Can someone tell me my options for notification of voice messages if we are not unified enabled? Unity 4.2.1
Ahh, now I think I understand. Sorry for the earlier confusion.
Take a look at this link. It's an older doc, but should still be mostly applicable:
Essentially, you can have something like a GDM notify alternate extensions, or you could create rules that would forward message copies to other boxes as well.
Is this more along the lines of what you are hoping to do?
If you want to do a second line on your phone and have messages sent to that extension that is possible. However this will need to be a shared line.
You will only get the mail icon on the display. No red light.
Make a tech support subscriber in Unity and configure the lines on the phones in ccm.
