
4.Can you enter a user in Unity who has an extension in Unity without a VM?
5. If we are doing a VM only, standalone in it's own domain without attaching to customer's AD. Can i prestage at my office and plug in to customers site without any problems.
Thanks in advance
