We currently have 10 digit Unity Mailboxes. Is there any way to set up a call handler/subscriber box that would prefix 6 digits. Our users want to be able to dial another user from the Auto attendant by entering 4 digits. I understand that Unity is not a Tenant based system, but I was hoping there might be some creative solution somewhere
The easiest way to handle this is to provide alternate extensions (4 digits) to your users - then nothing else needs to be done.
If you have a more complex situation where the 4 digit extensions are not unique then you'll have to get a little fancier. If you are running 4.2(1), there is a prefix capability on call handlers that's exposed in BulkEdit - you can indicate what digits should be tacked on to the begining of a string when a user dials an extension from that particular call handler - then you can setup different handlers with different prefixes for different regions (or however you have your directory configured).
Versions of Unity prior to 4.2(1) don't have this ability - you may need to apply an ES to get this in 4.2 I believe, I'll have to check the notes if you need to go down this route.
