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.
1. If you plan ahead, transitioning to UM from VM can be easy this is, in fact, one of the reasons I wrote the DiRT tool in the first place. Theres a snappy white paper that talks about how to plan ahead when youre deploying VM with an eye towards going to UM down the road that will be helpful to you here:
2. Yes, you can create as many internet subscribers as you like and they can be used to transfer to extensions or remote phone numbers (i.e. you can include a trunk access code and dial a CO number) no problem. You can also use call handlers for this if you like, however internet subscribers have the advantage of being able to be listed in the name lookup handlers which allow outside callers to find folks by name (handy if you have a legacy voice mail system youre phasing out and you want everyone to be findable in the Unity alpha directory).
3. No, you dont need CALs for VM only users theyre included in the license that comes with Unity. So long as these users ONLY access their messages over the phone or via the separately licensed PCA web inbox, youre cool. If they use another desktop client to access their inbox, then they need to pony up for a CAL.
4. yes see #2.
5. If its all on one box and you arent going to make it a member of an existing domain out there, sure. You cant change the server name or the domain its installed it post install, however, so that only works for the completely self contained installation (which is what it sounds like you want to do).
I'm not able to access my old voice mail messages all of a sudden. The recording says something like 'the message is currently not available'. This has never happened before in all the years I have been using this system. I have t...
